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 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
