In the Siemens SIMATIC Manager the following steps should be executed:
1. Perform a hardware configuration for the CPU.
tion - CPU' on page 58
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. Select for the
corresponding channel the operating mode 'Frequency counting' .
'Counter operating modes' on page 104
4. Perform the required parameter settings.
5. Safe your project with 'Station è Safe and compile'.
6. Transfer your project to your CPU.
n The SFB 48 should cyclically be called (e.g. OB 1) for controlling the frequency meas-
urement.
n The SFB is to be called with the corresponding instance DB. Here the parameters of
the SFB are stored.

Via 'Basic parameters' you can reach 'Select interrupt' . Here you can define the inter-
rupts the CPU will trigger. The following parameters are supported:
n None: The interrupt function is de-activated.
n Process: The following events of the frequency measurement can trigger a hardware
interrupt (selectable via 'Frequency counting' ):
– End of measurement
Diagnostics and process: A diagnostics interrupt is only triggered when a hardware
n
interrupt was lost.
