Acyclic Data
Acyclic data, such as device parameters or events, are exchanged using a specified
index and subindex range. The controller accesses these using Explicit Messaging.
The use of the index and subindex ranges allows targeted access to the device data
(for example, for reassigning the device or master parameters during operation).
If the port of the master is set to IO-Link mode, the IO-Link master attempts to
communicate with the connected IO-Link device. To do so, the IO-Link master
sends a defined signal (wake up pulse) and waits for the IO-Link device to reply.
The IO-Link master initially attempts to communicate at the highest defined
data transmission rate. If unsuccessful, the IO-Link master then attempts to
communicate at the next lower data transmission rate.
If the master receives a reply, the communication begins. Next, it exchanges the
communication parameters. If necessary, parameters that are saved in the system
are transmitted to the device. Then, the cyclic exchange of the process data and
value status begins.
Setting up a device for a specific application requires changes to parameter
settings. The device parameters and setting values are contained in the IODD of
the device.
IO Device Description (IODD) files contain information about the device
identity, parameters, process data, diagnostic data, and communication
properties. These files are required to establish communication with the sensors
via IO-Link.
The IODD consists of multiple data files; the main file and several optional
language files are in XML-format and graphic files are in PNG format (portable
network graphics). These files adhere to the IO-Link open standard, which
means that they can be used with any IO-Link masters.
IODD files are assigned using Studio 5000® and the 1734-4IOL Add-on Profile
(when using the 1734-4IOL IO-Link master module).
