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. 
The UP55A program controller comes standard with 8 contact input (DI) terminals, but I only know 3 of the terminal numbers.What are the other 5 terminal numbers?
(ns-faq-ut-2071-connect)
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.
At the end of UP32A/UP35A/UP55A programs, does the PIDNo. change when local is set (JC=LOCAL)?
(ns-faq-ut-2079-spec)
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 ...
How do I set up output of alarm output 1 from the UP32A/UP35A/UP55A AL1 terminals (relay contact output)?

That's correct. Also set the wait zone (WT.UP1–5, WT.LO1–5) and wait time (WT.TM1–5) accordingly.
With program controllers, can you do auto-tuning while programs are running?
(ns-faq-ut-2128-setting)

While a program is running, I want to judge advancing to the next segment with an operator. How can I do that?
(ns-faq-ut-2142-setting)
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.
I use the UP under batch control. I want to display a message on the front panel of the UP after batch control stops.

Can you tell me the procedure for assignment when the heater break alarm output option (suffix code /HA) is installed?
(ns-faq-ut-2015-setting)
Assignment settings are not necessary. The heater break alarm output has a dedicated output terminal.
Can I set up 4 alarm relay outputs?
(ns-faq-ut-2016-setting)

After changing the UT's SP values from the MELSEC via CC-Link, when I change the SP value on the UT main unit, I can't change to the same value as before from the MELSEC.
(ns-faq-ut-2026-connect)
As for individually writing parameters via CC-Link, changing OUT area values constitutes a write request. In your case, since the OUT area value hasn't changed from the previous value, the SP value is notoverwritten. As a fix, periodically copy t...
With CC-Link, I write 1 to RY48 and change to MAN, and then change to AUTO using the main unit A/M key. Can you tell me how to change back to MAN again via CC-Link?
