PWM
and
pulse train
output use the same hardware configuration. Switching between
these modes is done within SFB 49. In the Siemens SIMATIC Manager the following
steps should be executed:
1.
Perform a hardware configuration for the CPU.
Chap. 4.4 ‘Hardware configura-
2.
Double-click the counter sub module of the CPU 314C-2 PN/DP.
ð
The dialog
‘Properties’
is opened.
3.
As soon as you select the operating mode for the corresponding channel, a dialog
box with default values for this counter mode is created and shown. For
PWM
respectively
pulse train
output select for the corresponding channel the operating
mode
‘Pulse width modulation - PWM’
.
4.
Perform the required parameter settings.
5.
Safe your project with
‘Station

Safe and compile’
.
6.
Transfer your project to your CPU.
