Post by konstantin on Lenze i950 Servo and WAGO PFC200 ^{CODESYS Forge talk (Post)}
Hello, basically the i950 drive support CiA402 Basic and CiA402 Advanced modes. I attached pictures of both mode supported functions. It also support CSP, VL, CSV and CST modes. It seems the homing mode is in CiA402 Advanced mode but how can you not have the homing mode in both modes? It is a vital part of any servo system. If I use the SoftMotion standard demo mode, I can move the servo absolute and relative but cannot home it. But in SoftMotion Light mode, I cannot execute any motion function. Here is the official manual for i950 servo drive - i950 Documentation Best Regards Konstantin Kolev

You actually can use copilot by PLCOpen XML file exporting/importing. It's fine to work with it directly (at least, the Codex do it quite well).

Post by konstantin on CAM Motion Recover after STO ^{CODESYS Forge talk (Post)}
Hello Mr. Seidel, both the master and the slave axis are modulo. Basically the situation is as follows: One master cycle is 100 units. Slave's modulo length is 2000 units. In the CAM table I defined 10 master cycles on X axis - 1000 units and on the Y axis is the slave - 2000 units. Then depending on the master position 0 to 1000 units the slave's position is plotted on the Y axis - 0 to 2000 units. For example, while the master is executing the 3rd cycle i.e. above 200 units, I trigger the STO function of the slave and it stops. The master executed his cycle but the slave was stopped during the execution. How can I set the slave to continue the CAM sequence from the point where it stopped i.e. third cycle of the master? When I reset the slave error and sync again, everyrhing starts from master's 0 position. Best Regards Konstantin Kolev

I don't have time to go through the whole manual but as I said earlier, the servo drive does not support any of the modes needed for SoftMotion Light to work. If you want to use the full SoftMotion, you could use SMC_Homing function block to do the homing. This function block does not use the Homing Mode. It still uses the CSP mode and does the logic in Codesys runtime instead of in the servo drive. Read the documentation about it to see if it fits your needs. But if your controller only supports SoftMotion Light, I am afraid you will not be able to use the i950. I do a lot of motion stuff with different servo brands. Some support all the modes needed for SoftMotion Light and some don't. You really need to make sure the modes are supported before choosing a brand over another. I tend not to use brand specific controllers in order not to be limited by their supported features. I usually choose a PC (Linux or Windows) and install the Codesys runtime and licences myself. This is the most flexible way to use Codesys in my opinion. Depending on how many axes are needed in your project, a full SoftMotion license may not be more expensive than SoftMotion Light because SoftMotion is available as Application based license whereas SoftMotion Light is not. But of course, SoftMotion is harder on the CPU than SoftMotion Light.

guess you'll need to use latest CODESYS version to fix this.

Issue with library updates ^{CODESYS Forge talk (Thread)}
Issue with library updates
Last updated: 2026-02-13

Post by fajean on Issue with library updates ^{CODESYS Forge talk (Post)}
We make heavy use of internally developed libraries, which are often nested on multiple levels. I routinely work simultaneously on several libraries along with a project that use them. I make changes to a library and immediately perform a download (online or otherwise) in the project. For the longest time, we had zero issue with this. But starting a good while back, with 3.5 SP19 I think, CODESYS started not noticing library updates in other instances most of the time. When the update is missed, the project sees no need to update the code, and any download ignores the new code. A "Clean all" does not solve the issue. But if I close and then re-open the project, then the new version is noticed and the download works. The other solution is saving the library to the registry multiple times (say, 20-30 times, less if lucky), and then at some point the project notices the changed library. I am now on SP21, and it is still not fixed. This is driving me mad, any tasks probably takes me double the time or more due to this problem. My colleague has the same problem on a separate computer. Is this a known issue? Is there a setting somewhere that changes how updates are checked? Thanks for any help!
