Section 22
Basic IED functions
Signal Matrix tool. The user defined name for the input or output signal will also appear on the
respective output or input signal.
22.9 Signal matrix for binary outputs SMBO
22.9.1 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.
22.9.2 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.
22.10 Signal matrix for mA inputs SMMI
22.10.1 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.
22.10.2 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.
22.11 Signal matrix for analog inputs SMAI
22.11.1 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).
