DPV1 Status Starting address of a 32-bit (2-word) produced range used to receive the station address
of a slave that has sent a DPV
1 Alarm message. If another slave sends a DPV 1 Alarm
message, it is ignored until the first one has been serviced, and will then appear in a
subsequent scan.
To acknowledge the DPV 1 Alarm message and obtain the alarm information it contains,
the application program can use a DPV 1 Alarm Acknowledge (task 9) COMMREQ.
The DPV 1 Acknowledge block must be a non-overlapping range in %AI, %I, %Q, %G,
%AQ, %R, %T, or %M. Defaults to %AI memory.
