ASi Bus Protocol
The ASi master communicates with the other nodes in the ASi network. In an ASi-3 network, the telegram consists of 4-bit user data. In an ASi-5 network, there are typically 16 bits available for cyclic transmission – but profiles also exist with up to 32 bytes per node. Communication takes place using a serial transmission protocol for standard data. In the case of safety-related data, this is transmitted via a dynamized secure protocol. The AS-Interface telegram is absolutely interference-free. The data is always transmitted reliably even in harsh environments.
ASi Bus Topology
Thanks to the ASi cable and the piercing technology, the ASi bus system makes it easy to create junctions at any point in the system. The ASi Bus topology is freely selectable, e.g. tree, ring, star or line structure.
The open ASi bus system is suitable for use in all four areas of industrial automation technology:
An ASi network consists of four components: the ASi master, the ASi nodes, an ASi power supply and the yellow ASi cable:
ASi Bus addressing is performed either directly via the master, an ASi Bus adress programming device, or via the commissioning wizard integrated in the Bihl+Wiedemann Software Suites.
Simple Addressing Using the Commissioning Wizard
Our intuitive commissioning wizard offers the easiest way of addressing. It can be used to identify, address and parameterize all hardware components on the ASi bus. As part of the Bihl+Wiedemann Software Suites (BW2916, BW3065), the Commissioning Wizard is suitable for configuring and addressing all devices automatically, and guides the user step by step through the addressing process.
Faults in ASi networks can be identified and corrected quickly and easily using special diagnostic software. The software is mainly used for commissioning and maintenance intervals and provides both specific and detailed information on errors that have occurred and concrete recommendations for solutions. If an error occurs, it is clearly displayed in the software screen. Therefore, even inexperienced ASi users receive direct "assistance for self-help".
The ring buffer facilitates troubleshooting and enables continuous measurements for up to 24 hours over a period of up to one week.
