What is the use of the two data line interfaces of Omron plc?

There are two data line interfaces on the OMRON CJ or CS series PLC, one is the 9-pin RS232 serial port, and the other small port is the OMRON dedicated interface. The Chinese name is the peripheral port. Generally, the small port is used to connect the OMRON-specific programming cable. In addition, the small port can also be converted to RS232 serial port or 485 or 422 port through the converter to adapt to various communications.

For the data line, the serial port can define the production data line by itself. Small mouth RS232 port is CS1W-CN226
