24.9.1 Application SEMOD55213-5 v4The Signal matrix for binary outputs function SMBO is used within theApplication 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 SEMOD55228-5 v2There are no setting parameters for the Signal matrix for binary outputs SMBOavailable to the user in Parameter Setting tool. However, the user must give a nameto SMBO instance and SMBO outputs, directly in the Application Configurationtool. These names will define SMBO function in the Signal Matrix tool.24.10 Signal matrix for mA inputs SMMI SEMOD55233-1 v224.10.1 Application SEMOD55237-5 v2The Signal matrix for mA inputs function SMMI is used within the ApplicationConfiguration tool in direct relation with the Signal Matrix tool. SMMI representsthe way milliamp (mA) inputs are brought in for one IED configuration.24.10.2 Setting guidelines SEMOD55247-5 v2There are no setting parameters for the Signal matrix for mA inputs SMMIavailable to the user in the Parameter Setting tool. However, the user must give aname to SMMI instance and SMMI inputs, directly in the ApplicationConfiguration tool.24.11 Signal matrix for analog inputs SMAI SEMOD55751-1 v224.11.1 Application SEMOD55744-4 v10Signal matrix for analog inputs (SMAI), also known as the preprocessor functionblock, analyses the connected four analog signals (three phases and neutral) andcalculates all relevant information from them like the phasor magnitude, phaseangle, frequency, true RMS value, harmonics, sequence components and so on.This information is then used by the respective functions connected to this SMAIblock in ACT (for example protection, measurement or monitoring functions).1MRK 506 369-UEN B Section 24Basic IED functionsLine distance protection REL670 2.2 IEC 861Application manual
