)).
The IO-Link Master stores a maxiumum of 64 events.
The single events will be stored in a ring buffer. The AL1332 supports the following operation modes
for writing the ring buffer:
Overwrite Mode: If the buffer memory is full, the oldest event will be overwritten by new incoming

Acknowledge Mode: Events will only be overwritten, when they are read and acknowledged.
The configuration is done via sub-index 0x05. The eventsare stored in sub-indexes 0x06...0x46.

The IO-Link master supports the configuration of the connected IO-Link devices from the EtherCAT
projection software. The parameters of an IO-Link device are set via IO-Link index and subindex. The
number of the configurable parameters depends on the connected IO-Link device.
Available parameters of the IO-Link devices:
