the Trigger Tag address.
Trigger Type
Description
Bit
Trigger an alarm as it occurs. Multiple alarms can be triggered at once.
The bit position can be within:
•
a word (bit 0 to bit 15)
•
a block of consecutive words. Reserve up to 16 consecutive words (bit
0 to bit 255) after the tag address.
Each bit that changes from 0 to 1 will trigger an alarm whose trigger value
corresponds to that bit. The controller program must reset each bit (0)
after the corresponding alarm is displayed.
LSBit
(Least Significant Bit)
Trigger an alarm in a priority sequence (least significant bit to most
significant bit) based on its bit position within:
•
a word (bit 0 to bit 15)
•
a block of consecutive words. Reserve up to 16 consecutive words (bit
0 to bit 255) after the tag address.
The lowest order bit that changes from 0 to 1 will trigger an alarm whose
trigger value corresponds to that bit. Higher order bits are ignored until
the lower order bit is cleared by the controller program.
Value
Trigger an alarm based on a value at the Trigger Tag address. Trigger
values for alarms are defined on the Alarms tab.
Only one alarm can be triggered at a time for each trigger.
5. To add additional triggers, choose Append Trigger from the
