What is ASi bus system?
The ASi bus system comprises four components: the ASi master, an ASi power supply, the yellow ASi cable and the ASi nodes . This is a two-core, unshielded cable through which power as well as functional and safety signals are transmitted. It eliminates the need for complex parallel wiring.
What is ASi cable used for?
What is an ASi cable? The cable used for AS-Interface is an unshielded, non-twisted, two-wire yellow flat cable that can be connected with reverse polarity protection. It serves simultaneously for the transmission of ASi communication and to supply power to field devices with low power requirements.
What is an ASi block?
ASI introduces miniature terminal blocks. November – Carlisle, Pa – With a current rating up to 15 amps at 300 volts and a wiring capacity of 30 to 14 AWG, these micro miniature terminal blocks are available in single level, multiple wire and dual level designs.
What is ASi system?
Actuator Sensor Interface (AS-Interface or ASi) is an industrial networking solution (physical layer, data access method and protocol) used in PLC, DCS and PC-based automation systems.
What is ASi 5?
ASi-5 is the latest innovation stage of AS-Interface (ASi), a globally standardised fieldbus system for the first automation level. ASi connects sensors and actuators with a controller via a single two-conductor profile cable. The yellow ASi cable transmits power and data at the same time.
What is ASi?
Tip. In architecture, the ASI definition is “architect’s supplemental instruction.” Architects use it to request design or construction changes that won’t affect the cost or time of a project.
What is the Fieldbus Standard AS-Interface ( ASi )?
AS-Interface: The fieldbus standard AS-Interface (ASi) is used for communication within automation technology and is a supplement to the conventional standard fieldbus systems. With ASi, various field devices, such as sensors and actuators, can be integrated into a controller at the lowest automation level. But what exactly is AS-Interface?
What is the topology of an AS-Interface network?
The topology of the AS-Interface network is completely open enabling the user to install the system in a layout that best Þ ts each application. Due to its r obust operating principle, ther e ar e no limits to the structur e and any network topology can be used.
What can I do with an ASI cable?
ASi permits any bus topology. The total cable length is limited, but can be increased using repeaters, bus terminators or extenders. When errors occur, diagnostic devices or masters with built-in diagnostics functions help to locate them in the network.
What is the maximum length of an as-I Bus?
Topology of the AS-i Bus The topology of the AS-i bus is unrestricted. The lack of restrictions enables the most direct connections to be made between the bus and the various sensors and actuators in an installation. The maximum length of the AS-i bus is 328 feet (100 m) (including main runs and tap-off runs).
