2.10 Acyclic communication

Default unit selection of Totalizers
The device provides the possibility to select units for each
totalizer type.
Units are only valid for PROFIBUS, local HMI display units
will not be changed.
Select object properties and then Parameter assignment.

Acyclic Addressing
Each parameter in a PROFIBUS slave is mapped to an address specified by slot and index.
The slot number refers to an array of data. The index tells you where in the array the data you
want starts.
