GF54.00-P-0004-04A Data Bus System, Advantages
GF54.00-P-0004-04A Data Bus System, Advantages
With the former wiring of the individual electrical and electronic components (standard wiring) each control unit is directly connected to all sensors and
actuators, from which it obtains measured values or which it actuates.
In some cases, this can result in long or redundant cable runs. The data bus system affords the following advantages relative to conventional wiring:

GF54.00-P-0004A Data Bus System Function
A data bus connects the individual control units and enables them to exchange data.
The signal from a sensor is passed on to the nearest control unit, processed by it and placed on the CAN data bus.
Each control unit that is connected to the CAN data bus can read this signal and use it to calculate an input to control an actuator.
