Description
Description:
IS210AEBIH3BEC is a terminal board. This component provides an electrical interface between the turbine control terminal board and one or two Ethernet networks. The output of this battery pack is carried out through a DC-62-pin connector connected to the relevant terminal board.
Market situation and development direction of DCS and PLC
In the field of thermal automation, the control system of the main factory building basically uses DCS without exception. PLC is only used in auxiliary workshops. The main reason for this is that early DCS systems were very expensive, and people believed that the operation of auxiliary workshops could be interrupted, with low reliability requirements, and fewer requirements for analog control. From the perspective of reducing costs, PLC was often chosen to build control systems. The control systems of boilers, steam turbines, and generators require long-term stable and reliable operation, and the signals contain a considerable proportion of analog quantities. From the perspective of system performance, people have to choose expensive DCS. Additionally, by analyzing the market competition between the main workshop DCS and auxiliary workshop control systems, we will discover an interesting phenomenon. The competition for DCS in the main factory is often fierce among suppliers or agents of different brands, and the prices of DCS are constantly decreasing. The competition for auxiliary workshop control systems often takes place among various engineering companies of the same brand PLC, with lower barriers and more intense competition. However, the price reduction of PLC is not as significant as that of DCS. The main reason is that DCS manufacturers directly participate in competition and continuously reduce equipment manufacturing costs and engineering implementation costs under enormous market pressure. However, PLC manufacturers do not directly participate in competition, and each engineering company can only lower their limited engineering costs due to limited space. From the current situation, the price difference between DCS and high-end PLC is no longer significant, and auxiliary workshops still use PLC more, which is due to the inertia of the market.
With the continuous expansion of the installed capacity of domestic power plants and the promotion of power system reform, the requirements for auxiliary workshop control are also constantly increasing. In this environment, it has become a trend for DCS systems to enter auxiliary workshop control. Due to its comprehensive technical and economic advantages, NETWORK 6000+DCS has played and will continue to play an increasingly important role in assisting workshop control. PLC, which is widely used in auxiliary workshops, will not withdraw from the historical stage of thermal automation. The unprecedented competitive pressure will encourage PLC manufacturers to approach DCS standards in technology and make greater efforts in price. The result of market competition will enable users to gain greater benefits.
Conclusion
DCS and PLC, as products of the combination of computer technology and control technology, have made their respective contributions to the improvement of thermal automation level in thermal power plants. Due to their significant similarity in application, their respective technological or price advantages at different times will directly affect their market position. And the market’s response will also be reflected quickly or slowly in their respective technological development and price adjustments. From the overall trend, the integration and promotion of DCS and PLC in technology will be the mainstream of competition, and in terms of cost-effectiveness, you come and go, constantly rising, will also be the main theme of development.
