Both communication partners execute the TCON instruction to set up and establish the
communication connection. You use parameters to specify the active and passive
communication end point partners. After the connection is set up and established, it is
automatically maintained and monitored by the CPU.
If the connection is terminated due to a line break or due to the remote communications
partner, for example, the active partner attempts to re-establish the configured connection.
You do not have to execute TCON again.
An existing connection is terminated and the set-up connection is removed when the
TDISCON instruction is executed or when the CPU has gone into STOP mode. To set up
and re-establish the connection, you must execute TCON again.
