We have a MODBUS communication with a flow meter micro motion (Emerson), the communication is working, but sometimes stop the communicate. To return to communicate I change the parameter "Mod_CommdMax" to 0 and then return to 40 and normalizes. I am using the serial port, in controllogix and interface 1761-NET-AIC.
Could someone give a hint about this problem.

More information:
PLC: Controllogix ,
Software: RSLogix version 13;
Serial port configuration: 19.2k
Serial adapter: Rs232 to Rs485 1761-NET-AIC
