remote data is written
2. In general, use the MCONFP pulse instruction.
3. The following points explain the Modbus communication function codes in S
When the AS Series PLC reads the data from multiple bit devices (not discrete input devices), the function code
sent is 1 (16#01).
When AS Series PLC reads the data from multiple bit devices (only discrete input devices), the function code sent
is 2 (16#02).
When the AS Series PLC reads the data from multiple word devices (not input registers), the function code sent is
3 (16#03).
Name
Range: 16#05, 06, 0F, and 10.
If the function code is out of range,
outgoing parameters, including address
and data length, are not modified.
Range:16#0000–16#FFFF
Function code 16#0F for writing Bit device,
ranging from 1 to 256; the value in function
code 16#05 can only be 1; for PLC with
FW V1.06.20 or later: 0 can be used in
16#05
Function code 16#10 for writing Word
device, ranging from 1 to 100; the value in
function code 16#06 can only be 1; for
PLC with FW V1.06.20 or later: 0 can be
used in 16#05
When the setting value is 0 or less than 0,
this function is not enabled. If the setting
value is bigger than the maximum value, it
will be seen as the maximum value.
