The Bridge operating mode
In the Bridge operating mode, ETHERLINE
®
ACCESS NF04T behaves like a layer 2 switch between the machine
network (automation cell) and the production network. The IP addresses in the production network are in this case
in the same IP address space (subnet) as the addresses in the machine network.
Access between the two network
areas can be limited or secured
with packet filters and MAC
address filters.
This allows the separation of part
of the production network without
using different network addresses.
If “bridge” is your planned
application case, please continue
reading in chapter 7.
