rings, load transfer logics and so on. The graphical configuration tool ensures simple and fast
testing and commissioning.
Forcing of binary inputs and outputs is a convenient way to test wiring in substations as well as
testing configuration logic in the IEDs. Basically it means that all binary inputs and outputs on the
IED I/O modules (BOM, BIM, IOM & SOM) can be forced to arbitrary values.
Central Account Management is an authentication infrastructure that offers a secure solution for
enforcing access control to IEDs and other systems within a substation. This incorporates
management of user accounts, roles and certificates and the distribution of such, a procedure
completely transparent to the user.
Flexible Product Naming allows the customer to use an IED-vendor independent IEC 61850 model
of the IED. This customer model will be used as the IEC 61850 data model, but all other aspects of
the IED will remain unchanged (e.g., names on the local HMI and names in the tools). This offers
significant flexibility to adapt the IED to the customers' system and standard solution.
