What card is dcs composed of and what is its role? The manufacturer of Zhejiang University's central control DCS card reminds you that there are many kinds of DCS cards. Take the JX-300XP system as an example.
Its cards are divided into: main control card, such as XP243X. It is mainly responsible for the operation of the control station system;
Data transfer card, such as xp233. Connect the bridge between the IO card and the main control card;
Various IO cards, such as XP363, xp362, xp316, xp313, xp322, etc. Mainly responsible for input and output of various digital and analog quantities on site;
Other functional cards, such as XP248 multi serial port multi protocol communication card, are responsible for communication with other intelligent devices (plc, frequency converter, etc.)
XP221 and XP000 are mainly used to occupy the 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 you think that DCS is just an automatic system in the production process, it will lead to a wrong conclusion, because the meaning of the current computer control system has been greatly expanded. It not only includes all kinds of contents contained in DCS in the past, but also goes down to each measuring equipment and executive mechanism on the site, and develops to all aspects of production management and enterprise operation.
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 solutions, that is, total solution. Only from this point of view can computer automation play its due role.
