Compactlogix plx via modbus to durag flame controller, have other modbus slaves connected to plc working but can't figure this one out.
I have set it up for 19200 1 startbit 8 data bits, even parity, 1 stop bit. in my message block i've set it up so the first word is the node address, the next word is the function code, third word is the register to read from, and the fourth word the length of data. but i get embedded service error and sometimes connection fault any ideas? please help.
