DCS system management system

In order to ensure the safety and stability of DCS system, it is in a good running state for a long time. This system is specially formulated.

1 engineer station is the configuration maintenance tool of the whole computer distributed control system and the software server of each operator station, which must be strictly managed.

The system engineer is fully responsible for the software, hardware and environment management of the DCS system, and is responsible for the safety of the system.

System members are responsible for the backup and reinstallation of workstation software and database. Control processor CP includes backup and download of board card, processor and database, and all backup data of dcs system is managed by DCS room.

All DCS user passwords are set by the system engineer, and the secondary passwords are properly kept by the deputy director of first-line production. The password used by each team is specified by the system administrator.

5. It is forbidden to display the operating system environment and configuration window on the operating platform operated by each control room.

6 Work related to modifying system configuration and program configuration should be carried out during downtime as far as possible.

7 Maintenance involves the addition, modification, deletion and protection of measuring points, logic and process diagrams, and the release of interlocking signals. The work unit applies, and the scheme and related measures issued by the technical department of Biotechnology Department are signed and approved by the vice president in charge of production, and then reported to dcs room for confirmation. Only after the work is completed can the system maintenance personnel be allowed to enter the engineer's environment to perform the work. After the work is completed, the system maintenance personnel and the thermal control maintenance personnel jointly carry out the functional test, which is signed and accepted by the head of the production department.

8 After each modification and improvement, the relevant window should be closed and the environment changed to the operator environment.

9 For signals released for a long time, they should be processed in the terminal cabinet without software.

During the operation of 10 system, it is forbidden to operate field equipment on the engineer station.

1 1 It is forbidden to bring programs from other systems into this system. If you need to use foreign programs, you need to go through strict inspection and testing, and the testers are required to be very familiar with machine performance and operating system.

12 It is not allowed to connect this system with external systems at will, so as not to cause programs and data files of other systems to enter when using this system.

13 system members regularly check whether the control station, operating station, keyboard, mouse, network card, host and other system-related equipment are in a safe state and whether the environment may affect the stable operation of the system.
