I'm trying to use a DirectLogic 05 as a Modbus RTU slave and control it over RS-232 using a .Net Program. I am using the nmodbus4 library.
The trouble is I can't get them to communicate. When ever I send it a command the serial port just times out. I tried this using Python and the minimalmodbus library with the same result.
Is there something I need to configure out the PLC to allow it to be used as a slave? the modbus is already enabled on the port. I can't find anything else that I need to configure in the manual.
