Section G1 Introduction to Communication Modes

You can perform Ethernet communication with an external device by connecting a communication expansion board or
communication expansion unit to an SPF series CPU.
Each communication board and communication expansion unit has one physical port. Up to eight logical ports can be used per
physical port. However, if two or more ports are simultaneously used, responses of communication deteriorate.
For details, see "G1-2 Communication Port."
The following communication modes are available.
(1) General purpose communication
(2) Loader communication (server operation)
(3) Loader communication (client operation)

G1-1 Overview of Communication Modes

(1) General purpose communication
The "general purpose communication" mode allows data sending (or receiving) with external devices by TCP/IP or UDP/IP.
You need to create a communication program on the SPF side. Use "C_ETHERNET" FB.
