HOWTO: Change frequency of 4Noks Devices

Last Updated: Jan 10, 2014 12:03PM CET

Modbus Commands (advanced users only)

To be able to change the frequency you need to the following messages:
  1. Read holding register 1 of the device.* 
  2. Write the new frequency (in seconds) to the holding register 1.
  3. Read holding register 1 of the device to verify that the change has been successful.
* Not really necessary but it is useful to check the connectivity with the device
