Figure 238: Overview of the pulse-counter logic function
The BLOCK and READ_VAL inputs can be connected to Single Command logics,
which are intended to be controlled either from the station HMI or/and the local HMI.
As long as the BLOCK signal is set, the pulse counter is blocked. The signal connected
to READ_VAL performs one additional reading per positive flank. The signal must be
a pulse with a length >1 second.
The BI_PULSE input is connected to the used input of the function block for the
Binary Input Module (BIM).
The RS_CNT input is used for resetting the counter.
Each pulse-counter logic function block has four binary output signals that can be
connected to an Event function block for event recording: INVALID, RESTART,
BLOCKED and NEW_VAL. The SCAL_VAL signal can be connected to the IEC
Event function block.
The INVALID signal is a steady signal and is set if the Binary Input Module, where the
pulse counter input is located, fails or has wrong configuration.
The RESTART signal is a steady signal and is set when the reported value does not
comprise a complete integration cycle. That is, in the first message after IED pickup, in
the first message after deblocking, and after the counter has wrapped around during last
integration cycle.
