Your objective is to monitor an electric motor's temperature?  What is the driving force...prevent premature failure?  Is this an VFD-driven AC motor, a servo motor or a DC motor?  What type of thermocouple are you planning to use (i.e, Type J, Type K, etc.).

There are many, many ways you can get a thermocouple temperature to be displayed on the HMI.  You will need to be specific with the PLC processor platform, ControlLogix or CompactLogix.  There is a difference in I/O to bring the thermocouple into.

Your base choices are...standalone temperature measurement device with the thermocouple, or an RTD PLC module.

Dear kaiser_will.

thank for your feedback.

All motor don't using VFD to control, it direct control. 

All motor will add type PT100 temp sensor and send signal to plc via remote ( Ethernet or Modbus). we using compactlogix to get temperature.

pls advise if you have any experience for this.

many thank.
