If you know about the current state of affairs, please help keep everyone informed by updating this information. (Discussion)
The WMS Plugin provided functions which are now part of JOSM core. The plugin allowed you to fetch images from any WMS source, and display them as a background image (a layer) within JOSM. It also supported Yahoo! Aerial Imagery and Rectifier like Metacarta and Geothing to display rectified/warped images.
Now that imagery is a core feature, you can open WMS sources from the 'imagery' menu. There is no longer any need to install these features as a plugin. See also the help page in the JOSM Wiki.
Starting with JOSM version 3715, WMS functionality is part of JOSM itself. Users of older version of JOSM may still be using this plugin.

Installing Yahoo! aerial imagery downloader
Yahoo imagery is no longer available
as of 13 September 2011: [1]
To use Yahoo! aerial imagery you will need to install a tool for interfacing with Yahoo to download tiles.
On Windows use the WebKit based downloader called webkit-image as follows
- Download webkit-image.zip
- Unzip it.
- Move the contents so that the DLL files and the EXE file are somewhere "on your system path". The best way to achieve this might be to place them alongside josm-latest.jar Keep the 'imageformats' subfolder alongside too (so all the contents of the zip).
- Restart JOSM
- Do 'WMS' menu -> YAHOO (Webkit)
You should start to get Yahoo! imagery (may take up to 30 seconds to start showing). If not, it may not be finding the DLL files correctly.
Note: If you don't want to place webkit-image in your system path or the JOSM directory you don't have to. By editing the download program you can specify an absolute or relative path to the webkit-image executable. Examples:
- webkit/webkit-image {0} - loads webkit-image.exe from the subdirectory webkit relative to the JOSM installation directory
- D:/webkit/webkit-image {0} - uses webkit-image D:\webkit\webkit-image.exe
Linux kernel Operating Systems
On Linux you can use different downloaders: gnome-web-photo or webkit-image.
OpenSuSE, SuSE and SLES Distributions
release 11.3 (opensuse)
- gnome-web-photo : this can be installed using yast
- webkit-image : can be built for Qt if you have development tools installed. You will need to use yast to install:
- libQTWebKit4-devel and friends
- libqt4-devel and friends
- pkg-config
- other more general requirements depending on your build environment
then follow the instructions below for Build from Source
- webkit-image-gtk : try instructions below for webkit-image (GTK+) after installing libwebkit (+friends) and gtk2-devel; you will need to edit an include line in webkit-image-gtk.c so that it points to
gio-unix-2.0/gioand not just
gio, it should read:
#include <gio-unix-2.0/gio/gunixoutputstream.h>
Although the tool should now compile it may not scale tiles correctly within JOSM; use one of the other tools instead
gnome-web-photo for Fedora and Ubuntu
gnome-web-photo is compiled and prepackaged for some distributions, including Fedora and Ubuntu.
Attention: You have to select gnome-web-photo --mode=photo --format=png {0} /dev/stdout at the preferences dialog of the wms plugin.
On Ubuntu 8.10 'Intrepid Ibex'
- Install gnome-web-photo through synaptic (version used 0.3-0ubuntu2)
- Select
gnome-web-photo --mode=photo --format=png {0} /dev/stdoutas the downloader at the bottom of the WMS preferences pane. Then you can choose the "Yahoo Sat" option from the WMS pull down menu to get the background to download. You might have to zoom out a bit if data is not available at the current zoom level.
On Ubuntu 9.04 'Jaunty Jackalope'
The gnome-web-photo package in Ubuntu 9.04 has introduced bugs with JOSM, resulting in mis-aligned and distorted WMS imagery. This can be rectified by installing an older version of gnome-web-photo.
While the common suggestion has been to compile and manually install gnome-web-photo, you can get away with installing the version from Ubuntu 8.10 instead.
- Uninstall any existing version of gnome-web-photo using Synaptic, or by issuing the following command on the command line:
sudo apt-get remove gnome-web-photo
- Download an older version of gnome-web-photo from the Ubuntu Mirror.
- gnome-web-photo_0.3-0ubuntu2_amd64.deb for 64 bit Ubuntu systems.
- gnome-web-photo_0.3-0ubuntu2_i386.deb for 32 bit Ubuntu systems.
- Once the file has downloaded, double click it to install it to your system. If for some reason this doesn't work, you can install it from the command line using
sudo dpkg -i gnome-web-photo_0.3-0ubuntu2_*.deb
- Note, this may introduce problems when you upgrade to later versions of Ubuntu, so you may need to uninstall this package before you do so. You can do this by following the instructions in step one.
- Every time you update your packages Ubuntu will attempt to update this package to the broken version. To stop this from happening add the following three lines to your /etc/apt/preferences (you may have to create this file)
Package: gnome-web-photo
Pin: version 0.3*
Pin-Priority: 1001
- This may introduce dependencies problems, the package requires libxul0d. Run the command
sudo apt-get -f installand it should fix any problems.
- Select 'gnome-web-photo --mode=photo --format=png {0} /dev/stdout' as the downloader at the bottom of the WMS preferences pane. Then you can choose the "Yahoo Sat" option from the WMS pull down menu to get the background to download. You might have to zoom out a bit if data is not available at the current zoom level.
On Ubuntu 9.10 'Karmic Koala'
The gnome-web-photo package in Ubuntu 9.10 does not seem to download any data.
Repeat the steps listed above for 9.04 by installing the old version of the package and it works.
On Ubuntu 10.04 'Lucid Lynx'
- The gnome-web-photo((version used 0.8-0ubuntu2)) package in Ubuntu 10.04 does not seem to download any data.
- Goto Preferences>WMS>Add and give this address http://wms.latlon.org/?layers=yhsat&
On Ubuntu 10.04.1 'Lucid Lynx'
- Install the latest gnome-web-photo((version used 0.8-0ubuntu3)) package from Synaptic (or any other way you like).
And select 'gnome-web-photo --mode=photo --format=png {0} /dev/stdout' as the downloader at the bottom of the WMS preferences pane in JOSM.
- Has this worked for you or are you only copy-pasting this info? logictheo 16:23, 26 September 2010 (BST)
- I have tested the above and it worked for me. Cipt2001 11:31, 14 October 2010 (BST)
On Ubuntu 10.10 'maverick'
- I have tested the above and it worked for me User:Topodom
Troubleshooting: if you see white stripes
- download gnome-web-photo-fixed from OSM SVN repository
sudo cp gnome-web-photo-fixed /usr/local/bin sudo chmod a+x /usr/local/bin/gnome-web-photo-fixed
- install package netpbm
- in JOSM -> Settings -> WMS, change "gnome-web-photo" to "gnome-web-photo-fixed" in the selection for download program.
webkit-image (QT)
WebKit has some flavors, the main ones are QT-WebKit and WebKit-GTK+. See below for the GTK+ version.
On Debian unstable/sid and testing/wheezy
If you installed josm with aptitude/apt-get you should get webkit-image-gtk installed automatically. If for some reason you don't have it, or it is not working correctly, you can install webkit-image-qt with the following command:
sudo aptitude install webkit-image-qt
If you have both webkit-image-qt and webkit-image-gtk installed and want to make sure that josm is using webkit-image-qt you can either:
sudo aptitude remove webkit-image-gtk
sudo update-alternatives --config webkit-image
go to the josm preferences, WMS tab and change "webkit-image {0}" to "webkit-image-qt {0}".
Building from Source
- Install the following packages: build-essential libqt4-dev (>= 4.4.3[1][2]) libqt4-webkit pkg-config
- Download and compile (you may have to replace moc with moc-qt4, or /usr/include/qt4 with /usr/lib/qt4/include):
wget https://svn.openstreetmap.org/applications/editors/josm/webgrabber/webkit-image.cpp moc webkit-image.cpp > webkit-image.h g++ -I /usr/include/qt4/ -I /usr/include/qt4/QtGui -I /usr/include/qt4/QtNetwork/ webkit-image.cpp -o webkit-image -lQtCore -lQtWebKit -lQtGui -s -O2
- instead of the previous step, you can use the packaged Makefile:
svn co https://svn.openstreetmap.org/applications/editors/josm/webgrabber cd wmsplugin make webkit-image
- Copy it to somewhere in your path:
sudo cp -v webkit-image /usr/local/bin/
- [1] 4.2.1 from current Debian stable/etch is missing files, you'll absolutely need to compile. These files appear not before 4.4.3-1, that is in testing/lenny (checked in Ubuntu archives). You'll have to leave the "clean" state of our stable system to get the Debian testing or unstable package and it's dependencies. To do so, you'd like to add at least one line like
http://ftp.debian.org/debian/ testing main contrib non-free
- into your /etc/apt/sources.list file, or you'll not be able to even see the needed packages. Think twice before allowing any upgrade of existing packages to a more recent testing or unstable version, however, you'll have no choice to get Yahoo imagery working again with current JOSM revisions ...
- [2] Running aptitude I found following packages as mimimum additional install: libqt4-xml, libqt4-dbus, libqt4-script, libqt4-designer, libqt4-sql, libqt4-qt3support, libqt4-svg, libqt4-xmlpatterns, libqt4-help, libqt4-assistant, libqt4-test, qt4-qmake, libqt4-dev (all 4.4.3-1), but your experience may vary.
Experimental Debian and Ubuntu Packages
There are experimental debian and ubuntu packages fro webkit :
you add to your /etc/apt/source.list
deb http://osm.komzpa.net/~mdupont/osm/ gjergi-osm main deb-src http://osm.komzpa.net/~mdupont/osm/ gjergi-osm main
and then :
apt-get install webkitimageqt
see also : https://bugs.launchpad.net/ubuntu/+source/josm/+bug/509061 see also : http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=569040
- one person succeeded installing it and making it work with Ubuntu 10.10 (as gnome-web-photo did not work)
- one person succeeded installing it and making it work with Ubuntu 10.04
- one person succeeded installing it and making it work with Trisquel 4.0
On Mandriva 2010.0
- Prerequisites
urpmi webkitkde-devel libqt4-devel urpmi subversion gcc-c++
- Get the sources and compile
svn co https://svn.openstreetmap.org/applications/editors/josm/webgrabber cd wmsplugin make webkit-image
- As root, copy it to somewhere in your path:
cp webkit-image /usr/local/bin/
Gentoo webkit-image ebuild
The following code is an ebuild that installs webkit-image (QT) on a Gentoo Linux computer. See this Linux Reviews article on how to install custom ebuilds. Using the path
sci-geosciences/webkit-image/webkit-image-9999.ebuild to save the ebuild to within your local Portage overlay should work fine.

webkit-image (GTK+)
It requires GTK+ 2.20+ and WebKitGtk+. Compile and install webkit-image-gtk.c.
Libraries required: libgtk2.0-dev libwebkit-dev.
To compile it, run: gcc -W -o webkit-image webkit-image-gtk.c `pkg-config --libs --cflags gtk+-2.0 webkit-1.0`
(note:it builds but fails with "image == null" errors on Mandriva Linux, whereas Qt version works, on Gentoo too)
success on the following Operating Systems
comments: Ubuntu 10.04: Compiling https://svn.openstreetmap.org/applications/editors/josm/webgrabber/webkit-image-gtk.c a success! Putting the resulting webkit-image(made executable) in the directory /usr/local/bin/ . Doesn't load any yahoo tiles and just says "Exception occured". Once it showed some tiles but they covered tiny rectangles while everything else was "Exception occured".
Mac OS X
- Install XCode (free download from Apple after regstration, see http://developer.apple.com/mac/)
- Install Qt SDK (free download from Nokia, see http://qt.nokia.com/downloads/ "LGPL Downloads", "Download Qt SDK for Mac", in particular the Qt libraries further down the download page)
Download Intel-only binary from http://www.lassitu.de/osm/webkit-image-r13262-qt-4.5-osx10.5.6.zip (MD5 checksum ecf2e2f044ce259af702247729468be1)

Or compile from source:
1. Use svn to check out the wmsplugin from https://svn.openstreetmap.org/applications/editors/josm/webgrabber
$ svn co https://svn.openstreetmap.org/applications/editors/josm/webgrabber
2. In the Makefile, change the LDFLAGS line to read:
LDFLAGS=-framework QtCore -framework QtGui -framework QtWebKit -framework QtNetwork
3. Build the program with make:
$ make
if it fails with webkit-image.h:15:2: error: #error "(The moc has changed too much.)" update the header files with
$ moc webkit-image.cpp > webkit-image.h
4. Copy the
webkit-image program to a directory that is part of the PATH. If you're not sure which directory to use, try this:
$ sudo mkdir -p /usr/local/bin $ sudo cp webkit-image /usr/local/bin
- Unix programs (and Mac OS X) look for programs to execute in a list of directories. This search list is kept in the PATH environment variable. By default, PATH is set to
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/X11/bin. To check the current value of the PATH environment variable, use
echo $PATH. You can copy the
webkit-imageprogram to any of the directories listed in PATH, and JOSM and the wmsplugin will automatically find them.
Since July 2009, no further configuration is necessary. If you've installed
webkit-image in a directory not in the PATH, you need to modify the path given in the Downloader text box at the botton of the wemplugin preferences page.
If you have JOSM installed from ports collection, then you already got webkit-image (QT) compiled and installed, and Yahoo imagery will work out of the box.
You can get source of the WMS plugin from Subversion:
svn co https://svn.openstreetmap.org/applications/editors/josm/webgrabber
Using the WMS plugin
- Load / Download openstreetmap data and go to your favourite area
- Show the 'Layers' panel if it isn't showing already (Click the toggle button: )
- Click the menu option "WMS → Landsat" (or whatever named WMS server you want to use) This should cause it to create a new imagery layer.
- Wait a few moments for it to begin fetching image tiles.
As you pan around it will download more tiles. It also seems to remove tiles which are out of viewing area, to free up memory.
To remove the imagery and stop all WMS downloading, select the layer and click the trash can button. You can also temporarily toggle visibility of the layer (keeps imagery in memory). Right click on the layer (in the layers panel) to access further WMS layer options.
When your WMS layer is selected, the data layer is shown as deselected (dark grey). Simply select your data layer again (often called 'unnamed') to restore normal colours. It is also possible to display the WMS layer "above" the data layer, which will hide the data layer completely. Use the up/down arrows to fix the ordering.
You can adjust the positioning of the imagery by clicking button on the left. In this mode you can drag and drop the WMS layer. Press the button again to lock it in place. This can be useful if the imagery appears to be offset from reality, but note that your GPS unit isn't perfect. A bad GPS signal can cause an entire trace to have an offset from reality, so you may find it useful to check also by downloading other GPS traces recorded for the area.
You may need to adjust your map colours ('Edit' menu -> 'Preferences') to be darker or lighter, to contrast with the images you are using.
Basic troubleshooting
Things to try in case of problem.
no image appears, even after waiting a bit
- adjust zoom level so that the scale in the top left says ~150m, delete the layer (trash can icon), add it again from the menu.
- The plugin may not find the DLL files. Check you have placed all of the webkit-image zip file contents them somewhere on the system path.
images at bad resolution from Yahoo
- adjust zoom level as decribed above. Note that in most regions Yahoo imagery has a lesser resolution than Google Maps.
Exception occurred red tiles
- This can mean the WMS server is temporarily not available. Landsat and OpenAerialMap seem to be prone to periods of non-availability. Delete the WMS layer and try again 10 minutes later.
error : bad parameters red tiles
- Check that configuration -> projection is set to EPSG:4326 or Mercator.
gray tiles
- if you have non-ACSII symbols in the path to your plugin folder in Windows (e.g. cyrillic letters in your name in C:\Documents and Settings\your name\Application Data\JOSM\plugins), a possible solution is to change your name to an equivalent short filename. To find this open a command window and do
dir /x "C:\Documents and Settings"
In its output the column to the left of your name should contain short version of your name, let it be for example 9335~1. Add a line to the batch file starting JOSM:
rem Contents of start_JOSM.cmd set APPDATA=C:\Documents and Settings\9335~1\Application Data start javaw -jar josm.jar
"Plugin requires JOSM update: wmsplugin" at JOSM startup
- Update JOSM: see JOSM to last tested version.
- If the message still appears, the problem is on your side - you have a newer version plugin version than your josm can hande. Go to the plugin preferences page and update there. This should install the last version which is usable in your josm (when necessary does a downgrade of the plugin).
For other troubleshooting you can ask a bunch of JOSM users via various Contact channels. Bugs are tracked on josm trac 'Plugin WMS' component
To reuse the tiles over JOSM sessions without having the reload them from the server, right click on the WMS layer and set a bookmark. During the next session, select the new WMS created by the bookmark in the WMS memu. Additionally, you may want to modify the following values in the preferences :
- cache.wmsplugin.expire -1 : this is a time in second until the tiles are invalidated. -1 means "never flush".
- cache.wmsplugin.maxsize 999999999 : maximal size of the cache (probably in MB)
Even though you have to download an area "manually", you can work offline using this technique.
Using a "Rectified Image"
Do not use copyrighted material, unless you have the right/permission to do so (see the Licensing section below)!
Before you start with your own images, it might be a good idea to start with Landsat data so you'll learn how to work with these downloaded images.
To work with your own images in JOSM:
- upload your aerial image / scanned old map to either
- MapWarper at http://mapwarper.net/ or
- MetaCarta at http://labs.metacarta.com/rectifier/
- Note: please read their privacy/copyright notes first
- rectify it on their site so it "fits with reality"
- XXX - wait for the image to be processed?
- remember the metacarta id (look at the URL in your browser)
- in JOSM, load some openstreetmap data of the expected image area (to be in the right "clipping range")
- click on WMS -> Rectified Image and enter the id in the upcoming dialog
If the "clipping range" was wrong, you might see just nothing. In this case zoom out and retry the download.
Adding a WMS Server
Do not use copyrighted material, unless you have the right/permission to do so (see the Licensing section below)!
To add a new WMS Server, use the Menu: 'Edit' menu -> 'Preferences' and click on the WMS tab. Now you can add / remove WMS server URL's.
A WMS server typically can provide different projections, subsets of data, etc., so you may need to experiment with the URL settings to get the best results.
Adding presets for objects and source=yahoo_wms
It can be useful to let other users know what your data is based on by adding source=yahoo_wms. This can be quickly done by creating a JOSM tagging preset for roads, woodland, etc and source=yahoo_wms.
Once this is setup, it is simple to apply custom combinations of tags to an node, way or area in JOSM:
<annotations> <item name="road-source" icon="[PATH TO ICON]\Yahoo-road.png"> <key key="source" value="yahoo_wms" /> <key key="highway" value="road" /> </item> </annotations>
- Save it as yahoo-presets.xml
- Open JOSM
- Open the Preferences, go to the Map Settings (3rd tab)
- Add your file at the "Tagging Preset Sources"
- Restart JOSM
- If you want, you can put the preset in your toolbar for quick access (Preferences, Toolbar customization)
- You might also want presets for things like landuse=farm and/or waterway=stream
- Download the above icons and add new <item> entries to your yahoo-presets.xml file
- Contact User:LeedsTracker if you want any more icons made --LeedsTracker 17:04, 28 February 2009 (UTC)
Remote control
Since version 22677 the WMSPlugin will register an additional remote control command "wms" if the RemoteControl plugin version 22675 or newer is loaded.
The "wms" command instructs JOSM to open a WMS layer in the same way as with the "rectified image" menu command.
GET /wms?title=foobar&urldecode=false&url=...
|WMS URL in the usual format. This must be the last parameter.
|Title (name) of WMS layer. If not specified the title will be "remote WMS".
|Disable URL-decoding of URL value if true. All other values will be URL-decoded anyway.
|Can be used to specify cookies for the WMS request.
Note: The "url" parameter must be the last one. Everything after url= will be used as the WMS URL. It is not mandatory to URL-encode the value, but the WMSPlugin will try to URL-decode it unless urldecode=false is specified. If you notice that the decoding modifies the URL in an unwanted way, add "urldecode=false" before the "url" parameter.
This remote control function can be disabled by setting preferences value
or by using the checkbox "Allow remote control (reqires remotecontrol plugin)" in the preferences editor.
You MUST NOT trace over maps, aerial photography, or satellite images from any source, unless the images are public domain, or otherwise compatible with our OpenStreetMap License.
Tracing over an image is generally regarded to be creating a derivative work of the underlying image. This is also the case for aerial photographs as well as for (more clearly copyrighted) finished maps. If the images are copyrighted, or if you are unsure of the copyright status of the images, from a particular source, then you must not use those images for tracing/correcting maps for OpenStreetMap.
- Sources you can use
- NASA Landsat - Public Domain low resolution satellite imagery. Worldwide coverage, but generally too low-res for tracing roads or other such details.
- New Popular Edition - Out-of-copyright maps from 1950s or earlier from http://www.npemap.org.uk/ (UK only). Note that NPEmaps supplied as a WMS have not been as thoroughly rectified as those presented within Potlatch. This means you should not use NPE Maps within JOSM except as a rough guideline. When tracing over NPE maps use Potlatch for better accuracy.
- Provisional/First Edition - Out-of-copyright maps from 1950s or earlier from scans of First Edition Maps.
- Bing Aerial Imagery - Special Permission - We have been given special permission to derive our vector map data.
- Yahoo! Aerial Imagery - For a long time we've been allowed to derive our vector map data from Yahoo. It requires a special downloader component. Installation described above.
- De:DOP Sources - List of DOP sources for Germany and their status of permission to use in OSM
- New Jersey 2007 aerial photography. Only available within and slightly overlapping the borders of New Jersey. There are no restrictions on its use.
- OpenAerialMap: This is currently offline, but if/when this project is resuscitated it provides open aerial imagery compiled from many sources/imagery donations.
- WikiProject_Italy/PCN: Covering all of Italy with good ortho-rectification and far better resolution than Yahoo (please don't trace from Yahoo in Italy for this reason, as there is a big offset)
See WMS sources for more information.
- Sources you can't use
- Google map tiles - Copyrighted!
- Google aerial imagery - Copyrighted!
- Bing map tiles - Copyrighted! (we're only allowed to use the aerial imagery)
- Yahoo map tiles - Copyrighted! (we're only allowed to use the aerial imagery)
- Pretty much any other source which is not explicitly listed above

Motion controller can rejuvenate your machine
Your hydraulic machine's productivity is falling, your downtime and maintenance costs are increasing, and your machine has the shakes. What do you do? You could buy a new machine, or you could upgrade your PLC for more performance and redo your control software, but there's an alternative that you should look at: Consider adding an electro-hydraulic motion controller. (Updated Dec. 31 with more photos and motion-control diagram.)
Smoother motion
One of our customers, a chemical company, had a machine that compresses rubber crumbs into bales. The machine had a cover weighing several hundred pounds that would close over the bale during every compression stroke. To keep machine throughput high, the cover needed to close at a high rate of speed—between 20 and 25 inches per second. Originally, the hydraulic cylinder that opened and closed the cover was operated by the PLC using an on/off hydraulic valve. To avoid the hydraulic shock that would occur every time the cover of the machine would close the original machine designers installed cylinder cushions. When it became obvious that the cushions were wearing out quickly, causing maintenance problems, we added a proportional valve controlled by an analog amplifier to enable smoothing out of the motion.
When better precision and smoother accelerations and decelerations were required, it made sense to replace the amplifier with a programmable motion controller that could interface directly with the proportional valve. Even though the cover could close and open just as quickly as before, the smooth motion profiles cured the maintenance problems and extended the life of the machine, while achieving the level of precise positioning that was required.
Offload the PLC
As an alternative in cases where more precise closed-loop control is required, why not just add a PLC or upgrade the one that you have, and modify your application software to do a better job of controlling the motion? To do precise motion control, a PLC would need to be able to execute the appropriate mathematical algorithms during its scan time, along with other functions that it is responsible for managing. It is hard for PLCs to do motion control, however, because they typically do not have instruction sets that are tailored for this function, and machine scan times can vary from scan to scan, making it difficult to deal precisely with feedback information.
For example, one machine used hydraulics to close the die on an injection molding machine that makes 20-ounce plastic cups. The machine used a control output from a PLC to control a hydraulic valve, but the PLC didn't have the computing power to read a position transducer on the fly and change the valve setting to vary the rate at which the mold was closing, all within the PLC's scan time. As a result, the mold, which makes 100 plastic cups at a time and weighs more than 100 pounds, would close with a bang, risking damage to parts of the machine and causing an imprecise sealing of the mold cavity and sometimes resulting in the production of poor-quality cups that had to be scrapped. To solve the problem, an electro-hydraulic motion controller was added to the machine and the PLC program changed to produce two commands to the motion system: an output that says "close die" and one that says "open die." The motion controller was programmed to execute a profile that produces the appropriate acceleration and deceleration of the motion.
The motion controller, designed for high-performance calculation of motion algorithms, was an RMC controller from Delta Computer Systems of Battle Ground, WA. It has an instruction set tailored for closed-loop control of proportional servo valves, including the ability to use special gain terms in the control-loop equations called velocity and acceleration feedforwards that help optimize performance.
After we put the Delta motion controller in the system, keeping the old PLC, we were able to increase cycle rates and decrease shock. The large die sequence can now open and close smoothly in 1/3 second. This couldn't have been done with the existing PLC. Since the motion controller has the performance to produce complex motion profiles, a simpler, lower-performance PLC can be used in many applications that might have otherwise required a larger, more expensive, high-performance PLC in the past. The motion controller can control position and force if the proper transducers are supplied.
Machine retrofits
Sometimes the performance of a machine is limited by the need to coordinate the motion of multiple motion axes. The machine's output could be increased if the moving parts could move faster, but the old control system might not allow that. In another application, an old plywood veneer lathe included arms that held the ends of the log section (called a "block" in sawmill-speak), which needed to move in lockstep as the block was moved into place for peeling. Any lapse in coordinated control would allow the block to fall. With this in mind, the mill operator still wanted the machine to do its job more quickly.
Adding a controller to the lathe resolved the problem. Since Delta controllers can coordinate the motion of multiple motion axes simultaneously, the controller could move both arms of the machine, controlled as two discrete hydraulic axes, in synch without dropping the work piece. Additionally, through a process called gearing, the machine speed can change without losing the relationship between the axes in motion. This feature can also be very helpful for troubleshooting or responding to different production requirements or variability in raw materials.
Another sawmill application was a log kicker that needed to operate at higher speed. The kicker's arms are rotated to push logs that have been de-barked and cut to length into the sawmill to be cut to the desired widths. One log is transported into the mill for each half-turn of the arms. The machine was previously controlled by an old PLC to move the arms at a uniform speed, but the mill's operators saw that they could get higher throughput if they could swing the arms more quickly into position while they were not in contact with logs. Integrating a controller into the existing system added smooth accelerations and decelerations to the motion steps, and decreased cycle times, without changing the PLC or its software. This was possible because the RMC could communicate easily with the PLC—in this case using commands sent over an RS-232 serial interface.
Motion software support
Ease of use helps speed implementation. Some motion controllers require tedious programming with low-level machine instructions that make debugging and tuning of designs difficult. Other motion controllers are designed to be easy to program with high-level motion commands. So machine builders should examine the motion specs of a new controller and level of design support provided by the manufacturer. RMCTools by Delta Computer Systems includes helpful programs, such as the Curve Tool, that make motion profile development almost as easy as "point and click."
A Tuning Wizard shortens the time to optimize motion controller systems. Delta's tuning wizard automatically sets the motion controller's position control loop gains according to settings input using the graphical interface.
Distributed intelligence
As suggested above, adding a motion controller can improve controls of just the critical part of a machine. For this purpose, controllers are available that control a range of numbers of axes—from just one or two, up to eight axes or more.
If you're plugging in a new motion controller, it makes sense to network it to the PLC. Ethernet network interfaces, such as EtherNet/IP and Profinet, are less expensive to install and maintain than old point-to-point wiring techniques and can enable new capabilities.
Gain motion controller programming experience using a motion simulator before trying the control program on the actual machine. Some motion controllers are supported with a built-in simulator that provides the ability to test and debug programs at a desk before you do a site test. The Delta controllers' network interfaces can let you do remote monitoring and troubleshooting from your desk after the motion controller is installed. In the case where PLC replacement is needed, it may be more cost-effective to downsize PLC features and let the motion controller take a lot of what the PLC used to do. Several recently introduced low-cost PLCs are very effective for functions such as supervisory control, discrete actions, and alarming.
So if your old machine is starting to show signs of age, or it's not keeping up with the newer machines available, consider adding new life with motion controller retrofit.

GREENEVILLE, Tenn. --- Coker College combined to shoot an invitational-record score of 275 on Sunday at Link Hills Country Club to win the 16th annual Tusculum Men's Golf Invitational with a two-day score of 564, breaking the 36-hole invitational record by 15 strokes at Link Hills Country Club on Sunday.
A total of four teams posted a two-day score lower than the previous Invitational 36-hole record of 579, set by Tusculum at the 2006 event. Coker finished the weekend with a four-under-par score of 564 as Chris Marsh (Georgetown, SC) captured the individual title for the Cobras with a two-day total of 138 (-4). Coker's Jimmy Gillam (Tyrone, PA) had the low round of the day with a 66, tying the 18-hole individual invitational record.
Limestone College, the overall leader after day one, finished second with a two-day score of 570. Tusculum (574), Grand Valley State University (577) and Lincoln Memorial University (580) rounded out the top five. Spartanburg Methodist (593) finished sixth, followed by Brevard (594), Walters State (596), Mars Hill (596), Montevallo (600), Lenior-Rhyne (609), Tusculum Black (612), Tri-County (615), Tiffin (622), and USC Lancaster (630).
Behind Marsh and Gillam were John LaDow (Pottstown, PA) in sixth place with a two day total of 141 (-1), with Jared Crane (Greenville, SC) in 17th place with a 145 (+3), followed by Diego Polo (Guatemala City, Guatemala) in 25th place with a 147 (+5).
Coker will now prepare for their next tournament at the Bobcat Invitational, March 23-24 in Lake Oconee, Ga.
