Create Extended CAN IDs.vi
Purpose
Creates diagnostic CAN IDs according to ISO 15765-2.
Format
Input
addressing mode specifies whether the ECU is physically or functionally
addressed.
transport protocol specifies whether normal or mixed mode addressing is
used.
source address is the logical address of the host (diagnostic tester).
target address is the ECU logical address.
Output
transmit ID is the generated CAN identifier for sending diagnostic request
messages from the host to the ECU.
receive ID is the generated CAN identifier for sending diagnostic response
messages from the ECU to the host.
Description
ISO 15765-2 specifies a method (extended/29 bit) of creating 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 VI implements the
construction of these CAN identifiers. You can use them directly in Open Diagnostic.vi.
