Analog input
Input variable x1 is converted into a number of pulses per hour. Parameter Puls/h is used for selecting the maximum
number of pulses at x1 ? x100. For x1 ß x0 no pulses are output.
Within range x0 - x100 , input value x1 is converted linearly into pulses per hour.
The parameter settings result in a straight line between 0 and 3600 pulses /h according to input x1The pulse length
corresponds to the sampling interval (100, 200, 400 or 800ms) adjusted for this block. The length of switch-off time be -
tween pulses is not always equal and dependent of the configured sampling interval.
The sampling interval allocation also determines the maximum number of pulses/hour, which can be realized. If higher
values than can be output due to the sampling interval are entered in parameter Puls/h, limiting is to the maximum
possible number of pulses.
Maximum number of pulses:
