Comparison of Hilscher and Zhejiang University Zhongkong’s DCS
Thread Content
Our company’s DCS system has around 2,000 points; we are in the chemical industry. We are currently in the bidding phase, and I would like to know which is better – Allen-Bradley’s MACCS 6 or Zhejiang University’s 700 series. The price of Zhejiang University’s system is 70,000 yuan higher.
I’ve used the Allen-Bradley MACSV451, and it’s not very user-friendly. I haven’t used the latest models yet. I’ve also used the 700 control system, which is relatively better, but in terms of underlying logic there isn’t really much difference; all domestic products are similar
Zhongkong seems to be good at the chemical industry – is the price difference significant?……
Ever since STMicroelectronics started charging for additional IO points, it became useless for us; that was over a decade ago, and now everything is handled by central control systems.
Will it reach 700 at 2000 points?
If Zhejiang Zhongkong provides the instruments, absolutely avoid it – the instruments they supply are of poor quality and their service is inadequate. It was only used last year.
The ECS700 has a low failure rate; it is a stable product with a low failure rate, and its price is not particularly high. It takes slightly longer to learn how to use compared to Hilscher products. HollySys systems are simple to operate and inexpensive, but they have many minor issues; no major problems. It depends on your choice; all the functions can definitely be implemented.
