No existing implementation performs to this level. An installation has to be configured at the network topology level and at individual nodes or devices. CAN bus, otherwise two nodes would continue transmission beyond the end of the arbitration field (ID) causing an error. Distributed Access Architecture (DAA) covers Remote PHY and Remote MACPHY and has as the goal, moving functions closer to end customers, allowing for easier capacity expansions as centralized facilities for equipment are downsized or potentially eliminated, and newer DOCSIS versions beyond DOCSIS 3.1 with higher speeds. Some equipment has automatic termination, others a physical switch, while the remainder requires a physical terminator (e.g. male XLR-5 plug fitted with a resistor) to be installed by the user. Does a television draw electricity while off? This is due to the fact that there are several factors to consider while ring ceramics in a kiln. However, upon AMC Networks achieving its independence of Cablevision, the channel was shut down due to low ratings. The CAN bus is also used as a fieldbus in general automation environments, primarily due to the low cost of some CAN controllers and processors.

KNX can link up to 57,375 devices using 16-bit addresses. KNX encompasses tools for project engineering tasks such as linking a series of individual devices into a functioning installation and integrating different media and configuration modes. Configuration may be achieved through a combination of local activity on the devices (such pushing a button), and active network management communication over the bus (peer-to-peer, or more centralized master-slave). Some modes require more active management over the bus, whereas some others are mainly oriented towards local configuration. The active error flag consists of six consecutive dominant bits and violates the rule of bit stuffing. The next four bits of the address are used to identify individual lines. Lines may be grouped together into an area, with up to 15 lines connected to a main line via line couplers. System devices and components (e.g. line couplers, backbone couplers). However, in the event of multiple failures of redundant computers, the A320 does have a mechanical back-up system for its pitch trim and its rudder, the Airbus A340 has a purely electrical (not electronic) back-up rudder control system and beginning with the A380, all flight-control systems have back-up systems that are purely electrical through the use of a "three-axis Backup Control Module" (BCM).

Installed systems can be accessed via LAN, point to point links, or phone networks for central or distributed control of the system via computers, tablets and touch screens, and smartphones. Segments connected with line repeaters can extend to a length of 4000 m and link up to 256 devices. The DLC field indicates the data length of the requested message (not the transmitted one). Each segment requires a local power supply and the maximum length of a segment is 1000 m. The lowest eight bits provide up to 256 addresses within one line, which can consist of up to four segments, each having a maximum of 64 (TP1-64) devices, or up to 256 (TP1-256) devices. Common versions of the CAN protocol include CAN 2.0, CAN FD, and CAN XL which vary in their data rate capabilities and maximum data payload sizes. In those scenarios, a low CAN bus use of around 30% was commonly required to ensure that all messages would meet their deadlines. It can use twisted pair (in a tree, line or star topology), powerline, RF, or IP links. KNX devices are commonly connected by a twisted pair bus and can be modified from a controller. Receiving: the CAN controller stores the received serial bits from the bus until an entire message is available, which can then be fetched by the host processor (usually by the CAN controller triggering an interrupt).

Many actuators include controller functionality, but also sensor functionality (for instance measuring operating hours, number of switch cycles, current, electrical power consumption, and more). It was the first electrical telecommunications system and the most widely used of a number of early messaging systems called telegraphs, that were devised to send text messages more quickly than physically carrying them. It is administered by the KNX Association cvba, a non-profit organisation governed by Belgian law which was formed in 1999. The KNX Association had 500 registered hardware and software vendor members from 45 nations as at 1 July 2021. It had partnership agreements with 100,000 installer companies in 172 countries and more than 500 registered training centres. The KNX standard has been built on the OSI-based EIB communication stack extended with the physical layers, configuration modes and application experience of BatiBUS and EHS. The communication system offers a reduced instruction set to read and write datapoint values. FHSS systems tend to disturb other types of wireless communication systems such as WiFi/WLAN. These functional blocks and datapoint types are related to applications fields, but some of them are of general use (such as date and time). Conveniently, the inverter-based welder comes with improved settings, which are easy to use and delivers both precision and performance.
