IE/AS-i LINK PN IO

■
Application
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). The 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 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.
