In PCM600 it is possible to set up a hierarchical structure of five levels for the IEDidentification.• Project• Substation = name of the substation• Voltage level = identifies to which grid type or part the IED belongs in the substation• Bay = bay within the voltage level• IED = the selection of the IED that is used in the bay; it is possible to insertseveral IEDs within a bay, for example, one control IED and two protection IEDs2.2 Standard configuration conceptThe product series covers IEDs developed for the protection of medium voltageapplications. Every product has predefined application-specific software calledstandard configuration that contains protection, control, supervision and measurementfunction blocks and default logical connections; for more information, see theapplication manuals. The product also includes the standard configuration specificdefault single-line diagram.The standard configuration software consists of connections between an application'sfunctions developed according to the needs of a particular functional application. Theinputs and outputs are similarly assigned to a default set of connections such asposition indication and Master trip. The alarm LEDs are assigned to defaultconnections based on the order number.Current and voltage channels for protection and measurement functionsare fixed as a part of standard configuration and cannot be reassignedwith Signal Matrix or Application Configuration in PCM600.The single-line diagram consists of an application-specific general arrangement of asingle-line diagram that includes position indications and the selection of controllableobjects and measurements.The content of the standard configuration depends on the intended functionalapplication. The standard configurations also have selectable software options, whichare selected when ordering the IED. Some of the software options are related to theIED hardware.The standard configurations can be used as is, but they can also be modified by usingthe PCM600. The standard configuration itself can be modified or extended by usingthe Application Configuration tool, the Signal Matrix tool and the communication1MRS240044-IB A Section 2IED engineering processREF615R 17Engineering Manual
