    System integration for process automation promoted the technologies that were accessed to functions and data of field device, controller, and SCADA system. In addition, the data from filed devices can apply to solve device diagnostic and preventive maintenance. This paper describes the practical technique to configure and implement of control and SCADA system that focus on integration of field device, PLC controller, and SCADA system. The paper presents case study of Allen-Bradley (AB) PLC by using WirelessHART device to temperature control and device diagnostic through SCADA system. PLC's input/output (I/O) modules are installed that consists of Modbus module, digital I/O module, analog I/O module. In addition, Prosoft configuration builder and Studio 5000 software are new software to build add on Modbus instruction and ladder diagrams, respectively. The experiments perform in case study of temperature control by using Proportional–Integral–Derivative (PID) function in the AB PLC. Wonderware InTouch SCADA software is implemented to monitor the process mimic, trend, and alarm. Moreover, the technique can support the operators and engineers to make decision for process control and devices diagnostic.

    In order to provide possibility for system integrators to verify the correctness and effectiveness of functions of a supervisory control and data acquisition (SCADA) system before on-site installation and actual commissioning, this paper presents a process simulation based on software-in-the-loop technique by using VBScript in WinCC for virtual commissioning. Design of integrating an existing control loop in water tank process of pharmaceutical manufacturing plant into a new SCADA is used as a case study. The interested process, which consists of inlet water pump, inlet control valve, level transmitter, and outlet water pump, is controlled by proportional-integral-derivative (PID) algorithm in a programmable logic controller (PLC) to maintain hydrostatic pressure in the water tank. Operations of the simulated process can be controlled in either manual mode or automatic mode. Moreover, the proposed simulation provides an option to imitate device failures that could not be done in real process due to damages for ensuring SCADA fault notification based on failure modes and effects analysis (FMEA). Experimental results of using the proposed process simulation for testing whether the created human machine interface (HMI) screens of the SCADA system integration fulfill functional design specifications are also included.

    This paper describes the technique to integrate HART field devices into SCADA (Supervisory Control and Data Acquisition) system. Wire HART field device is connected to WirelessHART adapter (THUM) and WirelessHART device are assigned act as RTU(Remote Terminal Unit) in SCADA system. In system, THUM and WirelessHART device communicate to WirelessHART gateway that collects their data and send to master station with Modbus/TCP. The paper presents the practices to install and configure the THUM with control valve wire HART device, WirelessHART transmitter, tags assignment, and so on that focus for HART parameters mapping in order to device operation and management. Effectiveness of the proposed system integration is verified by simulation and experimental results. Moreover, the technique can be applied in existing plants or in new project to support end-users to quickly and easily gain the benefits of device diagnostic and decision support for operation and management.

    This paper presents a technique to integrate WirelessHART field devices into SCADA (Supervisory Control and Data Acquisition) system. The proposed technique is based on the use of WirelessHART gateway to function as a Modbus/TCP-based RTU (Remote Terminal Unit) of the SCADA hardware architecture for data communications between the remote wireless site and master station. The master station in the studied SCADA system is composed of a computer with ‘Wonderware HMI (Human Machine Interface)/SCADA’ and ‘Historian Client’ software applications. Methods for configuring the software applications used are described. Based on the ‘Wonderware System Platform’, applications of collected and analyzed data for status and event monitoring are also proposed. Effectiveness of the proposed system integration is verified by experimental results.

    Wireless Technology has promoted in the process automation because it does not require power and communication wiring for field instruments that enables reduced engineering cost. At the same time, end-users consider the developments of process automation by using wireless devices due to the growing of the new plants and replacing analog or wired HART plants. The paper presents a technique to modify wired HART device to be WirelessHART device and to configure it for communication with other WirelessHART devices. A PLC (Programmable Logic Controller) and SCADA system is used to provide centralized device information, historian, and HMI. Installation and configuration techniques of wired HART, THUM adapter or repeater, WirelessHART, HART gateway are described. In addition, engineering and SCADA software are assigned based on OPC to share WirelessHART data with gateway, PLC and SCADA system. The experimental results by using S7-300 Siemens PLC, WW InTouch, and HART devices in level process control are included to confirm the system workability. Moreover, the technique could be applied to collect data for end-user support to quickly and easily gain the benefits of device diagnostic and to decide the plant operation and planning.
