836P Pressure Sensor with IO-Link Overview Chapter 1
Start up of the I/O System
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.
Assign Device Parameters
A device that is built for a specific application requires changes to parameter
settings. The device parameters and setting values are contained in the IODD
of the device.
I/O 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 (AOP).
