Table 5-58 Alternate Days Setup
Notes:
1)
The following table illustrates the data structure of the Date register:
When the Year and/or Month are set as
0xFF
, it means the Alternate Day is repetitive by year and/or month, i.e. the same day of
every year or every month is an Alternate Day.
Byte 3
Byte 2
Byte 1
Byte 0

Year-2000 (0-37)

DO 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 iMeter 6 does not support the Read Coils
command (Function Code 0x01) because DO Control registers are “Write-Only”. The DO Status register 0098
should be read instead to determine the current DO status.
The iMeter 6 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 (6185), 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
