5.7.3 ProceedingIn the Siemens SIMATIC Manager the following steps should be executed:1. Perform a hardware configuration for the CPU.Ä Chap. 4.5 ‘Hardware configura-tion - CPU’ page 692. 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 dialogbox with default values for this counter mode is created and shown. Select for thecorresponding channel the operating mode ‘Frequency counting’ .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 ofthe SFB are stored.5.7.4 Parametrization5.7.4.1 Address assignmentSub module InputaddressAccess DescriptionCounter 816 DINT Channel 0: Counter value / Frequency value820 DINT Channel 1: Counter value / Frequency value824 DINT Channel 2: Counter value / Frequency value828 DINT Channel 3: Counter value / Frequency valueSub module OutputaddressAccess DescriptionCounter 816 DWORD reserved820 DWORD reserved824 DWORD reserved828 DWORD reservedHardware configurationUser programVIPA System SLIODeployment I/O peripheryFrequency measurement > ParametrizationHB300 | CPU | 013-CCF0R00 | en | 19-30150
