Here the interrupts, the counter function should trigger, may be selected. You have the
following options:
n
None: There is no interrupt triggered.
n
Process: The counter component triggers a hardware interrupt.
n
Diagnostics and Process: With the CPU the diagnostic interrupt of the digital in-/
output periphery is only supported in connection with "hardware interrupt lost".
There are no interrupts with the pulse width function.
The following parameters are relevant for pulse width modulation. Parameters, which are
not listed here, are ignored by the CPU.
1
Period duration
2
ON delay
3
Pulse duration
4
Pulse pause
Output format
n
Here select the range of values of the output value. With this the CPU calculates the
pulse duration:
Output format
Range of values
Pulse duration
Per mil (Default)
0 ... 1000
(Output value / 1000) x Period duration
S7 analog value
0 ... 27648
(Output value / 27648) x Period duration
Time base
n
Set the time base, which is valid for resolution and the range of values of period dura-
tion, minimum pulse duration and on-delay.
n
If you have checked the "1ms" button times with a resolution of 1ms can be set.
n
If you have checked the "0.1ms" button times with a resolution of 0.1ms can be set.
n
Default: "0.1 ms"
On-delay
n
Enter a value for the delay time between the start of an output sequence and the
output of the pulse. The pulse sequence is output on the output channel after the on-
delay has expired.
n
Range of values: 0 ... 65535ms respectively 0 ... 6553.5ms
Period (Period duration)
n
With the period duration the length of the output sequence (pulse duration/pulse
pause) is defined
n
Range of values: 1 ... 65535ms respectively 0.4 ... 6553.5ms
n
Default value: 20000
