The HMI device in the operating process
The HMI device is part of the operating process. The operating process is marked by three-
way communication between the HMI device, server and PLC. The following figure shows an
exemplary system design.
The HMI device is used for monitoring or controlling the operating process. The PLC in turn
supplies the server with the results of the operating process, which are displayed on the HMI
device.
