Can there be multiple Master devices on a DNP 3.0 network?

Search KB


At this time, our InRAx line of DNP3 serial communications solutions offer 2 DNP serial ports. One will always be available as a DNP slave to provide data to a DNP serial master system. The other port may be used as a secondary, redundant DNP slave that has been connected to the same DNP3 master that is connected to the primary lave port; but connected on a separate physical serial network, as a way of providing redundant physical wiring paths between the our slave and the master.

This secondary port may not be used as a slave to a second DNP3 master, polling on an different network. However, it may be used as a DNP3 Master to poll other DNP3 Slave on a completely separate DNP3 physical serial network.
