Technical reference manual
The BLOCK and READ_VAL inputs can be connected to Single Command
blocks, 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 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 start-
up, 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.
The SCAL_VAL signal consists of scaled value (according to parameter Scale),
time and status information.
