(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

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)
