4. In the Trigger Type field, select the type of trigger associated with

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.
