Good day everyone. I would like to ask something regarding PID Instruction. I noticed one of our machine's PID instruction status is showing "PID Initialize = NO". I am wondering if this can cause the PID not to function normally? And how to initialize it?
Reason for asking is because one of our older machines suddenly is unable to achieve the setpoint temperature. Is it controlled using the PID instruction. I went online tot he PLC and checked the rung condition are all OK and hardware side are also OK. Only noticed the PID instruction is showing "PID Initialize = NO". I have compared with our offline backup PLC program and noticed the PID Instruction status is showing PID Initialize = YES. Hence, I tried to download our backup program and everything is back to normal and now is showing PID Initialize = YES.
Thanks for your kind attention and stay safe.
