IBase: Phase current value to be used as a base value for applicable functionsthroughout the IED.SBase: Standard apparent power value to be used as a base value for applicablefunctions throughout the IED, typically SBase=√3·UBase·IBase.18.8 Signal matrix for binary inputs SMBI SEMOD55793-1 v218.8.1 Application M15310-3 v2The Signal matrix for binary inputs function SMBI is used within the ApplicationConfiguration tool in direct relation with the Signal Matrix tool. SMBI representsthe way binary inputs are brought in for one IED configuration.18.8.2 Setting guidelines M15312-3 v3There are no setting parameters for the Signal matrix for binary inputs SMBIavailable to the user in Parameter Setting tool. However, the user shall give a nameto SMBI instance and the SMBI inputs, directly in the Application Configurationtool. These names will define SMBI function in the Signal Matrix tool. The userdefined name for the input or output signal will also appear on the respectiveoutput or input signal.18.9 Signal matrix for binary outputs SMBO SEMOD55215-1 v218.9.1 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.18.9.2 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.Section 18 1MRK 504 169-UEN ABasic IED functions346 Transformer protection RET650 2.2 IECApplication manual
