Hi everyone !
 Firstly I am new to PLC and i have knowledge of electrical control .
Now i am start learning plc with Omron PLC (CJ1M-CPU11).
Can anyone please help to advise and guide me how to read from one temperature sensor ( not OMRON ) , the address is set to 1. data type is holding register ( 0) for humidity and  1 for temperature.
I want to read from Omron PLC CJ1M +SCU 41-v1( Version) to that sensor.
Please help me to achieve.
Thanks a lot

Using Modbus RTU ( RS-485) , PORT 1 of SCU . I have tried that sensor using SCADA and it was successful. I have tried of SCADA and PLC ( SCADA as master and PLC as slave. I have set SCU to Modbus Slave) successful as well.

I don't know how to use PLC as master and temperature as slave via MODBUS RTU ( RS 485- 2 wire ).
