IO-Link Interface
3.5 Process data
There are each 4 bytes of process data available per direction. The number can not be
changed.
For each process data object a maximum of 4 objects can be mapped.
The data direction is described from the view of the process control (PLC, IPC, ...).
Process output data (PD out) are data from the control to G6.
Process input data (PD in) are data from G6 to the control.
To activate the process data objects in the device, it is necessary to set the mapping of
the process data by using the parameters defined in chapter 3.
The writing of the process output data (2 * 2 byte) and reading of process input data (2
* 2 byte) results in a cycle time of 18.4 ms.
If via the IO-Link master command (value 0x99) the output process data is set invali-
dated, the processing of the output process data in the power unit is stopped (PD out
count is set to 0).
At switched off power unit, the last received PD in process data are sent. In addition, an
event is generated, which marks the invalidity of the process data.
The number of the performed process data accesses is illustrated in the following pa-
rameters:
