The stepper supports CiA402 maybe I can use a CiA402 library to controll the stepper motor. Has anybody experience with that?

You could use the function AppGetApplicationInfo from CmpApp library. https://content.helpme-codesys.com/en/libs/CmpApp/Current/AppGetApplicationInfo.html

Post by bmatlove on Variable Length Array - Cannot mix variable and fixed length dimensions? ^{CODESYS Forge talk (Post)}
Using Codesys 3.5.18.30 I am trying to work with an array of variable length in one dimension, but known in the other dimension. For example, using an array that represents a list of items, each with an attribute profile. I do not know how many items will be in the list, but I know that every item has 5 attributes, like size, weight, etc. Codesys does not seem to be able to accept this. I have referenced Data Type: ARRAY OF documentation page, which is not explicit if variable & fixed length array dimensions can be mixed. In the VAR_IN_OUT scope, I initially tried MY_ARRAY : ARRAY [*, *] OF REAL; which was no problem, of course. I then modified it to MY_ARRAY : ARRAY [*, 1..5] OF REAL; which throws C0006: ', or ]' expected instead of '..' among consequent downstream errors. I then used the Auto Declare -> Array Wizard, which accepted (asterisk)-(asterisk) and 1-5 for 2-dimensional lower and upper bounds. It output: MY_ARRAY: ARRAY[*..*, 1..6] OF INT; which throws the same error stream. What's the deal here? Is this possible?

Post by paulpotat on cm4 runtime problem ^{CODESYS Forge talk (Post)}
Hello again, After looking into it, I noticed that the release note of "CODESYS Control for Raspberry PI 4.13.0.0" mentions a bug fix titled "Support Compute module 4". Is it possible to have more details about this fix from the CodeSys team please ? Because I have several CM4 boards with the same hardware revision / OS but some of them works with the 4.10 runtime and others only works with the 4.13 runtime...

Post by pixsys on Webvisu cliënt responsiveness ^{CODESYS Forge talk (Post)}
Hi, please check if "Support client animations and overlay of native elements" option is enabled. This option is very heavy to manage for the Webclients. I'm using the Pixsys srl "TC series" HMI with the code "P3" (so a 4+4 cores CPU) that runs very well also with this option active. The same CPU is mounted also in their WebPanel "WP" series, so you can try one of them if you want.

Post by alexgooi on Disable OPC-UA server ^{CODESYS Forge talk (Post)}
Dear Forum, I recently updated to the newest Codesys IDE (3.5 SP19 patch 5) The program wouldn't download cause of the amount of OPC-UA server tags (see picture) I'm not planning on using the OPC-UA server and therefore I unchecked the "Support OPC-UA features" checkbox in the symbol configuration. But this didn’t solve the issue of the OPC-UA server exceeding its license. How can I disable the OPC-UA server while still maintaining the symbol configuration. Thank you in advance Alex

Post by totorovic on Softmotion not working with simulation mode ^{CODESYS Forge talk (Post)}
Good morning, I think that the mode Simulation does not support the Softmotion functionnality because it runs the CODESYS process with normal priority wich is not a good thing for real-time behavior. If you want to test your PLC project, please use a Codesys Control Softmotion (and your computer must have the Ethercat driver installed) or much easier, download your code into the C6 Smart. BR

Post by timvh on Array to String ^{CODESYS Forge talk (Post)}
The string_Util_Intern is not the library I referred to. With a CONCAT function (also with the string util library) a search is done for the NULL character. If you concatenate 20000 characters to one string, then the longer the string, the longer it takes to find this NULL character.
