Each Ether CAT command consists of an Ether CAT header, the data area and a subsequent counter area (working counter).

This working counter is incremented by all Ether CAT devices that were addressed by the Ether CAT command and have exchanged associated data. While the telegram (delayed by only a few bits) is already passed on, the slave recognizes relevant commands and executes them accordingly.

Upon reception and interpretation of the ID, one slave begins the message response, which consists of one to eight bytes of data and an 8-bit checksum. Version 1.3 finalized the byte-layer communication. Versions 2.0 and 2.1 added more messaging specifications and services but are compatible at the byte level with LIN 1.3.

The master controls the sequencing of message frames, which is fixed in a schedule. This feature is not natively supported by the API; however, you can implement the functionality. Comparison of LIN Versions 1.3, 2.0, and 2.1 Back to Top The LIN bus is a polled bus with a single master device and one or more slave devices.

It has changed quite a bit since, and the original tools from extreme-linux and beowulf sites will not work with this version of the driver.

For new versions of the driver, updated userspace tools, and who to ask for help, please follow the links at the end of this file.

Examples of areas where LIN is and can be used in a car: window lift, mirrors, wiper and rain sensors.

The LIN-bus transceiver is a modified version of the transceiver used by the ISO 9141 standard.

It can be especially useful to understand the difference between PDO data and SDO data and the synchronisation mechanism of DCclock.The Local Interconnect Network (LIN) bus was developed to create a standard for low-cost, low-end multiplexed communication in automotive networks.Though the Controller Area Network (CAN) bus addresses the need for high-bandwidth, advanced error-handling networks, the hardware and software costs of CAN implementation have become prohibitive for lower performance devices such as power window and seat controllers.The bus is bidirectional and connected to the node transceiver, and also via a termination resistor and a diode to Vbat of the node (Figure 1). (from the LIN 2.0 spec) On the bus a logical low level (0) is dominant and a logical high level (1) is recessive.Voltage supply (Vsup) for an ECU should be between 7 V and 18 V.In the middle of 1999 the first LIN protocol (1.0) was released by this syndicate. In November 2002 LIN 1.3 was released with changes mainly made in the physical layer. With LIN 2.0 came some major changes and also some new features like diagnostics.
