Ethernet-based communication

When saving the ECT configuration after selecting a subnetwork, ECT
creates the access point in the SCL model. Unselecting the subnetwork
removes the access point from the SCL model. This column is editable
for IEC61850 Ed2 IEDs and not editable for IEC61850 Ed1 IEDs
because in IEC61850 Ed1 only one access point can be modelled in
SCL.
The IP address can be set in IP address. ECT validates the value, the access points
have to be on separate subnetworks.
The subnetwork mask can be set in Subnet mask. This field will be updated to the SCL
model based on the Subnetwork selection.
To select which communication protocols can be run on the respective access points,
check or uncheck the check box for the relevant protocol. The protocols are not
activated/deactivated in ECT, only filtered for the specific access point. For
information on how to activate the individual communication protocols, see the
communication protocol chapters.
To increase security it is recommended to uncheck protocols that are
not used on the access point.
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/
