PWM
and
pulse train
output use the same hardware configuration. Switching between
these modes is done within the SFB 49. Select via
‘Channel x’
the channel and select for
pulse train via
‘Operating mode’
the operating mode
‘Pulse width modulation’
. Default
values and structure of this dialog box depend on the selected
‘Operating mode’
. The fol-
lowing parameters are relevant for pulse train, which must be specified or determined:
1
Number of pulses
2
Period duration
3
Pulse duration
4
Pulse pause

Description
Assignment
Output format
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
Per mil
Time base
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
n
0.1ms: The time base is 0.1ms
n
1µs: The time base is 1µs
0.1ms
On-delay
This parameter is ignored.
