11.3 HMI

• HMI – Human Machine Interface• MMI – Man Machine Interface

(older name for HMI)• SCADA – Supervisory Control and Data

Acquisition

HW and SW means for operator and supervisor control

(various types of operator panels and PCs, software packages for operator panels programming and for visualization)

HMI - Operator panels

• Two main parts:display - only textual

- graphical -monochromatic - colour

buttons - with predefined meaning(minimal configuration:up, down, OK, ESC)

- free for user configuration - numerical

Operator panels - 2

Textual operator panel TD2OO (Siemens)

Operator panels - 3

Textual operator panel TD200 • Suitable for simple HMI applications in

connection with PLC SIMATIC S7-200• LCD displey with two rows for 20 characters• Four function keys (buttons) F1 to F4• Four system keys (buttons)

- (up, down for listing through messages and parameters setting, OK – confirmation, ESC –return)

Operator panels - 4

• For connection to the PLC SIMATIC S7-200 or to the PC only one interface PPI (peer to peer interface) - RS 485.

• Speed: 9,6/19.2/187,5 kbit/s.

11.4 Visualization of technological processes

Representation of technological process behavior on display (operator panel or PC)

• Technological information

- (technological variables values – e.g. pressure, temperature, level, position, number of pieces, type of pieces, delays etc.)

• Information about control of the process

- (state of sensors, state of actuators, controller parameters, step in sequential control etc.)

Visualization of technological processes - 2

• Operator interface for - Change of individual parameters or the whole

set of parameters (data structure – recipe)- Manual control of the process (e.g. possibility

to manipulate with motors) - Error handling- Alarm procesing - Data acquisition (e.g. for longterm statistic

evaluation of quality or performance)

Visualization of technological processes - 3

SW for visualization:
