In order for the newly entered gateway channel and its parameters to also be known
to the gateway server xy, and thus also to make it available to other computers that
access this gateway xy, you must log into the run-time system. If you then re-open the
'Online' 'Communication parameters' dialog, the new channel appears in the „channel
tree“, not only in its previous position but also indented under the address or name of
the gateway server xy. This indicates that it is known to the network. You can now
open the Communication Parameter dialog on a computer other than the local one,
select gateway xy and use its new channel.
If a communications error occurs when logging in, it is possible that the interface
cannot be opened (e.g. COM1 for a serial connection) possibly because it is being used
by another device. It is also possible that the controller is not running.
The parameters for a channel already known by the gateway server can no longer be
edited in the configuration dialog. The parameter fields appear grey. You can,
however, delete the connection as long as it is not active.
Note!
Please not that the deletion of a channel is not reversible. It occurs at the moment
that you press on the button Remove !
