I have now and it works. I had the idea that it had something to do with codesyscontrol.cfg, but where can I find a description of all the things you can set in codesyscontrol.cfg and its syntax?

Thank you for your response. Is there documentation for the commands? I spent a lot of time trying to figure this out. I have a potato computer at home, so I'll have to test this later.

Hi ducng, you need to make sure that MC_Power.Status is TRUE before you give a rising edge to MC_MoveRelative.Execute. (This is the same for virtual and real axes). Best regards, Georg

Instead of using scaling of 150%, can't you adjust your diplay resolution (Windows+i keys, then go to System > Display settings)?

Hello, I have the same issue — some libraries aren’t resolved. When I load the libraries manually and delete them, reloading with the script works fine afterward. Have you found a solution since then? Many thanks in advance

Hello Julian, could you please check in Chrome Password Manager Settings if the option "Offer to save passwords" is set? With this option selected, a pop-up message will then show up asking whether or not to save the password. Choose OK. Hope this helps.

Post by yannickasselin on Lenze i950 Servo and WAGO PFC200 ^{CODESYS Forge talk (Post)}
In order to use SoftMotion Light, a servo drive needs to support CiA 402 operating modes: Profile Position (PP), Profile Velocity (PV) and Homing Mode (HM). https://content.helpme-codesys.com/en/CODESYS%20SoftMotion%20Light/_sm_light_requirements.html According to the Lenze i950 documentation you linked in your post, none of these modes are supported. Not even Homing Mode which explains why MC_Home does not work even with the full SoftMotion. The full SoftMotion uses Cyclic Synchronous Position Mode (CSP) but still uses Homing Mode (HM) when using MC_Home. You can monitor PDO 0x6060 (Mode of Operation). When using SoftMotion Light you will see it set to 1 (PP) for a MC_MoveAbsolute_SML and MC_MoveRelative_SML and to 3 (PV) for MC_MoveVelocity_SML and to 6 (HM) for MC_Home_SML. When using the SoftMotion instructions, it will pretty much always be set to 8 (CSP) except when using MC_Home, then it will be set to 6 (HM).

Post by ilya-vah on Table element issues ^{CODESYS Forge talk (Post)}
Hello, First post here. I would like to clarify whether the following behavior is known or if it is a bugs. Issue 1 — First row not displayed when using Maximum array index with 1-based arrays Description: When displaying data from an array that is indexed starting from 1 (e.g., ARRAY[1..N]), and the number of displayed rows is limited using the Maximum array index property, the first row of the array is not shown in the visualization. Steps to reproduce: Create an array indexed from 1 (e.g., ARRAY[1..N]). Bind the array to a Table element. Limit the number of displayed rows using the Maximum array index property. Run the visualization. Actual result: The first array element (index 1) is not displayed in the table. Issue 2 — Tooltip string placeholder cannot be bound to string variable from array Description: It is not possible to use a string placeholder in the tooltip that is bound to a string variable from the array. Steps to reproduce: Use a table bound to an array containing string variables. Configure a tooltip using a string placeholder referencing a string field from the array. Run the visualization. Actual result: Tooltip doesn't show any text. A test project demonstrating both issues is attached. Thank you for your time and support.
