Efficient Querying of PLC2 Alarms Using ******* Calculation Tag Expression

Question:

Hello, I am interested in learning about a more efficient way to query alarm counts by PLC or area in *******. The support literature provided an example using the following syntax: \AlarmManager\GetAlarmStateStats([MQTT]\Root)\ActivePriorities["0002"]. In this example, MQTT is a context tag and an active priority of 2 represents a High priority alarm. I am looking to reference PLC2 alarms within the MQTT context tag, where PLC2 is a child of MQTT in the plant's PLC tree structure. Can someone provide guidance on how to query PLC2 alarms using the tree example: MQTT-PLC2-poll-all tags? Thank you.
