Discussion on the integration of workshop chiller control into DCS
Thread Content
I would appreciate some advice: Is it necessary to connect the controller of the chiller unit in the workshop to the DCS system? And if so, is it required to control the chiller unit from the DCS side?
I’m not qualified to give advice on this. In my opinion, it would be useful to establish communication between the unit controller and the DCS system, so that the operating status of the unit can be displayed on the DCS for easier monitoring. As for whether to enable start/stop functions, it depends on whether there is a need for them
Communication with DCS can be achieved using 485; a new DCS interface needs to be created
The communication is pretty good; otherwise, it would be difficult to control both of them
If it seems okay, I’d give it an excellent rating:lol
I have a gentle question: do chillers use lithium bromide?
If the controller of the unit communicates with the DCS, it is possible to detect important signals at the site. If DCS directly controls critical parameters of the unit, hardwired connections are necessary, as communication is generally considered unsafe.
