Setups
The following chapter gives an overview over two scenarios with the EPL Gateway.
4.1
Variant 1 (No NAT)
This variant includes a PC with one network interface, EPL Gateway and MicroWeb Target2 with
I/O extension as CN. Please setup environment like following schematic:
To reach the EPL network a route to 192.168.100.0 over the Gateway has to be set on the PC.
NAT is deactivated so every node can be reached over direct IP access. EPL Gateway is also a
legacy router. If EPL is not active it should also be possible to reach all other nodes when they
are in basic Ethernet mode. In bigger networks the EPL Gateway has the IP address
192.168.100.254 (Router ID). This address is configured as standard gateway (DGW) on every
EPL device. The Gateway have to be part of the cycle as isochronous or asynchronous only
node. For this behavior set CNAssignment_AU32 (0x1F81) subindex 254 to 0x00000003 for iso-
chronous or 0x00000103 for asynchronous only accessed node. For additional information
please refer to EPL specification.
If you assembled installation above you should be able to see:
•
Intensive Ethernet Traffic on EPL segment (yellow traffic LEDs on Ethernet connectors flashing
fast).
•
Moving light on red LED bar of I/O module of CN 110 (only when Gateway contains standard
SND demo application)
From the PC you should now be able to:
•
Ping the legacy side of the Gateway via 10.0.2.15
•
Ping the EPL side of the Gateway (EPL MN) via 192.168.100.240
•
Ping the EPL CN via 192.168.100.110
•
Access the web interface of the gateway via 10.0.2.15
Attention
Do never Force both sides of the Gateway to default IP address. This will cause address conflict
and one side will shut down.
