Exchange acyclic process data
5244
IO-Link allows up to 32-byte process data in one IO-Link device. The connection of IO-Link devices
with process data > 4 words is not the focus of the AS-i IO-Link gateway. Nevertheless access to
these process data via the acyclic write / read requests described here is possible. Furthermore
access to the process data are also possible for a configuration software, irrespective of the AS-i
master used.
NOTE
► Data set acyclically also have to be reset acyclically!
Data set acyclically remain even if communication is interrupted.
Cyclic writing of data overwrites acyclically set values.
