Bihl+Wiedemann reports that it’s reintroducing its AS-i Analyzer diagnosis and analysis tool as “Version Innovation Step 2” with new functions, including improvements to its operator guidance capabilities. The company says AS-i Analyzer still makes error detection and permanent monitoring of AS-i networks easy and comfortable. It supervises and evaluates a network’s entire telegram traffic without intervening. Results are analyzed and displayed on a notebook or a PC.

However, the new analyzer’s LED traffic lights allow the network to be checked without help from an attached notebook. If fundamental disturbances on the network are registered after switching on the analyzer, then users can percept without the notebook.

In addition, AS-I Analyzer’s definition and determination of “consecutive errors“ establishes a rational basis for a network’s evaluation. It describes for each slave how often a telegram had to be consecutively repeated before getting a valid response telegram. The company adds its improved analyzer and new functions are suitable for: search of errors; creating a protocol that contains the network and its quality; detailed diagnosis of the network; and analyzing Safety-at-Work networks and applications.
