Properties of the cyclic interfaces IF1 and IF2
The following table shows the different features of the two cyclic interfaces:

For parallel operation of the hardware interfaces and the explicit assignment to the cyclic
interfaces IF1 and IF2, the new parameter p8839[0,1] "PZD Interface hardware assignment"
exists for the device IO in the expert list.
The default setting of p8839[0,1]=99 enables the implicit assignment (see table above).
An alarm is generated in case of unvalid or inconsistent parameterization of the assignment.
Note
Parallel operation of PROFIBUS and PROFINET
Isochronous applications can only run via the cyclic interface IF1. With an additional
PROFINET module plugged in, there are two parameterization options:
- p8839(0) = 1 and p8839(1) = 2: PROFIBUS isochronous, PROFINET cyclic
- p8839(0) = 2 and p8839(1) = 1: PROFINET isochronous, PROFIBUS cyclic
