Sensor identification

MAC-Address:

Every sensor has to have a different proper and unique identification (unique ID), this is the MAC address or chain channel number (assigned by iMetos).

Chain_channel number:

The position of a sensor on the iMetos3.3 is identified by the chain_channel number. It is made up of the chain number and the channel number of the sensor.

The chain number is assigned according to the input connector:

            Chain 0 = Main sensors + HC2 + Duty sensors

            Chain 1 = Chain at input 1

            Chain 2 = Chain at input 2

            Chain 3 = Chain at input 3

            Chain 4 = Chain at input 4

            Chain 5 = Chain at dedicated input (RS485)

            Chain 6 = Extension board input A / Radio node sensors

            Chain 7 = Extension board input B

 

The channel number of any sensor connected to the PIbus is assigned according to the position of the sensor on the chain node and the proximity of the node to the iMetos. For RadioNode is assigned in chronological order of peering with the iMetos. The channel numbers of Chain 0 are given in the following table:

The chain_channel number is then calculated as

Chain number * 2000 + Channel number

Examples:

  • Wind speed sensor connected to WIND input: Chain = 0, Channel = 6 → Chain_channel = 6
  • First sensor of a chain connected to dedicated chain input: Chain = 5, Channel = 8

→ Chain_channel number = 10008
