Serial Communication Function

This function communicates data using the MC protocol by connecting the RS-232 interface of the CPU module and a
personal computer or HMI from other companies with an RS-232 cable. This section describes the specifications,
functions, and settings of the function.
● A personal computer or HMI from other companies can communicate only with a CPU module connected to it. It cannot
communicate with stations connected over CC-Link IE, MELSECNET/H, Ethernet, or CC-Link.
● This function is not used to connect a programming tool or GOT to a CPU module.
● To execute this function with the Q03UDCPU, Q04UDHCPU, Q06UDHCPU, Q10UDHCPU, Q13UDHCPU,
Q20UDHCPU, or Q26UDHCPU, use GX Works2. (GX Developer does not support this function.)
