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:
Logic 1 (Hi) if battery is low
Logic 1 (Hi) if there is a comm. failure to the operator interface
Logic 1 (Hi) if there is any operator panel unacknowledged alarm present
Logic 1 (Hi) if internal temperature is too high (>70C)
Logic 1 (Hi) if there is any operator panel alarm is present
Logic 1 (Hi) for one analog scan cycle after power up
Logic 1 (Hi) for one analog scan cycle after a new start of program (Program to Run)
Logic 1 (Hi) if a hardware fault is detected
Logic 1 (Hi) if a function block fails to operate properly
Logic 1 (Hi) when the controller run/program/test switch is in the test mode
Time controller was off (in sec.) after power loss (available for one analog scan cycle)
Analog function block scan cycle time in sec.
Analog function block scan cycle time in min.
