Additional settings
This topology is a special instance of the Ethernet backbone with sub-loops, see Ethernet
backbone with sub-loops (Ethernet/CAN). You must operate one of the two loops as the
backbone.
Notice!
For all panels and switches in the backbone, set a higher RSTP priority than in the sub-loops.
This will ensure that the RSTP root bridge will always remain in the backbone, even in the
event of a fault.
The switches to connect the two loops are part of the backbone!
Use a RSTP priority of 16384 in the backbone.
Notice!
The lower the set value, the higher the RSTP priority.
Switches for connecting the OPC server and the second loop must be programmed
separately
Program the IP address and redundancy settings of the Ethernet switch, see Settings on
switch, page 39. For this topology, the fault outputs of the switch only have to be used if you
have designed the power supply for the switch redundantly, see Ethernet switch, page 51.
Make sure that the RSTP settings in the panel controllers, in FSP-5000-RPS and in the
Ethernet switch are identical.
Change the RSTP priority for the switches for connecting the two loops, as they belong to the
backbone.
OPC server must be programmed separately
Program the IP address, network nodes, network group and RSN. See the corresponding
section in the Installation chapter of the Networking Guide.
The OPC server uses port 25000 as standard.
Make sure that the settings in the FSP-5000-RPS programming software and in the OPC server
are identical.
Parameters
–
In these examples, loop a is the backbone. Loop b is the sub-loop.
07.2019 | 5.9 | F.01U.247.450
The OPC server may be connected via an Ethernet cable (copper) or fiber optic cable.
