Section 17 Ethernet-based communication17.1 Access point17.1.1 Application GUID-2942DF07-9BC1-4F49-9611-A5691D2C925C v1The access points are used to connect the IED to the communication buses (like thestation bus) that use communication protocols. The access point can be used forsingle and redundant data communication. The access points are also used forcommunication with the merging units and for time synchronization usingPrecision Time Protocol (PTP).17.1.2 Setting guidelines GUID-CEDC23B1-09F6-4C85-98D8-9D8E2C2553FE v2The physical ports allocated to access points 2–4 have to be addedin the hardware tool in PCM600 before the access points can beconfigured. The factory setting only includes the physical portsallocated to the front port and access point 1.The settings for the access points are configured using the Ethernet configurationtool (ECT) in PCM600.The access point is activated if the Operation checkbox is checked for therespective access point and a partial or common write to IED is performed.To increase security, it is recommended to deactivate the accesspoint when it is not in use.Redundancy and PTP cannot be set for the front port (Access point 0) as redundantcommunication 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. SCLsubnetworks can be created/deleted in the Subnetworks tab of IEC 61850Configuration tool in PCM600.When saving the ECT configuration after selecting a subnetwork,ECT creates the access point in the SCL model. Unselecting thesubnetwork removes the access point from the SCL model.
