Description
Here specify the range of values for the output. The CPU
hereby determines the pulse duration:
n Per mil
– Output value is within 0 ... 1000
– Pulse duration = (Output value / 1000) x Period
n S7 Analog value:
– Output value is Siemens S7 analog value 0 ...
27648
– Pulse duration = (Output value / 27648) x Period
Here you can set the time base, which will apply for resolu-
tion and range of values of the period duration, minimum
pulse duration and on-delay.
n 1ms: The time base is 1ms
0.1ms: The time base is 0.1ms
n
n 1µs: The time base is 1µs
Enter here a value for the time to expire from the start of
the output sequence to the output of the pulse. The pulse
sequence is output at the output channel, on expiration of
the on-delay.
Range of values: 0 ... 65535 from this there are the fol-
lowing effective values:
n Time base 1ms: 0 ... 65535ms
n Time base 0.1ms: 0 ... 6553.5ms
n Time base 1µs: 0 ... 65535µs
With the period you define the length of the output
sequence, which consists of pulse duration and pulse
pause.
Range of values:
n Time base 1ms: 1 ... 87ms
n Time base 0.1ms: 0.4 ... 87.0ms
n Time base 1µs: 1 ... 87µs
With the minimum pulse duration you can suppress short
output pulses and short pulse pauses. All pulses or
pauses, which are smaller than the minimum pulse dura-
tion, are suppressed. This allows you to filter very short
pulses (spikes), which can not be recognized by the
periphery.
Range of values:
n Time base 1ms: 0 ... Period / 2 * 1ms
n Time base 0.1ms: 2 ... Period / 2 * 0.1ms
n Time base 1µs: 0 ... Period / 2 * 1µs
