Normal Serial Interface
This section explains how to set the required communications specifications
and the I/O format for using the Controller’s serial interface (with a RS-232C/
RS-422 connection or Ethernet connection) to communicate with an external
device, such as a personal computer.
Note
RS-232C/RS-422 and Ethernet connections cannot be used at the same time.
Use only one of these type of connections for the serial interface.
