A CAN network can be configured to work with two different message (or "frame") formats: the standard or base frame format (described in CAN 2.0 A and CAN 2.0 B), and the extended frame format (described only by CAN 2.0 B). The only difference between the two formats is that the "CAN base frame" supports a length of 11 bits for the identifier, and the "CAN extended frame" s… WebNov 28, 2024 · If the ID is being read with the ncReadNet.vi or the ncReadNetMult.vi, the extended arbitration ID must be XOR'd with the same hexadecimal number 0x20000000.

WebMar 3, 2024 · The distinction between CAN base frame format and CAN extended frame format is accomplished by using the IDE bit inside the Control Field (See image below). A low (dominant) IDE bit indicates an 11-bit message identifier; a high (recessive) IDE bit indicates a 29-bit id.
WebSep 22, 2024 · Message addressing. Communication in the CAN network is based on content-related addressing. It is not the CAN nodes that have identifiers, but rather the data and remote frames are identified (identifier — ID). So, all CAN messages can be received by every CAN node (broadcasting).

This means that CAN simply enables the transmission of frames with an 11 bit CAN ID, a remote transmission (RTR) bit and 64 data bits (fields relevant to higher-layer protocols). In other words, CAN bus plays the same role in CANopen as it does in e.g. the J1939 protocol. kenneth kiesler university of michiganWebWhat is a CAN frame? Communication over the CAN bus is done via CAN frames. Below is a standard CAN frame with 11 bits identifier (CAN 2.0A), which is the type used in most cars. The extended 29-bit identifier frame (CAN 2.0B) is identical except the longer ID. It is e.g. used in the J1939 protocol for heavy-duty vehicles. kenneth kiler carroll county
