Pulse counter
The INVALID signal is a steady signal and is set if the Binary input mod-
ule, where the Pulse Counter input is located, fails or has wrong configu-
ration.
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 mes-
sage after terminal 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.
From SMS under the "Set Pulse Counter 1...12" menu, these parameters
can be set individually for each Pulse Counter:
• Operation = Off/On
• Cycle Time = 30s / 1min / 1min30s / 2min / 2min30s / 3min / 4min /
5min / 6min / 7min30s / 10min / 12min / 15min / 20min / 30min /
60min.
Under "Mask - Analogue Events" in SMS, the reporting of the analogue
events can be masked:
• Event Mask = No Events/Report Events
The configuration of the inputs and outputs of the Pulse Counter function
block is made by the CAP 531 configuration tool.
The appendix shows the parameters and their setting ranges.
On the Binary input module, the debounce filter time is fixed set to 5 ms,
that is, the counter suppresses pulses with a pulse length less than 5 ms.
The input oscillation blocking frequency is preset to 40 Hz. That means
that the counter finds the input oscillating if the input frequency is greater
than 40 Hz. The oscillation suppression is released at 30 Hz. From SMS
under the "Configure I/O-modules" menu and from the built-in MMI, the
values for blocking/release of the oscillation can be changed. Note that the
setting is common for all channels on a Binary input module, that is, if
changes of the limits are made for inputs not connected to the Pulse Coun-
ter, the setting also influences the inputs on the same board used for pulse
counting.
