    This paper presents the design and implementation of condition monitoring for WirelessHART devices by using the supervisory control and data acquisition (SCADA) software called WW InTouch. The design of the proposed system is based on a concept of failure modes and effects analysis (FMEA) for creating the human machine interface (HMI) on the operator workstation. The implementation of the proposed system is based on a technique of WirelessHART-Modbus TCP data transfers by mapping the HART tag names from the field wireless devices to the Modbus registers in the WirelessHART gateway. The script functions running on the HMI for detecting the published diagnostic data of the monitored devices and for identifying the FMEA results of device and power supply failures are created. A WirelessHART temperature transmitter and a wired HART control valve positioner connected with Wireless THUM adapter are employed as the interested field devices for monitoring their abnormal operating conditions to verify the workability of the proposed system. Experimental results from the failure mimic show that the proposed system based on FMEA can function correctly.

    This paper presents a technique to integrate wireless field devices using WirelessHART and ISA100.11a technologies into a condition monitoring system based on Wonderware InTouch software. The proposed integration brings the data from a field site with digital multi-device networking for automatic data collection to support the condition monitoring of instruments or smart connected equipment in preparation of the Industrial Internet of Things (IIoT) implementation. Data including process variables and diagnostics from WirelessHART and ISA100.11a devices are buffered and mapped into Modbus/TCP registers for real-time monitoring at the operator workstation. Experimental results confirm that the proposed integration functions correctly.
