21.7.4 Operation principle
The Signal matrix for binary outputs (SMBO) function , see figure 636, receives logical signal from
the IED configuration, which is transferring to the real (hardware) outputs, via the Signal Matrix
Tool (SMT). The inputs in SMBO are BO1 to BO10 and they, as well as the whole function block, can
be tag-named. The name tags will appear in SMT as information which signals shall be connected
between physical IO and the SMBO.
21.8 Signal matrix for mA inputs SMMI
21.8.1 Functionality
The Signal matrix for mA inputs (SMMI) function is used within the Application Configuration Tool
(ACT) in direct relation with the Signal Matrix Tool (SMT). See the Application Manual for
information about how milliamp (mA) inputs from external transducers are physically connected
to the MIM board inputs used in an IED. Via the SMMI, the signals are brought into the IED
configuration, for example, to the input for ambient temperature compensation of the thermal
overload function when there is a need for ambient temperature compensation in the thermal
function.
