set_frequency (12)
The data frequency is set with the command set_frequency. The measurement data is
acquired with the data frequency and are ready to be transmitted via the interface (CANBus,
RS232, Bluetooth, GPRS, etc.) By setting the data frequency, the digital filter is set
automatically, see data frequencies and filter properties.
After executing the command “start_transmission”, the measurement data is transmitted
steadily at the set data frequency. After executing the command “stop_transmission”, the
measuring data is only sent when required. It can be requested with the command
“get_value” or for devices with CAN bus via CAN-Sync_ID (page 45).
Note: Care should be taken to ensure that the request for measured values does not occur
more frequently than the set data frequency. Otherwise, a current measured value will not
be available every time there is a request. The same measured values are requested
repeatedly.
