Software failures are usually caused by software programming errors, which usually occur after the DCS system is put into operation or after software upgrades. Most software programming is complex, and there are also situations where configuration personnel cross work, resulting in software errors. The software used in the DCS system mainly includes installing workstation tools and monitoring software.

▶ Fault analysis:
Software failures are mainly reflected in the following aspects:
① The main CPU configuration and slave CPU configuration information are inconsistent, and the CPU cannot initialize properly.
② The database configuration and channel connection signals cannot achieve effective matching.
③ System chaos caused by network communication congestion.
④ Printer printing failure.
⑤ After replacing the component once, there was an error in setting the variable parameters.
⑤ The device is not working properly, and the system output cannot drive the device to work properly.

▶ Fault handling:
Under normal working conditions, there are fewer software failures, which mainly occur after modifying the unit configuration and during the unit debugging process. The application of mature software is the foundation for ensuring the normal operation of the DCS system.
Before carrying out unit maintenance and renovation or debugging, it is necessary to implement a comprehensive renovation plan and conduct effective technical disclosure according to the content of the plan to ensure the effective implementation of relevant systems and avoid software failures caused by human error. In addition, reasonable backup methods need to be adopted to avoid data loss caused by software failures.

Example of DCS system fault handling:
Problem: A certain enterprise adopts the CENTUM CS1000 distributed control system, which is a new generation DCS system developed based on the architecture of Windows 2000 Professional. The system utilizes a reliable bus real-time control network VLNET to achieve process control. After the system was upgraded, there were occasional instances where the temperature control circuit of the electric baking furnace switched from automatic to manual mode, and an open circuit alarm occurred.
Analysis: It was found that the system’s construction cables were damaged and the shielding layer was perforated, as each heating section of the roasting furnace had three phases and thirteen heating sections. During operation, a large magnetic field was formed, and the control signal line induced interference from the magnetic field, which was input to the DCS system and caused a malfunction. Afterwards, all cables will be replaced to standardize construction procedures and achieve the goal of eliminating faults.
