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.

Operator panels - 5 Touch panel TP070 (Siemens)

Operator panels - 6 Touch panel TP070 Suitable for simple or more complicated HMI applications in connection with PLC SIMATIC S7-200 The smallest operator panel build on Windows CE architecture It is possible to display user grafics, dynamic bar graphs, dynamic application variables, user buttons in four intensities of gray graphics resolution 320x240 pixels One interface RS 485, maximal speed 19,2 kbit/s

Operator panels - 7 Touch panel TP070 based on 32-bits processor RISC/66 MHz and user memory flash 128 Kbyte. life cycle 6 years continuously For programming: TP Designer in collaboration with MicroWIN V3.1 and higher. It is possible to connect this panel to another devices with MPI cable or Profibus DP cable.

Operator panels - 8 Multipanel MP370 (Siemens)

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: Siemens: WinCC Schneider Electric – PL7 Pro (only for simple applications) Festo: ViP Teco: Reliance Large SW packages for visualization (drivers for most famous PLCs):
