3.13 Multicast Pipe Manager
Previously, it has been difficult to connect a single TCP device (such as a SCADA or DCS system) to
multiple remote multicast serial devices. Multicast pipe allows this type of connection. An example would
be a SCADA system that needs to communicate with multiple remote serial devices. A modem can be
placed at each remote location and connected serially to each device. A multicast pipe is configured to
communicate with all devices using a multicast address and port, for example, 224.0.1.1:5000. The SCADA
then communicates with the remotes using TCP via the IP address of the multicast manager and the port
selected in the configuration, for example, 5001.

Enables or disables the multicast pipe manager.
Server Port
Server port used by the multicast pipe manager. Will need to be configured the
same as the port on the client (for example, SCADA or DCS).
Multicast Group IP
Address
Broadcast address used when communicating to all other multicast devices.
This address will need to be the same on all communicating multicast devices.
Multicast Group Port
Multicast port used when communicating to all other multicast devices. This
will need to be the same on all communicating multicast devices.
