The so-called "remote frame" is a misunderstanding on the traditional translation. Remote Frame in fact it is the meaning of "remote frame" remote frame originator initiates a specific ID, and transmits only the ID portion, the ID matching its obligation data terminal equipment takes over control of the bus section and in the rear half section sending its own data.
Figuratively, the machine needs to control the timing of acquiring the data a node (e.g., the real-time speed tachometer, fuel gauge, real-time oil and the like) may be transmitted to the remote frame bus; determining a respective node receiving the frame ID matches with the own and in the case of remote frame, you can send their data onto the bus in real time; this machine in the control on access to real time data associated nodes.
The greatest advantage is the remote frame only time one will be able to complete a two-way interaction.
