The DP/AS?i Link PN IO is a PROFINET IO device (according to IEC 61158 / IEC 61784) and an AS?Interface master (based on AS?Interface Specification V3.0 according to IEC 62026?2). It enables transparent data access to AS?Interface from Industrial Ethernet.

Exchanging data with PROFINET IO controllers

PROFINET IO controllers can exchange I/O data with AS?Interface in cyclic mode and can perform AS?i master calls in addition with acyclic services (e.g. reading/writing the AS?i configuration during normal operation). IE/AS?i Link PN IO is, therefore, suitable for distributed configurations and for integrating a lower-level AS?Interface network.

Single master

The AS?i single master version of IE/AS?i Link PN IO is suitable for applications with typical volumes of data. The single master can operate up to 248 DI / 248 DO, using 62 A/B slaves with 4 DI / 4 DO each.

Double master

The AS?i double master version of IE/AS?i Link PN IO is suitable for applications with large volumes of data. In this case, twice the volume of project data can be used on two AS?i lines running independently of each other. The double master can operate up to 496 DI / 496 DO, using two AS?i networks each with 62 A/B slaves with 4 DI / 4 DO each.

Wireless communication

Using an upstream IWLAN client module, e.g. SCALANCE W748?1 RJ45, an AS?Interface line can be wirelessly integrated into the PROFINET world.

Sample uses are applications which up to now have been performed with fault-prone tow chain or collector wire technology. Maintenance costs are thus reduced.
