When input BLOCK is ON, the function will ignore GI requests and cease allmonitoring activity. Consequently, no transitions will be detected.The I103POSCMD function is also equipped with two additional commands:Operate and Cancel. These are hidden in ACT and respond only to base INF +2and +3 respectively. The base INF (Information Number) parameter is an IEC60870-5-103 identifier that associates a function in a 103 Master (such as Scada)with its equivalent in the IED.4.2.5.2 Function block GUID-3A31C1F2-1FB5-4DB0-A698-AD3F55738DB1 v1IEC10000286-1-en.vsdI103POSCMDBLOCKPOSITIONSELECTIEC10000286 V1 EN-USFigure 17: I103POSCMD function block4.2.5.3 SignalsPID-6997-INPUTSIGNALS v1Table 43:I103POSCMD Input signalsName Type Default DescriptionBLOCK BOOLEAN 0 Block of status reportingPOSITION INTEGER 0 Position of controllable objectSELECT BOOLEAN 0 Select of controllable object4.2.5.4 SettingsPID-6997-SETTINGS v1Table 44:I103POSCMD Non group settings (basic)Name Values (Range) Unit Step Default DescriptionFunctionType 1 - 255 - 1 1 Function typeInfNo 160 - 236 - 4 160 Information number for command output4.2.5.5 Supported information typesIED commands with position and select for IEC 60870-5-103,I103POSCMD GUID-02A72231-F828-4B19-91A0-8AF3FE681A77 v5Number of instances: 50The function type for each function block instance is selected with the parameterFunctionType.The information number must be selected for the command output.1MRK 511 394-UEN A Section 4IEC 60870-5-103 vendor specific implementation670 series 2.2 IEC 47Communication protocol manual
