APPENDIX A: CONTROL STRATEGY
WIRELISTS
A.1 STANDARD CONTROL STRATEGIES
The wirelists for the ten control strategies of the 53MC5000 Process Control Station (PCS) are pro-
vided in this section. The resident control strategies of a PCS are option dependent: a one loop
PCS has 5 control strategies, CS1 - CS5; a two loop PCS has 8 control strategies, CS1 - CS22;
and a four loop PCS has 10 control strategies, CS1 - CS41. The wirelists for all 10 of these control
strategies are provided to expedite FCS generation — an existing control strategy wirelist that
most closely approximates the required application can be customized and entered into the FCS
datapoint locations. Even though the customized version of the standard control strategy is en-
tered into FCS datapoint locations B100 to B239, the original control strategy wirelist that was cop-
ied is not destroyed because it resides in the PCS Read Only Memory (ROM). It is therefore still
available to be invoked and executed by the PCS.
It should be noted that executing any standard control strategy will cause the FCS datapoint
wirelist assignment area (datapoints B100 to B239) to be overwritten, which would destroy
the customized version that was entered.
The control strategy wirelists, with associated block diagrams and brief functional descriptions are
provided in the order that follows:
CS1 — Single-Loop PID Controller
CS2 — Analog Backup Controller
CS3 — Ratio Controller
CS4 — Automatic/Manual Station
CS5 — Ratio Automatic/Manual Station
CS 20 — Two-Loop Controller
CS21 — Two-Loop Cascade Controller
CS22 — Two-Loop Override Controller
CS40 — Dual Two-Loop Cascade Controller
CS41 — Four-Loop Controller
