I'm sorry Dave I have done next to no testing-I was hoping you could tell me! as per docs there is no parity used. speed and port must be set in config file to use the serial port . Have you tried this successfully with the original (not for emc) Classicladder? (I think I remember you saying you did..)
I assume you used something like this in your config file: MODBUS_MASTER_SERIAL_PORT=/dev/ttyS0 ###MODBUS_MASTER_SERIAL_PORT= MODBUS_MASTER_SERIAL_SPEED=38400 MODBUS_MASTER_SERIAL_USE_RTS_TO_SEND=0 MODBUS_MASTER_TIME_INTER_FRAME=200 MODBUS_MASTER_TIME_OUT_RECEIPT=500 MODBUS_MASTER_TIME_AFTER_TRANSMIT=0 When you open the config window do you see the (some) data you entered in the config file (under modbus distributed i/o heading)? Did you map the modbus address to an input/output variable? (done in the same window as above) I will try to help as much as I can -i'm working long night shifts right now...
