A human-machine interface (HMI) device is the primary tool by which the operator can read and control the main parameters of the system or installation. The parameters and current status presented on the HMI display are grouped on individual screens, corresponding to functions controlled by the PLC unit.
As standard, the HMI is mounted in an electronic rack, but can also be mounted as an additional, large touchscreen on a rotary arm. For convenience, the HMI device can be integrated with the system frame, e.g. right next to the process chamber.
The HMI device can read and control e.g.:
▪ vacuum level,
▪ gate valves,
▪ switch box,
▪ opening/closing the shutters,
▪ manipulator motion/positioning,
▪ sample holders transferring,
▪ sample holders heating & cooling,
▪ gas dosing,
▪ safety interlocks.
