Hi, I've the same problem. I want to pass a DB to the Modbus RTU master FB using SCL. I'm polling differnet slaves via a single instance of the FB and I need to address a different DB or DB variable for each salve. How can I do it? Is it possible by symbolic reference?

Maybe this could help: Recommended programming for S7-1200 and S7-1500 with STEP 7 (TIA Portal) V12 How do you create a PLC data type for an S7-1500 controller? How do you implement an array access with an S7-1200/S7-1500 with variable index? |
