On-line Monitoring and Diagnostics
Overview
On-line monitoring
On-line monitoring lets you test and debug the developed control strategy. It is not intended as an operator
interface. It allows a dynamic view of Function Block parameters in the controller using the Function
Block Diagram as a block selection aid. The changes do not affect the database file on the PC hard disk.
Additional controls on the live monitoring dialog box of Loop Control Function Blocks, such as PID,
ON/Off, TPSC, and Carbon, will handle Mode changes and Accutune initiation.
Diagnostics
The LCB provides live monitoring of Controller and I/O Module diagnostics. The instrument executes
diagnostic routines during instrument start-up and during on-line operation. This section includes tables of
status indications, possible cause, and actions to correct the problem.
