System Monitor Function Blocks

The HC900 Controller includes function blocks that enable the user to monitor the status of system
functions. When constructing a control configuration, consider adding the following monitoring function
blocks to the control strategy:
 ASYS – System Monitor
 FSYS – Fast System Monitor
 RK – Rack Monitor
 FMON – Fault Monitor
These function blocks are described in the HC900 Function Block Reference Guide #51-52-25-109.
