Ease of Operation

AS-i = easy: Only one cable for both data and energy is required. The reduced cable length supports reduced time expenditures for mounting and installation. Also engineering via drag & drop within the engineering framework of the Totally Integrate Automation Portal is extremely clever. In addition, perfect diagnostics options are offered. Moreover, AS-i supports easy on-site fault rectification and maintenance on the basis of connections which can be rapidly removed without interrupting the field bus thanks to the insulation displacement method.

Only one cable for data and energy

The enormous wiring costs caused by a higher degree of automation and the resulting additional fault sources represented an important reason for the development of AS-Interface. Increasingly complex processes with a multitude of digital and analog measured values had to be centrally bundled and processed in the control. The strategy of AS-i focused on the reduction of cable harnesses while still serving the increasing demand for control and diagnostics data on the control level.
The cost advantages offered by AS-Interface are substantial: Accordingto a survey carried out by the TU Munich, for example more than 25 % of electrical automation costs can be saved when employing AS-Interface with a milling machine. This is owed to the fact that fewer cables not only result in reduced mounting and commissioning times, but also in minimized advance configuration expenditures. As a major advantage for ongoing operation, standstills can be reduced or even completely prevented through eased assembly and additional diagnostics information.

Time-saving mounting / installation

The two-pole AS-i cable is routed throughout the system and connected to the control’s AS-i master. It both ensures the sensors’ and actuators’ data transmission and energy supply – while offering a high degree of protection as all slaves are docked onto the system on the basis of the innovative insulation piercing method.
This is how it works: The modules’ contact mandrels pierce the cable’s insulation and establish safe contact with the copper conductors – ensuring maintenance of the high degree of protection. When the mandrels are pulled out during removal of a slave, the holes automatically close at ther espective position due to the cable’s “self-healing power” and thus restore the insulation. A further safety aspect: The cable’s geometry ensures reverse polarity protection.
No other bus system can be connected to the control and routed through the system faster while being equippedwith I/O modules and AS-i slaves at the relevant positions.

Engineering in the Totally Integrated Automation Portal (TIA Portal)

The Totally Integrated Automation Portal represents an innovative engineering framework for all automation tasks. As central component of TIA, the TIA Portal facilitates redefined engineering.
The TIA Portal combines control programming and visualization configuration and integrates the parameterization of drives and networks as well as the programming of fail-safe applications.
The TIA Portal supports very intuitive operation. For instance, configuration can be easily realized via the hardware catalog by means of drag & drop, after which a realistic representation of all network slaves and components is output – right down to the actuator/sensor level.
Furthermore, the engineering framework supports easy getting started with safety programming via a library with certified safety functions.
The TIA Portal not only enhances your workflows’ efficiency, but also sustainably improves your productivity and competitiveness – no matter in which sector.

Comfortable maintenance

The online diagnostics in the TIA Portal provides accurately timed information on the slave to be exchanged in plain text. In addition, visual diagnostics information in network and device view and current status messages (operation, fault, maintenance) are provided.
The innovative AS-i insulation piercing method also accelerates device replacement within the scope of maintenance – without interruption of the AS-i bus. Replacement can thus be easily realized even by untrained staff. Moreover, the implementation time for expansions is reduced, allowing for minimized downtimes.
