SYSTEM EVENT BLOCK

3-41

54

Global Acknowledge Input (GLBINP) ....................................................................... C – R

55

Diagnostic Acknowledge Input (DGINP).................................................................. C – R

56

Process Alarm Acknowledge Input (PAINP)............................................................ C – R

57

Notification/Requests Message Acknowledge Input (NMINP)............................... C – R
These acknowledge inputs are edge triggered so that a value of 0 (FALSE) followed by a
value of 1 (TRUE) acknowledges the alarm. Global acknowledge indicates all
diagnostics, process alarms and notification/requests are acknowledged.

None

No acknowledgement input connected.

LSP

Discrete variable used to acknowledge all alarms and reset the
input (not operator writable).
