4. To insert a PROFIBUS communication interface on the controller, select the
Hardware object, placed below the AC 800M controller.
5. Right-click with the mouse and select New Object in the context menu.
6. Browse to the required communication interface, e.g. CI854 for PROFIBUS.
7. Enter the CEX bus number of the module placed, for example 1, in the name
box.
8. Click Create.
9. Repeat steps 5 to 8 until all of the desired modules have been placed.

DTMs exchange data with field devices using acyclic communication (DPV1).
CI854(A) supports this type of communication, although CI851 does not.
The CEX bus is the internal communication bus for data transmission between
AC 800M controller and the connected communication interfaces. The
communication interfaces are located on the left side of the controller and are
numbered from right to left. Starting number is 1.
Example:
If the CI854 module is the second module on this bus, the number 2 must be
entered in the name box.
The settings for the PROFIBUS master are listed in the product documentation of
CI854, AC 800M, PROFIBUS DP Configuration (3BDS009030*).
