Ha-VIS Middleware, which provides easy and flexible integration of UHF RFID readers into plant-wide projects, is based on the open standard ALE 1.1 of the GS1 EPCglobal. This standard defines a number of useful functionalities including read/write operations, filtering and triggers. In addition, it clearly specifies how external software interacts with these functionalities. The standard guaranties a reliable, durable, well documented and testable system which is maintained and developed by the GS1 EPCglobal organisation.
The HARTING Ha-VIS Middleware meets ALE 1.1 and fully conforms to the current standard. Compared to the earlier ALE 1.0 standard, ALE 1.1 defines more useful functionalities, especially relating to how data is written into transponders. This conformity has now also been certified by GS1 EPCglobal.
