Tip
When working with fieldbuses, parameter sets can also be switched to flash
and the memory card in cyclic operation. You can find further information on
this in the interface description of the MP85A process controller.
It typically takes less than 200 ms to enable a new parameter set. At very low
filter limit frequencies, the filter settling time must be added to this. If you use
digital inputs for switching, switchover occurs when the level changes at the
input (edge).
