The package is configured and ready for direct use. Analog and control circuits
have been predefined and other signals need to be applied as required for each
application. The pre-configured IED can be changed and adapted to suit specific
applications with the application configuration tool.
The IED can be used in applications with the IEC/UCA 61850-9-2LE process bus
with up to four Merging Units (MU). Each MU has eight analogue channels, four
current and four voltages. Conventional input transformer module and Merging
Unit channels can be mixed freely in your application.
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 and IOM)
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.
The 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.

The following tables list all the functions available in the IED.
Those functions that are not exposed to the user or do not need to
be configured are not described in this manual.
