This application allows any data points of a plant to be logged.
The description, the selected data points of all devices of a plant and the sample inter-
val are defined in the trend definition. With online trend, it is also possible to select
storage of the commissioning report at the start and end of the logging process. In off-
line trend, start and end of logging can be defined.
In trend logging, the cyclically queried data are stored and graphically presented. Ear-
lier trend logging can be retrieved and presented again at any time.
With the OZW10 and OZW111, the Trend application is only available online:
 Online Trend: The connection between plant and PC is established. All acquired
data are stored directly on the PC. The graphic presentation of trend logging takes
place online
 Offline Trend: There is no connection between plant and PC. All acquired data will
be downloaded and stored on the memory card in the central unit. The graphic
presentation of logging is made after uploading
Trend logging can be printed out and exported as an ASCII file.
