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)
(
)). 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:

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.

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])
