8.1 Communication Instruction
[S1]：
Transfer in
word units
[S1]：
Transfer in
bit units
(Note 2) To [S1+1], the following specification should be applied.
COM port selection (upper four bits)
Port no.
(Note 3) 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.
(Note 4) Depending on the transfer method specified for operand [S1] and the device type specified for
operand [S2], the function code of MODBUS command to be sent varies.
Device type specified in
[S2]
16-Bit device:
WX, WY, WR, WL, DT, LD
1-bit device
X, Y, R, L
(Note 5) The area of the destination unit is specified by the combination of operands [D] and [n].
When [D] = DT0 and [n] = K100, the memory area of the destination unit starts with DT100.

Description
Turns ON when the [S1] / [S1+1] control data value is outside the specified range.
Turns ON when the [S2] or [D] area is exceeded, if the number of words specified in [S1] is
taken during transfer in word units.
Turns ON when [D]+[n] exceeds the [D] area
Turns ON when the COM port specification of control data specified in [S1+1] is not
MODBUS mode.
Turns ON when the [D] area is DT during transfer in bit units.
