Pulse counter logic (PC)
0HWHULQJ
Under EVENT MASKS/Analogue events/Pulse Counter in PST, 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
with the CAP configuration tool. A user defined name up to 19 characters long for each
pulse counter can also be set with the CAP configuration tool.
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 os-
cillating if the input frequency is greater than 40 Hz. The oscillation suppression is re-
leased at 30 Hz. From the PST under CONFIGURATION/Binary I/O-modules/
Oscillation in the terminal tree and from the local HMI, the values for blocking/release
of the oscillation can be changed.
