When the number of sent data is odd, 4-bit
dammy code H0 is added.
● The amount of sent data [n] is specified in words for the register transfer and in bits for the bit
transfer.
● For the operand [D1], specify hexadecimal data that consists of the destination device code
and the device address of a partner unit.
Example) When the device code is 3 (internal relay) and the upper hexadecimal 2 digit of the
device address is H00, specify H300.
● For the "high byte of [D1]" that is the device code of the partner unit, specify one of the
following values.

● For the device address of the partner unit, specify six-digit hexadecimal (three-byte) data that
consists of the low byte of [D1] and the value of [D2]. When the device address is in the
range of H0 to H00FFFF, specify "H00" for the low byte of [D1].

Execution result code [D3]
Code Description Code Description
H0 Normal end H4 Transmission timeout
H1
The communication port is being used in the
master communication.
H5 Response reception timeout
H2
The communication port is being used in the
slave communication.
H6
Reception error
(Note 1)
H3
The number of master communication
instructions simultaneously used is exceeded.
H7
I/O allocation shortage error
(Note 2)
(Note 1) It occurs when an abnormal telegram is received. When there is a format error in the header of an
individual protocol, the communication discards the received data and a response reception timeout
occurs.
