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 proj
ect
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.
