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.
