The user interface in a manufacturing or process control system. It provides a graphics-based visualization of an industrial control and monitoring system. Previously called an “MMI” (man-machine interface), an HMI typically resides on a computer that communicates with a specialized computer in the plant, such as a programmable automation controller (PAC), programmable logic controller (PLC) […]

Common ICS Components – Engineering Workstations
A specialized type of HMI, typically interface with the servers to modify the database or controllers to ensure the critical process runs properly. As we gain an understanding of the similarities between IT and ICS architectures, we will have greater success mapping traditional cybersecurity issues into the ICS domain.
