Description

ISO 15765-2 specifies a method for creating (extended/29 bit) CAN identifiers for diagnostic
applications given the addressing mode (physical/functional), the transport protocol
(normal/mixed), and the 8-bit source and target addresses. This function implements the
construction of these CAN identifiers. You can use them directly in the

ndOpenDiagnostic

function.
