Dear netizens, can the PLC control system of a centrifuge be integrated into a DCS system to achieve full-process automation? If it’s possible, how is it achieved? If not, what’s the reason? We welcome everyone’s extensive suggestions for joint learning; thank you!
Typical centrifuges come equipped with a PLC, which enables automatic control within the unit; the DCS is needed only to communicate with it and display data. Wired connections can be added, such as for an emergency stop function on the DCS. If you want to achieve automation, it depends on what functions you wish to implement, such as automatic frequency adjustment Also, what is your centrifuge used for? Three-phase deceleration centrifuge? Or what?
Cancel the PLC; a DCS can also be used
Sure, I heard that Wanhua is working on this – a unpacking program, along with DCS configuration is all that’s needed. But the supplier’s cooperation is needed; some manufacturers are unwilling to do this as it takes too much time and requires them to work together with the client for debugging
Whether considering DCS performance or the lead time for supplying PLC cards, replacing PLCs with DCS is a fully viable option, with advantages outweighing the disadvantages. The manufacturer needs to provide a control scheme.
It’s the ordinary type of centrifuge used for discharging materials, the kind used for separating solids from liquids
Yes, you’re absolutely right; the centrifuge manufacturers are unwilling to cooperate
Through everyone’s explanations, I understood it; thank you very much for your suggestions
It’s feasible, but it’s too troublesome to coordinate everything
During the bidding process, it was specified that no PLCs would be used; the manufacturer could bring its own instruments, with the control system to be implemented via DCS. The advantage is that it is easy to maintain, and the cost of adding a few points to a DCS is lower than that of a PLC cabinet. If the manufacturer’s brand is too strong, it’s necessary to build good relationships with the technical staff in order to obtain access to the PLC configuration files and passwords.
