There are many kinds of DCS cards. Take JX-300XP system as an example to clarify which aspects are composed of:
JX-300XP cards are divided into:
The main control card, such as xp243x, is mainly responsible for the operation of the control station system;
Data transfer card issuing, such as xp233. Connecting the bridge between IO card and master card;
Various IO cards, such as xp363, xp362, xp316, xp313, xp322, etc. Mainly responsible for inputting and outputting all kinds of digital and analog quantities on site;
Other functional cards, such as xp248 multi serial port multi protocol communication card, are used to communicate with other intelligent devices (PLC, frequency converter, etc.)
Xp221 and xp000 are mainly used to occupy space (otherwise, a slot of the cage will be empty if there is no card).
As a computer control system in the field of production process automation, the traditional DCS is only a narrow concept. If we think that DCs is only the automation system of the production process, it will lead to the conclusion of fault. Because the meaning of the current computer control system has been greatly expanded, it not only includes various contents contained in DCS in the past, but also deepens to each measuring equipment and actuator on the site, and develops upward to all aspects of production management and enterprise management. DCS in the traditional sense now only refers to the automation of production process control, while the concept of industrial automation system should be positioned at the level of enterprise comprehensive solution, that is, total solution. As long as problems are raised and solved from this point of view, computer automation can really play its due effect.
