First Claim
1. A building machine, comprising:
- a chassis;
a running gear supporting the chassis;
a working unit supported from the chassis and comprising one or more implements, each implement controlled by one or more actuators;
one or more sensors configured to provide output signals representative of an associated operation;
a Programmable Logic Controller (PLC) storing one or more programs and operational parameters and thereby configured toreceive and process the output signals from the one or more sensors, andtransmit control signals to the one or more actuators to control the operation of the working unit;
a display unit configured to display one or more operational variables of the machine or one or more operational states of the machine in the form of characters or images;
a central data processing unit including a main processor and a graphic unit, the central data processing unit being configured to control the display by the display unit of the one or more operational variables of the machine or the one or more operational states of the machine in the form of characters or images;
a first data bus connecting the central data processing unit with the PLC, the first data bus being configured to operate according to a first data transmission method; and
a second data bus connecting the central data processing unit with the display unit, the second data bus being configured to operate according to a second data transmission method different from the first data transmission method.

Abstract
The invention relates to a building machine, in particular a road-building machine, having running gear and a chassis which is fitted with a working unit which has one or more implements. The building machine has a stored-program control device for controlling the implements of the working unit and a device for displaying operational variables or operational states in the form of characters or images. In addition to the stored-program control device, the building machine has a centralized data processing device which is embodied in such a way that operational variables or operational states can be displayed as characters or images with the device for displaying operational variables or operational states. The exchange of data between the stored-program control device and the centralized data processing device is carried out via a first data bus, while the exchange of data between the data processing device and the device for displaying operational variables or operational states is carried out via a second data bus.
