5.12 ASYS Function Block

Description
The Analog System Status Block (ASYS) is a function block and is part of the Alarm/Monitor category. It
provides read access to controller status values including those related to the Analog execution cycle. The
output may be connected to function block inputs. The outputs may also be connected to signal tags for
operator interface monitoring. The ASYS System Monitoring block is assigned block number 249. It looks
like this graphically on the Control Builder:
