6.3.2 Object List (OV)
The FMS services “Read” and “Write” can be used by the FMS master to
access objects defined in the object list (OV).
The ET 200U(DP Standard/FMS) always generates the full object list, even
in a mixed configuration or as a combi–slave.
The individual objects of the ET 200U(DP Standard/FMS) are addressed via
an index in the static object list. The following table illustrates how the ob-
ject list of the ET 200U(DP Standard/FMS) is structured.
