The invention relates to a design method for an embedded generic node with a remote service function. The embedded generic node comprises a CAN (Controller Area Network) functional module and an embedded functional module; the outside embedded generic node comprises four node interfaces, which are respectively a link interface (LIF), a technology independent control interface (TII), a technique dependence debugging interface (TDI) and a local interface link interface (LIF), wherein the LIF and the TDI are used during normal operation period of the node; the TII and the TDI both are control interfaces and used for controlling, monitoring or debugging the node to achieve data acquisition and the functions of process, supervision, control, diagnosis and the like of the strong real-time distributed CAN bus control system. By adopting the design method for the embedded generic node with the remote service function provided by the invention, the site acquisition speed of service data is improved, the application software is simplified, and the integral complexity of the node is reduced; and the designed node occupies small internal memory, and has quick speed, high reliability and good stability.
