Panasonic AFPX-C60R

7.3.3 1:N Communication (Computer Link)
Overview
For a 1:N computer link, the computer and the FP-X are connected through a commercially available
RS232C-RS485 converter, and the respective PLCs are wired using an RS485 cable.
The computer and the PLC communicate via commands and responses: The computer sends a
command specifying the unit number, and the PLC with that unit number sends a response back to the
computer.
Note) Lineeye SI-35 is recommended to be used as a converter.
