Serial Communication Function

This function communicates data using the MC protocol by connecting the RS-232 interface of the CPU module, the
RS-232 adapter, or the RS-422/485 adapter to the following devices.
• MC protocol-compatible devices
• Personal computer
• HMI from other companies
This section describes the specifications, settings, and details of the function.
Remark
The CPU module with the RS-232 interface and the LCPU where the RS-232 adapter or RS-422/485 adapter can be
mounted support this function. ( Page 376, Appendix 2)
● A personal computer or an HMI from other companies can communicate only with a CPU module connected to it, the RS-
232 adapter, and the RS-422/485 adapter. Communication with other stations in the network is not available.
● For details on MC protocol, refer to the following.
MELSEC Communication Protocol Reference Manual
● The RS-422/485 adapter can be used to connect multiple external devices (multidrop connection).
