Double Connection

Note

This configuration does work.

But it is senseless!

It is possible to configure a double connection between 2 stations using 2 separate networks (at least logically separated sub-networks).

However, such a setup has no advantages via-à-vis the minimal structure right at the start IEC60870-5-104 Multiple Connections.

For this setup, connection data must be double configured and double resources are also required at the stations, not providing any advantages whatsoever.

Rather the opposite is true, because such configurations are highly prone to errors.
