I am trying to get a TSX P57 2634M to be a Modbus slave. The existing master will be comunicating to the PLC through a TSX SCP 111 PCMIA card. I have the card installed and its function set up as 'Modbus JBus Link'. What else do I need to do to get the PLC to act as a modbus slave? What sort of addressing do I need? Are there any function blocks I need to use? etc...
