At the risk of displaying my ignorance and therefore looking daft – here goes.
Our plant uses SCADA on a profibus network and we have a data historian networked around the site. In recent times we have added instruments onto this network which connect by WiFi rather than hardwired.
As far as I understand, IOT and Industry 4.0 is an extension of the above trend to WiFi connection as web enabled instruments and sensors drop in price.
Q1 Is my very basic understanding correct ?
Q2 Is there a different central organising hub for IOT/ Industry 4.0 than the SCADA or data historian we use ? If so what are its characteristics ?
