As defined in ISO 15765-4, emissions protocols (including OBD-II, EOBD, UDS, etc.) use the ISO-TP transport layer (ISO 15765-2). All CAN frames sent using ISO-TP use a data length of 8 bytes (and DLC of 8). It is recommended to pad the unused data bytes with 0xCC. The PID query and response occurs on the vehicle's CAN bus.
A controller area network (CAN) is a vehicle bus standard designed to enable efficient communication primarily between electronic control units (ECUs). Originally developed to reduce the complexity and cost of electrical wiring in automobiles through multiplexing, the CAN bus protocol has since been adopted in various other contexts.
Agricultural implement ISOBUS plug. ISO 11783, known as Tractors and machinery for agriculture and forestry—Serial control and communications data network (commonly referred to as "ISOBUS") is a communication protocol for the agriculture industry based on, and harmonized with, the SAE J1939 protocol (which is based on the CAN bus).
This was true as of 2000. Since then, CAN has been included, the chipset for J1939 has been clocked faster [clarification needed], and 16-bit addresses (PGN) have replaced 8-bit addresses. J1939, ISO 11783 and NMEA 2000 all share the same high level protocol. SAE J1939 can be considered the replacement for the older SAE J1708 and SAE J1587 ...
ISO 15765-2, [1] or ISO-TP (Transport Layer), is an international standard for sending data packets over a CAN-Bus. The protocol allows for the transport of messages that exceed the eight byte maximum payload of CAN frames. ISO-TP segments longer messages into multiple frames, adding metadata (CAN-TP Header) that allows the interpretation of ...
A Piping and Instrumentation Diagram (P&ID) is a detailed diagram in the process industry which shows process equipment together with the instrumentation and control devices.
The PSI data as defined by ISO/IEC 13818-1 (MPEG-2 Part 1: Systems) includes four tables: PAT (Program Association Table) CAT (Conditional Access Table) PMT (Program Mapping Table) NIT (Network Information Table) The MPEG-2 specification does not specify the format of the CAT and NIT. PSI is carried in the form of a table structure.
Challan or Chalan is a common Hindi word (चालान, cālān) that has become an Indian English technical word used officially in many professional, especially financial transactions. It usually means an official form or receipt of acknowledgement or other kind of proof document, piece of paperwork, police citation, etc.
