TC input module
initialization
Specifying TC input module SET data enable
Specifying TC of channel to K type
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..
Using manual processing
when an error occurs in the
TC input module
Reading the temperature-
to-digital conversion value
and Error detection
Writing the digital conversion value of the TC input module as the PV of loop 0.
