8.5 EtherNet/IP: Configure IO-Link devices
23106
The AL1122 supports the configuration of the connected IO-Link devices from the EtherNet/IP
projection software. For this, ifm offers the EtherNet/IP object "IO-Link Request" (→ IO-Link requests
(object class: 0x80) (→ p. 97)). The object enables direct read and write access to IO-Link objects of the
IO-Link device. The extent of the configurable parameters depends on the IO-Link device.
The following services are available:
Name
Description
Reference
Read request
Send a request to read an IO-Link object
→ Read_ISDU (→ p. 98)
Write request
Send a request to write an IO-Link object
→ Write_ISDU (→ p. 101)
Information for the execution of acyclic commands: → Execute acyclic commands (→ p. 49)
Available parameters of the IO-Link devices: → Operating instructions of the IO-Link device

8.6 EtherNet/IP: Programmers' notes
23323
The programmer can access the following data from the PLC application:
 Read cyclic input and output data of the IO-Link devices
 Read diagnostic and status information
 Change parameters of the IO-Link port of the AL1122
 Read and change parameters of the connected IO-Link devices
The following sections show the available options.

8.6.1 Read cyclic input data
8518
The user can access the cyclic input data of the connected sensors and IO-Link devices via the
controller tags of the AL1122.
To access the input data:
► Starting RSLogix5000.
► Open a EtherNet/IP project.
► In the project tree: Mouse click on [Controller Tags] > [AL1122.I]
> The window shows the data structure with cyclic input data ([AL1122.I:Data])
