Figure 575: 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.
The BLOCKED signal is a steady signal and is set when the counter is blocked. There are two
reasons why the counter is blocked:
• The BLOCK input is set, or
• The Binary Input Module, where the counter input is situated, is inoperative.
The NEW_VAL signal is a pulse signal. The signal is set if the counter value was updated since last
report.
Note, the pulse is short, one cycle.
