5.8 DO Control
The DO Control registers are implemented as “Write-Only” Modbus Coil Registers (0XXXXX) and can
be controlled with the Force Single Coil command (Function Code 0x05). The PMC-53 does not
support the Read Coils command (Function Code 0x01) because DO Control registers are “Write-Only”.
Register 40066 (DO Status) should be read instead to determine the current DO status.
The PMC-53 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 DO operation.
The DO will be “Disarmed” 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.
