Technical manual
The Error output is activated as an indicator of setting the counter limits and/or initial
value setting(s) greater than the maximum value. The counter stops counting the input and
all the outputs except the error output remains at zero state. The error condition remains
until the correct settings for counter limits and/or initial value setting(s) are applied.
The function can be blocked through a block input. During the block time, input is not
counted and outputs remain in their previous states. However, the counter can be
initialized after reset of the function. In this case the outputs remain in their initial states
until the release of the block input.

Reporting

The 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 a measurement on
the local HMI graphical display.
