Strengthen training and standardize operating procedures
When maintaining the DS system, it is necessary to standardize the operating procedures, as there are significant safety hazards in some work. Relevant personnel should receive training on relevant work experience to prevent DCS communication failures caused by human factors. For example, when uninstalling application software in the system, changing control parameters, and modifying human-machine interfaces, it is necessary to strictly follow relevant regulations to effectively reduce the likelihood of DCS system failures.
Node bus failure
The material of node bus is usually coaxial cable, so as long as one cable is disconnected, the communication of all devices on the bus will be paralyzed, causing serious phenomena such as data loss, equipment shutdown, and operation interruption, which may ultimately cause huge losses directly or indirectly. Frequent plugging and unplugging of coaxial cables can lead to poor contact and signal interruption. Excessive contact resistance can also have an impact on communication lines, and a large data load during transmission can lead to a decrease in data accuracy.
To solve the above problems, dual redundancy can be used, but the cable connection should be located behind the module to ensure that the coaxial cable is not adversely affected by mechanical operation. Only perform unplugging and unplugging when maintaining the node bus, and multiple unplugging and unplugging are prohibited unless there are other special circumstances. Ensure that the contact resistance of the circuit is at a normal level and regularly check the resistance of the circuit
