Ethernet-based communication

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

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/Configuration/

Communication/Ethernet configuration/Front port/DHCP:1
