the input and all the outputs except the error output remains at zero state. The errorcondition remains until the correct settings for counter limits and/or initial valuesetting(s) are applied.The function can be blocked through a block input. During the block time, input isnot counted and outputs remain in their previous states. However, the counter canbe initialized after reset of the function. In this case the outputs remain in theirinitial states until the release of the block input.15.10.3.2 Reporting GUID-7DF874A7-F7DA-48DD-8760-5E4CF05FD870 v1The content of the counter can be read on the local HMI.Reset of the counter can be performed from the local HMI or via a binary input.Reading of content and resetting of the function can also be performed remotely,for example from a IEC 61850 client. The value can also be presented as ameasurement on the local HMI graphical display.15.10.4 Function block GUID-C90E7375-F3CC-414A-93FC-9AC4A9156FFC v1L4UFCNTBLOCKINPUTRESETERROROVERFLOWLIMIT1LIMIT2LIMIT3LIMIT4VALUEIEC12000029-1-en.vsdIEC12000029 V1 EN-USFigure 297: L4UFCNT function block15.10.5 SignalsPID-6966-INPUTSIGNALS v2Table 419:L4UFCNT Input signalsName Type Default DescriptionBLOCK BOOLEAN 0 Block of functionINPUT BOOLEAN 0 Input for counterRESET BOOLEAN 0 Reset of function1MRK 505 394-UEN A Section 15MonitoringLine differential protection RED650 2.2 IEC 601Technical manual
