1.2.3 User Connection
Functions of user connection
• The FP7 CPU Unit can open virtual communication lines for up to 16 connections with
Ethernet-supporting devices connected to LAN, and send/receive data.
• It can open multiple connections between the FP7 CPU unit and multiple nodes or a single
node, and execute communication.
• Operation mode, open method, protocol, etc. can be selected for each connection.

Connection operation
• Connection is opened from either the FP7 CPU unit side or the external device side.
• The open method should be selected from server connection (unspecified partner), server
connection (specified partner), and client connection, in the configuration menu of FPWIN
GR7.
• Once connection is established, communication by a user program becomes possible in
accordance with the operation mode.
