The following tables describe the data structure for the IER Log for the Mains Meters, Sub-Meters and
Virtual Meters. The actual energy value is 0.1 times of the register value returned. Each request
packet can retrieve up to a maximum of 8 log records from the Mains Meter’s IER or 11 log records
from the Sub-Meter’s/Virtual Meter’s IER. For example, it’s possible to read
1.
8 records from Mains-I’s IER
2.
4 records each from Mains-I’s and Mains-II’s IERs
3. 1 record each from SM1’s to SM8’s IERs

5.8.10 Control Setup
5.8.10.1 DO Control
The PMC-592 adopts the ARM before EXECUTE operation for the remote control of its Digital Outputs.
Before executing an OPEN or CLOSE command on a Digital Output, it must be “Armed” first. This is
achieved by writing the value 0xFF00 to the appropriate register to “Arm” a particular RO/DO operation.
The DO will be “Disarmed” automatically if an “Execute” command is not received within 15 seconds
after it has been “Armed”. If an “Execute” command is received without first having received an “Arm”
command, the meter ignores the “Execute” command and returns the 0x04 exception code.
