Do you have a quick tip for pulling data out of the telegram 352 structure? I don't see it in an accessible PLC tag? I just want to get output current from the G120 and am interested in doing it via the telegram that the PLC to VFD is already using without adding a Sina_Para FB. It is using Sina_Speed for control and feedback, which is using telegram 352 for PN comms. So, I believe that I should already be getting output current feedback in there somewhere? Thanks, Chuck

Hi Chuck, easiest way to use telegram 352 is to use the SINA_SPEED_TEL352 function block from the LSinaExt library: https://support.industry.siemens.com/cs/de/en/view/109747655 It works the same way as the "normal" SINA_SPEED FB for tel 1. 2 hints for usage: - use the HW ID of the cyclic telegram 352 at the input parameter - configure the correct reference values for speed, current,... (see parameters p200x in the drive) |
Best regards, |
