5 About this product
5.1 Product description DI4
With the BODAS display DI4, Bosch Rexroth is offering a freely programmable
high-resolution color display with a powerful 32 bit processor and a display
diagonal of 7".
Depending on the programming, the display enables, for example, process variables,
static and dynamic graphic elements and the operation of machine functions to be
displayed on one central unit.
The robust display DI4 has been developed specifically for use in mobile working
machines and satisfies corresponding protection requirements regarding
ambient temperatures, impermeability, shock and vibration and electromagnetic
compatibility (EMC). It is intended for installation or assembly in the driver's cab
and offers excellent readability, even in sunlight and harsh climatic conditions.
The brightness of the lighting is adjustable. An ambient light sensor automatically
adjusts the backlighting. The color and brightness of the keys, the push-turn control
and the icons can be changed and can be adapted to the machine manufacturer's
individual design.
12 freely programmable function buttons are available for user input and menu
navigation (softkeys) . The display features an ergonomically arranged central
push-turn control for fast navigation on and between the different screens or menus
for easy adjustment of values. The display also has two other function buttons
(hardkeys), which can have fixed functionality occupancy (such as cancel, main menu)
assigned to them comprehensively across projects. In the PRO variant, a capacitive
touch screen is also available. The front the displays has an anti-fog layer to avoid
fogging in case of rapid temperature fluctuations.
The application-specific representation of screen pages, context menus,
graphic elements and video signals is provided by the CODESYS programming
environment. The integrated LEDs and the loudspeakers can be used as enhanced
status indicators.
The display can read and process analog or digital input signals directly and can also
control 2 digital live outputs.
The BODAS display is intended for use in 12 V or 24 V electrical battery systems.
The internal real-time clock is buffered against supply voltage interruption
(approx. 500 h). Communication with the BODAS controllers of the current series
and other electronic assembly groups in the machine takes place via CAN bus.
The PRO variant of the display DI4 is also equipped with an Ethernet interface,
which is routed via a separate external connector.
The displays DI4 can be flashed via CAN bus using a BODAS-service tool or
preferably at a higher speed via USB or Ethernet (PRO version).
The DI4 displays can also be used for gateway access to the BODAS controllers to be
used as diagnostics and service interfaces for configuration and flashing of software
on the BODAS-RC control units or the display DI4 itself. The parameters that are
stored in the BODAS controllers can be read, changed and written back to the
BODAS via the DI4 CAN interface. The representation of the active and stored errors
of a BODAS controller and the resetting of the error are possible via the DI4 using
the BODAS-service function.
