24.9.1 Application
The Signal matrix for binary outputs function SMBO is used within the Application
Configuration tool in direct relation with the Signal Matrix tool. SMBO represents the
way binary outputs are sent from one IED configuration.
24.9.2 Setting guidelines
There are no setting parameters for the Signal matrix for binary outputs SMBO available
to the user in Parameter Setting tool. However, the user must give a name to SMBO
instance and SMBO outputs, directly in the Application Configuration tool. These names
will define SMBO function in the Signal Matrix tool.
24.10 Signal matrix for mA inputs SMMI
24.10.1 Application
The Signal matrix for mA inputs function SMMI is used within the Application
Configuration tool in direct relation with the Signal Matrix tool. SMMI represents the way
milliamp (mA) inputs are brought in for one IED configuration.
24.10.2 Setting guidelines
There are no setting parameters for the Signal matrix for mA inputs SMMI available to the
user in the Parameter Setting tool. However, the user must give a name to SMMI instance
and SMMI inputs, directly in the Application Configuration tool.
24.11 Signal matrix for analog inputs SMAI
24.11.1 Application
Signal matrix for analog inputs (SMAI), also known as the preprocessor function block,
analyses the connected four analog signals (three phases and neutral) and calculates all
relevant information from them like the phasor magnitude, phase angle, frequency, true
RMS value, harmonics, sequence components and so on. This information is then used by
the respective functions connected to this SMAI block in ACT (for example protection,
measurement or monitoring functions).
