About:
The main target of this document is to define the MIC 4.0 BUS as a communication interface between construction machine (carrier) and connected attachments. In the following chapters, all relevant aspects of the MIC 4.0 BUS are explained which in combination with the MIC 4.0 BUS database and the message layout should enable engineers to implement the MIC 4.0 BUS on construction machines and attachments.
The documents cover machine and attachment architecture requirements as well as definitions of the CAN line and termination. Addressing and other basic communication rules based on J1939 are explained. To enable safe operation of attachments, the MIC 4.0 BUS safety concept covers the safety requirements that need to be followed to be compliant to the standard.
Based on the MIC 4.0 BUS database, the different messages that make up the communication on the bus and the corresponding machine and attachment functions are explained. This is amended by necessary definitions, including an attachment classification and the definition of attachment geometry parameters.
