Watlow Series PD - Manual (Page 165)

In sections 2.2.3 and 2.2.4 above, words 9 and 10 of the output assembly are
defined as AI_ERROR_ACK and ALARM_ACTIONS respectively. The definition
of the bits within those words follows:
As an example, the logic below uses simple bit level instructions to pick up and
annunciate the alarm 1 status in the event that it becomes active.
3.1.2 Explicit Messages - Ladder Logic Examples
Explicit messaging connections provide generic, multi-purpose
communication paths between two devices. These connections are often referred
to as just "messaging connections." Explicit messages provide the typical
request/response-oriented network communication. As an example of a read
Bit 00: 1 = Clear Latched Alarm #1 (tag_ALARM_LATCH_ACTION Instance 1)
Bit 01: 1 = Clear Latched Alarm #2 (tag_ALARM_LATCH_ACTION Instance 2)
Bit 02: 1 = Clear Latched Alarm #3 (tag_ALARM_LATCH_ACTION Instance 3)
Bit 03: 1 = Clear Latched Alarm #4 (tag_ALARM_LATCH_ACTION Instance 4)
Bit 04: 1 = Clear Latched Alarm #5 (tag_ALARM_LATCH_ACTION Instance 5)
Bit 05: 1 = Clear Latched Alarm #6 (tag_ALARM_LATCH_ACTION Instance 6)
Bit 06: 1 = Clear Latched Alarm #7 (tag_ALARM_LATCH_ACTION Instance 7)
Bit 07: 1 = Clear Latched Alarm #8 (tag_ALARM_LATCH_ACTION Instance 8)
Bit 08: 1 = Silence Active Alarm #1 (tag_ALARM_SILENCE_ACTION Instance 1)
Bit 09: 1 = Silence Active Alarm #2 (tag_ALARM_SILENCE_ACTION Instance 2)
Bit 10: 1 = Silence Active Alarm #3 (tag_ALARM_SILENCE_ACTION Instance 3)
Bit 11: 1 = Silence Active Alarm #4 (tag_ALARM_SILENCE_ACTION Instance 4)
Bit 12: 1 = Silence Active Alarm #5 (tag_ALARM_SILENCE_ACTION Instance 5)
Bit 13: 1 = Silence Active Alarm #6 (tag_ALARM_SILENCE_ACTION Instance 6)
Bit 14: 1 = Silence Active Alarm #7 (tag_ALARM_SILENCE_ACTION Instance 7)
Bit 15: 1 = Silence Active Alarm #8 (tag_ALARM_SILENCE_ACTION Instance 8)
