9.3.10 Accessing IO-Link devices
The device supports the following ISDU communication mechanism. Via ISDU (Indexed Service Data
Unit), the user can acyclically access parameters, process data as well as status and diagnostic
information of the connected IO-Link devices.
Access takes place via index and subindex of the respective object.
A separate area for processing acyclic commands is available for each port.
Availability data of the IO-Link device: Ò IO Device Description (IODD) of the IO-Link device
The following methods are available for acyclic access to the objects of the IO-Link device:
• Using ADS over EtherCAT (Ò/55)
• Using CANopen over EtherCAT (Ò/56)
9.3.11 Reading IO-Link events
The device supports IO-Link events.
IO-Link events are stored in the diagnosis history (0x10F3): Communication Area (0x1000 - 0x1FFF)
(Ò/64)
The IO-Link master stores max. 32 events.
The individual events are stored in a ring buffer. The device supports the following operating modes
for writing the buffer.
• Overwrite Mode: If the buffer is full, the oldest event is overwritten.
• Acknowledge Mode: Events are only overwritten when they have been read and acknowledged.
The operating mode is configured via the flags (0x10F3, subindex 0x05). The events are stored in the
subindices 0x06…0x26.
9.3.12 Using acyclic services
The device supports the following mailbox services for acyclic read and write access:
• Using ADS over EtherCAT (Ò/55)
• Using CANopen over EtherCAT (Ò/56)
9.3.12.1 Using ADS over EtherCAT
The device supports mailbox communication via ADS over EtherCAT (AoE). The AoE protocol allows
uninterrupted acyclic access to the connected IO-Link devices during normal operation. Access via
AoE to the IO-Link master is not supported.
AoE uses the object area 0xF302 for read and write access.
u Observe the TwinCAT help!
The following function blocks are available for access:
• ADS read: Read access
• ADS write: Write access
With AoE, IO-Link parameters with a length of max. 80 bytes can be read or written.
Notes on the input assignment of the ADS function blocks:
