5.3.5 IP Addressing
Each IP-capable EPL node possesses an IPv4 address, a subnet mask and default
gateway. These attributes are referred to as the IP parameters:
Ipv4 Address
For an EPL network the private class C Net-ID
192.168.100.0
is used. A class C
network provides the IP addresses 1…254, which matches the number of valid EPL
Node-
ID’s. The Host-ID of the private class C Net-ID is identical to the adjusted EPL
Node-ID. Hence the last byte of the IP address (Host-ID) has the same value as the
EPL Node ID:
IP Address
192.168.100.

Host-ID

Subnet mask
The subnet mask of an EPL node is 255.255.255.0. This is the subnet mask of a class
C net.
Default Gateway
A default gateway is a node (Router/Gateway) in the EPL network and makes possible
the access to another network, outside of the EPL network.
The Default Gateway preset shall use the IP address 192.168.100.254. The value may
be modified to another valid IP address. If a Router/Gateway is present in the EPL
network, whose IP address is to be used.
The following table summarizes the default IP parameters:
