Telecontrol communication - redundant paths
In this example an S7-1200 with a CP 1243-8 is connected to the master station via
redundant paths:
● One path via a dedicated line
● One path via the Internet
Other network combinations are possible.
As the master station TIM, a TIM 4R-IE is used here that uses the following interfaces:
● One Ethernet interface for connecting to the master station PC
● One Ethernet interface for connection to the Internet (via a SCALANCE M812 router)
● One serial interface for connection to the dedicated line modem MD2
The CP is connected via both interfaces:
● One Ethernet interface for connection to the Internet (via a SCALANCE M812 router)
● Serial interface with TS modules RS-232 for connection to the dedicated line
