Go to the Step7 HW-Konfig window and click on the encoder symbol on the bus rail to select it. Bottom left in
the module window the various encoder modules are shown. Enter the interface properties with a double
click on the „Interface" module.
The „Synchronization"-Tab shows the assignment to a certain sync domain. As a PROFINET line may be
assigned to just one sync domain, this field is gray and not alterable.
Select the desired „RT-Class" from „RT" (Class 1) or „IRT" (Class 2 or 3). Together with setting „IRT" a further
selection is provided, choose „IRT Option" „high flexibility" (IRT Class2) or „high performance" (IRT Class3).
Settings should be made in accordance with the settings of the controller.
In Properties Tab „Application" a box can be checked if the encoder shall operate isochronously with the PLC
application. In real time classes „high flexibility" and „high performance" this is usually true.
Additionally, the point in time „Time Ti [µs]" can be selected when the encoder internally fetches its position
data, prior to the next send clock bus cycle. The parameter „Time To [µs]" is not relevant for the encoder and
will not be evaluated.
