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 object sequence for process data exchange via IF2 depends on the object sequence
from IF1; see "List of drive objects" (p0978).
The factory setting of p8839[0.1] = 99 enables the implicit assignment (see previous table).
An alarm is generated in case of invalid or inconsistent parameterization of the assignment.
