Process Control Instructions

Rungs An additional group of PID instructions would cause the
16 – 21 STI to exceed its allowed limit (33 ms for a 50 ms
interrupt). This is the first four of a second group of eight
PID instructions. They execute on the opposite scan from
the first group of eight PID instructions so that the timing
limit is not exceeded.
Rungs The second four PID instructions of the second group of
22 – 27 PID instructions. They execute on the opposite scan from
the first group of eight PID instructions.
Figure 16.6 shows how you can simulate a manual control station. Locate
these rungs in the main program. This program will be used when the
functionality of a hardware manual control station is desired but manual
control separate from the controlling processor is not needed. It uses set
output mode to write the manual override output value to the
control device.
