field device that participates in the network acts as both a source of signal
and a repeater. Both redundancy and self-healing are provided by a wireless
mesh network, as every node has a connection to minimum one other node
and smart routing is used for identifying any other nodes, if its original
connection is lost. Thus, such ideal qualities for industrial applications make
this type of network a widely popular option in modern industrial automation
networks.
During the implementation stage, all the configurations of transmitters,
gateway and DeltaV serial communication card have been carried out
properly and the communication has been successfully established without
any alarms. Further, the process parameters have been manipulated
alongside simulating the loss of communication for monitoring the proper
activation of the alarm and all the data has been recorded. Another important
step of the job has been the development of necessary documentation such
as I/O list, BOM, Cause & Effect diagram, Electrical diagram, Interconnection
diagram, Instrument index and P&ID. Additionally, the work carried out has
been formed into separate parts with proper instructions for being included
as laboratory works in upcoming year’s course curriculum.
As a way of conclusion, the wireless mesh network based on
WirelessHART technology has been configured and tested at BHOS
Emerson test rig. The implementation steps and conclusions drawn have
been included in “Laboratory Work Instruction” document prepared for
contributing to bachelor curriculum.
