Description

Symphony Plus controllers seamlessly integrates HART field devices through S+ I/O HAI805 and HAO805 HART modules. This allows access to a wide range of intelligent field devices including transmitters and actuators from ABB and other vendors. In general, HART devices superimpose digital signals on top of the standard 4-20 mA signal it communicates, providing the possibility to deliver much more device or process data to the control system than conventional 4-20 mA field devices.

Whereas most HART I/O modules utilize a common HART modem or multiplexer for the entire module, thereby limiting use of the data to the HMI level only, HAI805 and HAO805 modules have dedicated HART modems for each I/O channel. This allows for better signal isolation and faster processing, and it makes the secondary, tertiary and quaternary digital variables available for use in real-time control applications.

The problems with on-site signals mainly include the following aspects: 1) damage to measuring components 2) transmitter failure 3) wiring problems (including loose and detached signal wires during transmission, grounding, and interference beyond the acceptable range of DCS during transmission, etc.) In short, any link between signal measurement and DCS wiring terminals is incorrect, The results are all manifested as incorrect data display. 2. DCS hardware failures are often manifested in the following aspects: 1) the module and base are not tightly connected; 2) the dial switch is incorrect in the direction of the communication line wiring and the terminal matcher is not connected; 3) the hardware jumper is not consistent with the actual signal requirements; 4) the power output in the cabinet is incorrect; 5) the hardware itself is damaged. The results of these problems are: after power on, the hardware board level malfunctions (the indicator light display status is abnormal); Equipment not working; The system is working but the displayed corresponding measurement point values are incorrect. The output of the system cannot drive on-site devices, etc.

3 Common faults in power supply and grounding systems
1) There is a problem with the power connection and there is no connection (one of the few items on fire and ground is not connected); Incorrect connection (reverse connection between live wire and zero wire, reverse connection between ground wire and zero wire, multiple short connections between ground wire and zero wire)

2) Power quality issue Equipment connection quality (loose connectors); Technical indicators (such as voltage and frequency) exceed the specified requirements.

3) Quality issues with power lines. The impedance of the power lines increases and the insulation layer is not good.

4) Ground electrode issues. The resistance of the ground electrode increases and the ground electrode is disconnected from the ground grid.

5) Environmental issues. The wiring of power lines, especially the ground wire, is unreasonable and is too close to wires and equipment that generate strong magnetic field interference. When encountering faults, it is necessary to analyze and eliminate them one by one to ultimately find a solution to the problem, In order to grasp the main contradictions and achieve the goal of quickly troubleshooting, in order to minimize the occurrence of DCS system faults and maintain the normal and efficient operation of production, we need to do the following work well: 1) Regular inspection of DCS system and hardware equipment 2) Regular backup of DCS system database and application programs 3) Regular calibration of on-site instrument equipment to ensure the accuracy of data collection 4) Regular inspection of grounding system
