How to Access Custom Alarm Status and Counters on PowerLogic PM5580

The PowerLogic PM5580 meter supports up to five custom alarms that can be configured for specific conditions. Users often need to monitor:

• Whether a custom alarm is active or inactive in real time.
• The accumulated activation count for each custom alarm.

This article explains which Modbus addresses to poll for these values.

1. How do I check if a custom alarm is active or inactive?

For the PM5580, the active/inactive state of the 5 Custom Alarms is available through the Coils associated with register 2427:

• Coil 38832 → Custom Alarm 1 (bit 0 of 2427)
• Coil 38833 → Custom Alarm 2 (bit 1 of 2427)
• Coil 38834 → Custom Alarm 3 (bit 2 of 2427)
• Coil 38835 → Custom Alarm 4 (bit 3 of 2427)
• Coil 38836 → Custom Alarm 5 (bit 4 of 2427)

The bit value will be 0 if the alarm is not active and 1 if the alarm is active.

2. How do I read the custom alarm counters?

The counters for each Custom Alarm are available via Modbus at the following registers:

• 13563 – Custom Alarm 1 Counter
• 13564 – Custom Alarm 2 Counter
• 13565 – Custom Alarm 3 Counter
• 13566 – Custom Alarm 4 Counter
• 13567 – Custom Alarm 5 Counter

These registers store the accumulated number of times each custom alarm has been triggered.

Summary:

• Use register 2427 / coils 38832–38836 for real-time active/inactive state of the customer alarms
• Use registers 13563–13567 for Custom-Alarm counters
