2 . T e c h n i c a l System Description
Operation is accomplished via a touch screen (TFT monitor). Two
microprocessor systems control and monitor the machine.
The hardware concept consists of the following systems:
• Top Level System
• Low Level System
The top level system consists of the following components:
• Communication module
• Top level controller TLC (motherboard)
• Compact flash card CFC
• Options
The communication between the user and the machine is performed via the
top level.
Example data exchange to communication module:
• Entry via input mask of the touch screen or keyboard
• Output via the output mask of the TFT monitor
Example data exchange to low level:
• Transmitting and receiving data from/to low level controller and supervisor
on the digital board DB (LLD)
The low level system consists of the following components:
• Digital board DB (LLD)
• Analog board AB (LLA)
• Power board motors PBM
• Power board valves PBV
The low level controls and monitors all functions.
Data exchange to top level controller (motherboard):
• Transmitting and receiving data from/to low level supervisor
• Transmitting and receiving data from/to low level controller
Data exchange between low level controller to supervisor:
• Transmitting and receiving messages, data and commands
All sensor data are sent separately, via two serial bus systems, to the supervisor
and controller via the analog board to the digital board. The actuators, motors
and valves are driven via the power board valves PBV and power board motors
PBM.
