Specify the COM port No. of a master unit, send MODBUS command, and
S1
the unit number of a destination unit.
Specification of
S2
a master unit
Specification of
D
a destination unit
Specification of
n
a destination unit
(Note 1): In [S1], specify the combination of the COM port No. of a master unit, MODBUS function code and the unit
number of a destination unit. When the COM port No. is 0, specify HF for the highest digit.
Example: In the case of COM port 1, MODBUS function code 6, and destination unit No. 10, specify H160A.
[S1]：
COM port Command
(H1 / H2 / HF) (H5 to H6)
(Note 2): Depending on the operation memory type specified in operand [S1] and the number of send data specified
in operand [n], the transfer method and the function code of MODBUS command to be sent vary.
Device type
specified for [S2]
16-Bit device:
WX, WY, WR, WL, DT,
LD
1-Bit device:
X, Y, R, L
(Note 3): For the number of send data [n], specify the number of words in the case of register transfer, and specify the
number of bits in the case of bit transfer.
(Note 4): When "0" is specified for the destination unit number, global transfer is applied. In this process, there is no
response message from a destination unit.
