12.1 Frequency Measurement
12.1.1 FC 300 ... 303 - Frequency measurement SLIO consistent
The following VIPA specific functions are used to control the System SLIO frequency
measurement modules, which are connected via PROFIBUS, PROFINET or EtherCAT.
The usage with EtherCAT is only possible at an EtherCAT CPU from VIPA. By this func-
tions SFC 14 - DPRD_DAT respectively SFC 15 - DPWR_DAT for consistent read
respectively write access to the data are internally called. Error messages of these blocks
are reported by the parameter ERROR.
Function Symbol Comment
FC 300 FM_SET_CONTROL Function to control the frequency measurement with integrated
consistent access.
FC 301 FM_GET_PERIOD Function to calculate the period duration with integrated consistent
access.
FC 302 FM_GET_FREQUENCY Function to calculate the frequency with integrated consistent
access.
FC 303 FM_GET_SPEED Function to calculate the rotational speed with integrated consistent
access.
12.1.2 FC 300 - FM_SET_CONTROL - Control frequency measurement consistent
The System SLIO Frequency measurement module is controlled by the FC 300
FM_SET_CONTROL. By this function the SFC 15 - DPWR_DAT for consistent write
access of data is called. Here error messages of the block are reported by ERROR.
