10.2 System Connection

What is System Connection?
System connection is the connection set without using the ladder program, and dedicated for the
programmable controller during computer link communication. For the system connection, three
connections can be used as well as the existing 8 connections (Connections 1 to 8).
Points:
For the connection that the auto open processing is executed, the auto open processing setting may be
-
ignored when the setup tool (Configurator ET) is used. On the other hand, the open processing setting
for the system connection is not ignored when Configurator ET is used. For this reason, the system
connection is suitable for communication with the PC tool "EPWIN-GR."
System connection can also be used for the communication method (TCP/IP or UDP/IP), open method
-
(Fullpassive or Unpassive), and the application using the connection (MEWTOCOL communication).

10.2.1 Initialization processing in the system connection

System connection can be used when the auto connection function is valid (Mode setting switch 2 is ON).
To use the system connection function, therefore, auto initialization processing setting is required.

10.2.2 Open processing in the system connection

Open processing procedures in the system connection are the same as the auto open processing,
except for the setting items and contents.
