Section 19
19.1 Access point
19.1.1 Application
The access points are used to connect the IED to the communication buses (like the station bus)
that use communication protocols. The access point can be used for single and redundant data
communication. The access points are also used for communication with the merging units and
for time synchronization using Precision Time Protocol (PTP).
19.1.2 Setting guidelines
The settings for the access points are configured using the Ethernet configuration tool (ECT) in
PCM600.
The access point is activated if the
and a partial or common write to IED is performed.
Redundancy and PTP cannot be set for the front port (Access point 0) as redundant
communication and PTP are only available for the rear optical Ethernet ports.
Subnetwork shows the SCL subnetwork to which the access point is connected. This column
shows the SCL subnetworks available in the PCM600 project. SCL subnetworks can be created/
deleted in the Subnetworks tab of IEC 61850 Configuration tool in PCM600.
The IP address can be set in
separate subnetworks.
The subnetwork mask can be set in
based on the
Bay control REC670
Application manual
Ethernet-based communication
The physical ports allocated to access points 2–6 have to be added in the hardware
tool in PCM600 before the access points can be configured. The factory setting
only includes the physical ports allocated to the front port and access point 1.
Operation checkbox is checked for the respective access point
To increase security, it is recommended to deactivate the access point when it is
not in use.
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.
IP address . ECT validates the value, the access points have to be on
Subnet mask . This field will be updated to the SCL model
Subnetwork selection.
