How does actuator sensor interface work

This high number of users has been reached because the technology is freely accessible to all device manufacturers and developers. AS-Interface is a real alternative to conventional network solutions. For example, it can be used as a partner network for higher-level systems such as Profibus, DeviceNet or Interbus. The AS-Interface already is being used for automation processes, packaging machines, process control valves, filling installations, electrical distribution systems, elevators and in the field of food production.

AS-Interface also offers advantages from the point of view of security. Linkages with safety hardware such as emergency off switches, light curtains and door lock systems can provide a safety integrity level SIL of 3. The AS-Interface was already developed between and in cooperation with 11 companies that merged to become AS-international. The first functioning system was presented a short time later at the Hannover Messe.

In its original form , version 2. This corresponds to inputs and outputs. Important functions such as automatic single node replacement were already a part of the system. AS-Interface is a master-slave bus, with a single master controlling up to 62 slaves.

The main benefits of AS-Interface are its simplicity, low cost, and high speed. Up to 62 AS-I slaves can be controlled by one master when the extended addressing system is used.

And each slave can have 8 inputs and 8 outputs, for a total of inputs and outputs. AS-Interface masters. Simplified system installation by means of AS-Interface wiring system AS-Interface - perfectly complements for different field buses or industrial Ethernet Graphic user interfaces for clear configuration and diagnostics High-performance controllers and gateways.

Actuator-Sensor Interface AS-i The actuator-sensor interface AS-i is a manufacturer-independent standard for connection of actuators and sensors of the first field level. Your browser is out of date! The time to set an output is calculable with great accuracy. And there are other attractions to AS-Interface including a simplicity not found in any other industrial network, device power right on the network cable and no need for Master or Slave Programming.

There are no system parameters to set and devices are configured simply by identifying their device ID to the AS-Interface Master. AS-Interface is a very important technology, not only because it addresses the lowest level of a control system architecture, but also because it is backed by Siemens, the worldwide leader in Industrial Control. This gives it an automatic advantage in the marketplace.

AS-Interface will be successful for many of the same reasons that systems like DeviceNet have been successful; strong momentum and the backing of a vendor with a huge installed base.

All these bus systems are more costly, support more generic communications, provide advanced diagnostic functionality and are highly configurable. These systems support very sophisticated, intelligent devices with tremendous data capabilities. The AS-Interface master automatically detects invalid slave transmissions and schedules repeats.

Masters can interrogate the network to identify connected slaves or receive an external list of slave addresses. AS-Interface Masters automatically monitor system voltage levels and slave operation and report this data to the controller. Limited support in V1 and V2.

The choices vary in time-to-market, supportability, resource requirements and price. An off-the-shelf serial gateway is the least economical approach with the fastest time-to-market. Data from your product will transfer to the gateway at serial baud rates
