6.10.3.1 Configuration of the counter pulse length
Pulse length for counter can be configured on all eWON types.
The configuration must be entered in the eWON IO server edit area.
The following parameters are used:
Example of configuration:
MinInterval:40
MaxInterval:1000
ReverseCount:0
Counts pulse with length longer than 40 msec and shorter than 1000 msec, other pulses are ignored.
MinInterval: default=10, min=10
MaxInterval: default=268435455, max=268435455
MinInterval and MaxInterval are entered in milliseconds
ReverseCount: default=0
The pulse length must be between MinInterval and MaxInterval to be accepted, the measurement resolution is 5 msec (the
precision of the pulse length measured is 5 msec)
ReverseCount can be used if pulses entered in the eWON are reversed, reversed means that signal is normally high on the
eWON input and it goes low when the pulse occurs.
