Control over WirelessHART Network through a Host Application: A WirelessHART Network Control Proposal

Abstract

The number of wires needed for effecting control increases with the complexity of the automation. In the last years, this has limited the development of process automation in the industry. Wireless networks offer an evolution to these restrictions, bringing facilities in reconfiguration and portability to mobile terminals. Meanwhile, some paradigms as, for example, security, reliability and latency, make it difficult for new technologies to be inserted into the industrial area. One of the major difficulties in wirelessly networked control systems is that the delay induced by the network in the control loop may cause degradation of the control performance and can destabilize the plant. This research offers a general view of the WirelessHART protocol for networked control systems, including the necessary mechanisms for an effective control loop through a host application. It also shows that is possible to perform control over WirelessHART networks with the control module placed in a host application using an acceptable working sample period for a process plant in a networked control system.

“…WirelessHART was ratified by the HCF in September 2007 as the first open communication standard designed especially for process measurement as well as control applications as specified in the HART protocol specification revision 7.0 (Al Agha et al, 2009;Chen et al, 2014;Chung et al, 2015;Nobre et al, 2014;Soto et al, 2014;Petersen and Carlsen, 2011;Zhu et al, 2009;Song et al, 2008). WirelessHART is compatible with the IEEE802.15.4-2006 physical layer and operate at the 2.4GHz frequency band with 15 channels (Kumar S et al, 2014).…”
