Portable Design;Apr2004, Vol. 10 Issue 4, p28
A revision to the Local Interconnect Network protocol is the 2.0, which replaces 1.3, a major revision upgrade. This revision continues to standardize and ensure compatibility between communicating modules as well as simplify the use of off-the-shelf slave nodes. The list of improvements includes an enhanced checksum, reconfiguration and diagnostics, automatic baud-rate detection, and Response_Error status monitoring. Off-the-shelf modules have driven the need for standardization of configuration and diagnostics and specified node-capability files. Three methods for collecting diagnostic information are now defined. These are signal-based diagnostics, user-defined diagnostics, and diagnostic transport layer.
