Principle of operation

The Signal matrix for mA inputs (SMMI) function, see figure 37, receives its inputs
from the real (hardware) mA inputs via the Signal Matrix Tool (SMT), and makes
them available to the rest of the configuration via its analog outputs, named AI1 to
AI6. The inputs, as well as the whole block, can be tag-named. These tags will be
represented in SMT.
The outputs on SMMI are normally connected to the IEC61850 generic
communication I/O functions (MVGGIO) function for further use of the mA signals.
