Explain how operators interact with controllers.
What will be an ideal response?
Operators interact with controllers through a control or computer called a human machine interface (HMI). Early HMIs were usually custom-made boxes with gauges and switches. Today, an HMI is most likely a PC running a custom, touchscreen interface. It's important to appreciate that HMIs are not general purpose. You wouldn't run Microsoft Office on an HMI, even if the PC on which it is built is capable of such things. It's very common for an HMI to show a single interface that never changes.
