Overview:

Performing control while changing the set point temperature moment by moment is called running a program pattern (or simply running a program). Sterilization and pasteurization require maintaining specific temperatures for specific durations. 

Industries:
You can determine the other 5 DI terminal numbers from the model code. -*2* means no. 301–306. The others (except -*4*) are no. 501–506. -*4* means 303–304, 309–310, and 503–504 are added.

Set junction code JC = HOLD. With this setting, it automatically enters the HOLD state when segments switch. Use operator determination to perform the ADV (advance) operation, and then move to the next segment.
If you perform auto-tuning while programs are running, the program time pauses, and then resumes after auto-tuning is done. (Note that auto-tuning fluctuates the output and PV.)
If you set JC=LOCAL, local operation status begins when the last segment of program operation ends. In this case, when zone PID (ZON=1,2,4) is selected, the PID group switches according to the selected zone. When segment PID (ZON=0) is selected, the ...
