Parameter p8839[0,1] is used to set the parallel operation of the hardware interfaces and the
assignment to the cyclic interfaces IF1 and IF2 for the Control Unit drive object.
The sequence of objects is in line with p0978 (list of drive objects) for both interfaces.
The factory setting of p8839[0,1] = 99 enables the implicit assignment (see table above).
An alarm is generated in case of invalid or inconsistent parameterization of the assignment.
Note
Parallel operation of PROFIBUS and PROFINET
Either the isochronous mode or the PROFIsafe functionality can be assigned to an interface
via p8815 (IF1 or IF2).
p8815[0] = 1: IF1 supports the isochronous mode.
p8815[1] = 2: IF2 supports PROFIsafe.
arameter assignment options are possible if additionally the PROFINET module
CBE20 is inserted in the CU320
-2 DP:
p8839[0] = 1 and p8839[1] = 2: PROFIBUS isochronous, PROFINET cyclic
p8839[0] = 2 and p8839[1] = 1: PROFINET isochronous, PROFIBUS cyclic
