5.10 Remote Control
The DO Control registers are implemented as both “Write-Only” Modbus Coil Registers (0XXXXX) and
Modbus Holding Registers (4XXXXX), which can be controlled with the Force Single Coil command
(Function Code 0x05) or the Preset Multiple Hold Registers (Function Code 0x10). The PMC-512-D does
not support the Read Coils command (Function Code 0x01) because DO Control registers are “Write-
Only”.
The PMC-512-D adopts the ARM before EXECUTE operation for the remote control of its Digital
Outputs if this function is enabled through the
Arm Before Execute Enable
Setup register (6014), which
is disabled by default. 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” 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.
