MC Protocol Communication Function
(Note 5): The destination device address is specified by the combination of the low byte of [D1] and the value of [D2].
When the device address is in the range of H0 to HFFFF, specify "H00" for the low byte os [D1].
(Note 6): The devices that can be specified in [D3] is WX, WY, XR, WL, DT, and LD. They are stored as one word in a
specified area.
0: Normal end
1: Communication port is being used in the master communication.
2: The communication port is being used in the slave communication.
3: The number of master communication instructions simultaneously used is exceeded.
4: Transmission timeout
5: Response receive timeout
6: Receive data error

*1): Only when "direct addressing" in the MODBUS mode or MC protocol mode is set, integers can be specified for a
destination address.
 Flag operation
Name Description
Set in case of out-of-range values in indirect access (index modification).
Set when the source range is outside the accessible range.
Set when the slot number specified with UNITSEL is not [S1]=100 (built-in ET-LAN).
When there is not a connection that is specified with the UNITSEL instruction, the
connection is closed.
Latest error (SR7)
Set when the data device specified by S is incorrect or exceeds the area.
Hold error (SR8)
The number of sent data specified by n is incorrect.
The device code and the destination upper address specified by D1 is out of the range.
The destination lower address specified by D2 is out of the range.
The device in which results are stored specified by D3 is incorrect.
