Timely carry out data backup work
Regular and timely backup of DCS configuration software, PID parameters, and various application software data is necessary. Backup can be done using portable hard drives, USB drives, etc., but it is best to use DCS dedicated memory. When the DCS system needs to optimize and modify test points and logic during operation, it is necessary to backup the configuration in advance and make detailed system records, such as PID parameters of each control circuit, positive and negative effects of regulators, etc
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
