Hello All, I am attempting to perform Modbus tcp communication between a BRX plc and the ATV320, I have pinged from the plc so it knows the 320 is there, but when I perform a write or read the PLC doesn't show an error, but a success bit that should be getting set is not getting set. Attached below are the settings and setup, I was wondering if somebody has performed this communication with these two pieces of equipment before that could lend a hand? Thank you
