ABB 3BHB003688R0101 Process Controller
he control function is complete, and the control algorithm is rich, integrating continuous control, sequential control, and batch control. It can achieve advanced control such as cascade, feedforward, decoupling, adaptive, and predictive control, and can easily add special control algorithms as needed. The composition of DCS is very flexible, which can be composed of dedicated management computer stations, operator stations, engineer stations, recording stations, on-site control stations, and data acquisition stations, as well as general servers, industrial control computers, and programmable controllers. The process control level at the bottom level is generally achieved through scattered on-site control stations, data acquisition stations, etc. to collect and control data on site, and transmitted to the production monitoring level computer through a data communication network.
The Yokogawa CentumCS system adopted by our company mainly consists of three parts: control station FCS, operation station HIS, and control network Vlnet.
2.2 Familiarize oneself with the external wiring of the system, understand the control principles of each functional module, and form the concepts of information flow and control flow for each module. Combined with the external wiring diagram, walk through the system hardware several times with each functional module as a unit, until you can clearly understand the actual direction of functional control and information feedback.
2.3 Understand the information of system instruments and control components, combined with the product user manual of each instrument, and be familiar with the information represented by the indicator lights of various components such as controllers, IO cards, power supplies, etc., such as working status and fault prompts. This is even more important now that the self diagnosis function in hardware design is becoming increasingly perfect and popular, and its self diagnosis information covers most of the information we need in daily maintenance work. It is one of the basic starting points for system fault maintenance.
