Can the device be relocated to another location without using DCS?
Thread Content
The company's existing equipment is planned to be relocated to another location. The old equipment is controlled by panel instrumentation. In order to save money, is it possible not to use the DCS system after the relocation? But it seems* * It is expressly stipulated that DCS control systems must be used in new chemical projects in the future. Where to go?
It is recommended that you get a DCS system. Foreign ones are too expensive, but domestic technology is also very mature. This facilitates centralized management and control of the entire factory and complies with policy requirements.
It can also increase domestic demand. :lol. The price of domestic DCS is good.
If you have a small number of points, you don't need to use it, but if you have a lot of points, it's better to use DCS for easier maintenance.
I think DCS should be used to facilitate production management and save maintenance. So many display instruments are very expensive and inconvenient to maintain.
Are there any such regulations? Does a new chemical plant need a DCS?
It seems that there is, and in some cases SIL certified ESD is required.
I have never heard that DCS is required for new chemical equipment. DCS is relatively popular.
I have never heard that DCS must be installed in new chemical equipment. It is decided by the company itself. It is just the current trend of technological development. DCS in general equipment is not more expensive than conventional instruments in terms of investment. If it is more expensive abroad, you can choose domestically produced ones. Otherwise, PLC is cheaper. Conventional instruments are inconvenient to install, record, maintain, manage, and operate.
* * There is no requirement that new chemical equipment must be equipped with DCS. Mainly based on investment considerations, domestic DCS can be used, including Hollysys and Zhejiang University Sinocon, and the cost will not be too high.
