In this state, only the following parameters can be configured:
– Start time [TiStt] and stop time [TiStp]
– Record count [RecCnt] (can only be overwritten with 0: delete log
buffer)
– Notification threshold [NotifThd]
The record count [RecCnt] can only be overwritten with 0. This deletes all the
log data. After a write operation of 0, there is one entry showing the log status
(record count = 1).
It is not possible to reload sampled data into the CFC Editor.
With a full loading procedure, any previously sampled data will be lost. With
differential or delta loading the data will not be lost.
The PXM20 stores modified parameters in its internal memory cache. To
display the data actually written, you must exit from the trend log object and re-
select it.
11.3 Processing trend data in Desigo CC
The Trends application in Desigo CC lets you create and display online trends
and offline trends. You can save, query, delete, edit and save trend data in
Trend Views.
You can display the trend data in the Trend Viewer any time, even if Desigo CC
is not connected to the site (no real-time data is available).
