Access point

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).
Setting guidelines
The physical ports allocated to access points 2–4 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.
The settings for the access points are configured using the Ethernet configuration
tool (ECT) in PCM600.
The access point is activated if the Operation checkbox is checked for the
respective access point and a partial or common write to IED is performed.
To increase security, it is recommended to deactivate the access
point when it is not in use.
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.
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
Ethernet-based communication
