Method for commissioning and joining of a field device to a network
First Claim
1. A method for commissioning and joining of a first field device to a wireless sensor actuator network in a process plant using a configuration tool, wherein the wireless sensor actuator network comprises a plurality of interconnected field devices and gateway for connecting the plurality of interconnected field devices to a plant automation network comprising a plurality of controllers and a network manager, wherein the configuration tool performs the method comprising:
- a) receiving device information associated with the first field device, wherein the device information comprises a unique device identifier associated with the first field device;
b) transmitting a commissioning request for the first field device, wherein the commissioning request comprises the received device information associated with the first field device, and geographical location information of the first field device;
c) receiving commissioning information for the first field device, wherein the commissioning information comprises a session key for pairwise communication between the first field device and the network manager, a network key for hop-to-hop authentication in a data link layer service by the first field device, and routing information corresponding to the first field device;
wherein the routing information comprises a list of neighboring field devices within a predetermined wireless communication range of the first field device, wherein the session key and the network key are generated based on the unique device identifier associated with the first field device, and wherein the list of neighboring field devices is generated based on the geographical location of the first field device and at least one of routing table and plant facility map; and
d) commissioning the first field device using the received commissioning information for joining the first field device to the wireless sensor actuator network.
