4)Program

Specifying TC of channel to K type

Specifying TC input module SET data enable

Reading the digital conversion value of the TC input module to D0 and error information to D1.

If an error occurs at the channel 0 of the TC input module, M10 turns on.

If the channel 0 of the TC input module runs normally, auto processing is specified in the PID control module.

If an error occurs at the channel of the TC input module, manual processing is specified in the PID control module..

TC input module initialization

Reading the temperature- to-digital conversion value and Error detection

Using manual processing when an error occurs in the TC input module

Writing the digital conversion value of the TC input module as the PV of loop 0.
