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
