Basic IED functions

This is an advantage since all applicable functions in the IED use a single source of base

values. This facilitates consistency throughout the IED and also facilitates a single point

for updating values when necessary.

Each applicable function in the IED has a parameter, GlobalBaseSel, defining one out of

the twelve sets of GBASVAL functions.

Setting guidelines

VBase: Phase-to-phase voltage value to be used as a base value for applicable functions

throughout the IED.

IBase: Phase current value to be used as a base value for applicable functions throughout

SBase: Standard apparent power value to be used as a base value for applicable functions

throughout the IED, typically SBase=√3·VBase·IBase.

Signal matrix for binary inputs SMBI

The Signal matrix for binary inputs function SMBI is used within the Application

Configuration tool in direct relation with the Signal Matrix tool. SMBI represents the way

binary inputs are brought in for one IED configuration.

Setting guidelines

There are no setting parameters for the Signal matrix for binary inputs SMBI available to

the user in Parameter Setting tool. However, the user shall give a name to SMBI instance

and the SMBI inputs, directly in the Application Configuration tool. These names will

define SMBI function in the Signal Matrix tool. The user defined name for the input or

output signal will also appear on the respective output or input signal.
