Hello,
I'm very new to PLC programming but working with Schneider Electric Unity Pro V13. I am trying to configure a legacy Momentum PLC 171CBU78090 (basic twin serial port PLC) on a ADO34000 base (16 digital outputs). The PLC is configured as a Slave, and is connected to a temperature alarm instrument that acts as Modbus Master, that writes to zonal alarm status bits. I'm just trying to program the slave to operate on zone status locations 10032,10033, 10034 and 11200 and to use those to activate relays on the outputs of the base. I unsure why I'm getting errors when building the system. Can anyone kindly show me the errors of my ways?
