SIMEAS P MODBUS COMMUNICATION PROBLEM Currently I work with a SIMEAS P610 power meter(as a slave) and communicate to an Omron CP1H PLC (as a Master) through Modbus RTU , I tried to read data from meter with slave address=1, function code=3, baud rate=9600, parity=N, 1 stop bit etc. But no receive any response, I have read Modbus instruction manual of Simeas P and still can not find where is wrong, When this PLC communicates to an inverter with Modbus RTU, IT is working OK Could you please give me some advice? or example. |
