Unified Diagnostic Services. Unified Diagnostic Services (UDS) is a diagnostic communication protocol used in electronic control units (ECUs) within automotive electronics, which is specified in the ISO 14229-1. [ 1 ] It is derived from ISO 14230-3 (KWP2000) and the now obsolete ISO 15765 -3 (Diagnostic Communication over Controller Area ...
ISO 15765-2. 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 ...
Keyword Protocol 2000. Keyword Protocol 2000, abbreviated KWP2000, is a communications protocol used for on-board vehicle diagnostics systems (OBD). This protocol covers the application layer in the OSI model of computer networking. The protocol is standardized by International Organization for Standardization as ISO 14230.
The HART Communication Protocol (Highway Addressable Remote Transducer) is a hybrid analog+digital industrial automation open protocol. Its most notable advantage is that it can communicate over legacy 4–20 mA analog instrumentation current loops, sharing the pair of wires used by the analog-only host systems. HART is widely used in process ...
SAE J1939. Society of Automotive Engineers standard SAE J1939 is the vehicle bus recommended practice used for communication and diagnostics among vehicle components. Originating in the car and heavy-duty truck industry in the United States, it is now widely used in other parts of the world. SAE J1939 is used in the commercial vehicle area for ...
Modbus Serial Line protocol is a master-slave protocol which supports one master and multiple slaves in the serial bus. [ 20 ] With Modbus protocol on the application layer, client/server model is used for the devices on the communication channel. With Modbus over Serial Line, client's role is implemented by master, and the server's role is ...

IEC 61850 is an international standard defining communication protocols for intelligent electronic devices at electrical substations. It is a part of the International Electrotechnical Commission's (IEC) Technical Committee 57 reference architecture for electric power systems. [1] The abstract data models defined in IEC 61850 can be mapped to a ...
