Overview
The S8 series is equipped with two serial ports for RS-232C and RS-422/485 communication. You can connect two different
models of devices and allow the S8 series to communicate with them at the same time. This is called the 2-way
communication.
•
Only the logical port PLC1 can be selected for the following devices and functions. Thus, they cannot be connected at
the same time.
