The counter stops counting the inputand all the outputs except the error output remains at zero state. The error conditionremains until the correct settings for counter limits and/or initial value setting(s) areapplied.The function can be blocked through a block input. During the block time, input is notcounted and outputs remain in their previous states. However, the counter can beinitialized after reset of the function. In this case the outputs remain in their initialstates until the release of the block input.12.3.3.2 ReportingThe 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, forexample from a IEC 61850 client. The value can also be presented as a measurementon the local HMI graphical display.12.3.4 Function blockL4UFCNT function blockL4UFCNTBLOCKINPUTRESETERROROVERFLOWLIMIT1LIMIT2LIMIT3LIMIT4VALUEIEC12000029-1-en.vsdIEC12000029 V1 EN1MRK 511 287-UEN A Section 12Monitoring425Technical manual
