Micromod Micro-DCI: 53MC5000 Multi-Loop Process Controller FLEXIBLE CONTROL STRATEGIES - Manual (Page 7)

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.
