Good Control Strategy
Development of good control strategy starts with a well-conceived plan. These few steps will help the user to
configure the PCC-IV in a timely manner:
•
Define the user’s requirements
•
Check the system Input/output (I/O) count
•
Break the configuration down into manageable sections
•
Drag the blocks needed for each section to the canvas
•
Assign block numbers and “Softwire” the Block Inputs
•
Modify Parameters as required
•
Add tags necessary for setting up the Panel Data Screen and/or OIT communication
•
Configure the front panel displays and alarms
•
Test the configuration
•
Place controller into operation
The remainder of this Section will be a detailed example of how to enhance a simple Boiler Master Blockware
Control Strategy by adding features in small manageable sections.
