Your function block instance is not called, so the code is not executed to set the light on when the button is pressed.

Hi Guys, I am new to this forum and i would like to ask od anyone got communication with Siemens v20 vfd working via Modbus RTU? I followed many websites and finally got the communication working but have problema with read/write registers. For example if i try to read holding register 40011 which is accel time i get noth but when i set the offset 0x0000 en length 113 i get ale the registers. I cannot get speed control working. I read someth about stw (control Word) and hsw but have some problems to understand it en get it working. It would be really nice if someone could help me with it. Thx

Post by trusty-squire on How can you get the active frame index from a frame ^{CODESYS Forge talk (Post)}
If you are switching a frame based on the "Switch Frame Variable", then just use a variable that is accessible to your program to set your active frame. If you're trying to see which is the active visualization, then use the "CurrentVisu" variable. Note you'll need to enable this by checking it on in the Visualization Manager settings. If it's neither of those, you'll need to be more clear on how you're project is set up.
