1.0 INTRODUCTION

1.1 OVERVIEW

The 53MC5000 Process Control Station (PCS) can be easily adapted to serve in a variety of con-

trol applications common to industrial processes. The PCS is usually adapted to a particular indus-

trial process by selecting the appropriate control strategy (CS) and by configuring the necessary

PCS datapoints.

In the event a required control strategy is not resident in the PCS, a new control strategy can be en-

tered into the PCS memory and executed, or a modified version of an existing one can be entered

and executed. This PCS functional versatility is called the Flexible Control Strategy (FCS) method.

With FCS, a fixed set of 41 modules can have their output signals selectively routed to each

other’s inputs. Not all of the modules in the set are alike; there are 15 different module types that

have specific functions. The module signal connections are first copied onto FCS worksheets to

build a wirelist before it is entered into the PCS and executed as a control strategy.

This instruction bulletin describes the FCS module types, the procedure to build a wirelist, and the

steps to execute the wirelist. It also provides four FCS examples.

It is recommended that the user first become familiar with the information and terms provided in In-

struction Bulletin 53MC5000, Process Control Station, before using this manual to design a Flex-

ible Control Strategy.

1.2 SCOPE OF BOOK

This instruction book is presented in three sections and two appendixes, briefly described as fol-

lows.

•

Section 1, Introduction

- Presents an overview of the Flexible Control Strategy (FCS) con-

cept.

•

Section 2, FCS Modules

- Describes the functional characteristics of each module in the

FCS repertoire.

•

Section 3, FCS Examples

- Provides four FCS examples.

•

Appendix A, Control Strategy Wirelists

- Provides a functional description, block diagram,

and completed wirelist for each of the ten resident PCS control strategies. This information

is provided in the event a modification is required to an existing control strategy.

•

Appendix B, Master Worksheets

- These are the master worksheets that are photocopied

and completed with the FCS module connections to create a wirelist that is actually entered

into the PCS.
