Even identical processes can have vastly different HMI screens, depending on who implemented them and customer desires. you have to move value 1 to 30 in that register if you using same delta hmi. We see flickering flames to represent a flare, moving rail cars in loading bays, some have gone as far as to take digital photos of the actual process floor and overlay data on the HMI screens!Īdd this mindset to the thousands of systems integrators, and we end up with an industry with no standard displays.
