Configuring the Local/Partner connection path
After inserting a TSEND_C, TRCV_C or TCON instruction into the user program, the
inspector window displays the properties of the connection whenever you have selected any
part of the instruction. Specify the communication parameters in the "Configuration" tab of
the "Properties" for the communication instruction.

TCP, ISO-on-TCP, and UDP
Connection properties
For the TCP, ISO-on-TCP, and UDP Ethernet
protocols, use the "Properties" of the instruction
(TSEND_C, TRCV_C, or TCON) to configure the
"Local/Partner" connections.
The illustration shows the "Connection
properties" of the "Configuration tab" for an ISO-
on-TCP connection.
Note
When you configure the connection properties for one CPU, STEP
7 allows you either to
select a specific connection DB in the partner CPU (if one exists), or to create the connection
DB for the partner CPU. The partner CPU must already have been created for the project
and cannot be an "unspecified" CPU.
You must still insert a TSEND_C, TRCV_C or TCON instruction into the user
program of the
partner CPU. When you insert the instruction, select the connection DB that was created by
the configuration.
