Section 16
Ethernet-based communication
for the specific access point. For information on how to activate the individual communication protocols,
see the communication protocol chapters.
The default gateway can be selected by entering the IP address in Default gateway. The default gateway
is the router that is used to communicate with the devices in the other subnetwork. By default this is set
to 0.0.0.0 which means that no default gateway is selected. ECT validates the entered value, but the
default gateway has to be in the same subnetwork as the access point. The default gateway is the router
that is being used as default, that is when no route has been set up for the destination. If communication
with a device in another subnetwork is needed, a route has to be set up. For more information on routes,
see the Routes chapter in the Technical manual and the Application manual.
DHCP can be activated for the front port from the LHMI in Main menu/Configuration /Communication/
Ethernet configuration /Front port/DHCP:1

16.2.2 Application
Dynamic access point diagnostic (RCHLCCH) is used to supervise and assure redundant Ethernet
communication over two channels. This will secure data transfer even though one communication
channel might not be available for some reason
Parallel Redundancy Protocol (PRP) and High-availability Seamless Redundancy (HSR) provides
redundant communication over station bus running the available communication protocols. The
redundant communication uses two Ethernet ports.

To increase security it is recommended to uncheck protocols that are not used on the
access point.
