Hi kenth1973, it is not a matter of who created the function block. It is just that we don't have, and don't provide, documentation about internal implementation details... Hope you can understand that, Georg

Hi gilad, I cannot tell for sure. But I think it should work on any PLC that is capable of doing motion control. Best regards, Georg

I did some work around by adding IN switch on top of OUT bulb picture(SwitchImage) and setting IN switch button to invisible but this is not quite elegant. How to combine it to one visu element?

Hello Tim, I am using CODESYS Visu V4.8.1.0. It works when I turn off the "Support client animation and overlay of native elements". But if I do that, dialog box moving and other options are also disabled so it is a bit problematic. Thank you for helping.

No that is not possible for function blocks, although it is possible to that with methods and functions as you see in your second pic.

Were you able to figure out if it is possible to change the Application/Product URI of your server? I am having the same problem.

Post by timvh on Alarmmanagement – Dynamic Alarm List ^{CODESYS Forge talk (Post)}
Probably best to create an alarm template for your motor function block. Then automatically the alarm manager can be filled with all the alarms for all instances of the motor function blocks (based on the created alarm template). See: https://content.helpme-codesys.com/en/CODESYS%20Visualization/_cds_obj_alarm_group_template.html

What do you think about having an AI Agent specialized in ST programming in Codesys? I see this saving hours and hours of work for those who program on a daily basis.

For whoever finds this old thread. Instead of System.exit(0), use system.exit(0) without capital 'S', this worked for me. I use these imports from future import print_function import sys import os

It's already fine to use, with help of exporting/importing as PLC_Open, at least CODEX is good in editing directly at XML and/or providing changes description separately.

Am I alone in this? Is this a known fault? Should I look for the reason of the lacking update option for "Control for linux SL" in my system or is it a potential fault in the codesys system?
