Hi,
This is one of the questions which keep on popping up in many circles of automation. Many have a view that, nowadays, the line between PLC & DCS is almost blurred. Whether is I/O count or networking features, almost PLC has all the features.
However, what is left after that almost??? PLC has fast response time compared to DCS. DCS can support much more I/O than PLC but PLC's of rockwell have comparable IO to any DCS.
Many Views but at last i'm not sure what exactly the difference is!!!
If no difference at all then why two names??
And why a new breed of PAC's (Process automation controllers) emerged??
How its different??
Thanks & Regards
