3.12 Multicast pipe Manger
Previously it has been difficult to connect a single TCP device, i.e. a Scada / DCS system to multiple remote multicast
serial devices.
Multicast Pipe allows this type of connection.
Example:
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, i.e. 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, i.e. 5001.
