PID Loop
The PID Loop instruction executes a PID loop
calculation on the referenced LOOP based on the input
and configuration information in Table (TBL).
Error conditions that set ENO = 0: SM1.1 (overflow),
SM4.3 (run-time), 0006 (indirect address)
This instruction affects the following Special Memory bits:
