ACS offline trend compatibility

Offline trend definitions from ACS V9.00 or older can still be written to OZW, run
there and read.
Trends are listed on the OZW trend overview page, but cannot be exported or
edited there. They are displayed in gray on the overview page and the buttons are
hidden.
A struck out pencil symbol indicates that this trend cannot be edited in OZW. These
trends may only be operated via ACS.
The interval cannot be displayed in this case and is displayed with "?".
For ACS V9.00 or older, the web-defined trends cannot be read and are therefore
unavailable. ACS writes its trend definitions to the first, as viewed from ACS,
available trend channel. As a result, a web-defined trend can be overwritten without
warning.
As of ACS V9.01, the ACS and OZW trend definition is compatible. The trends can
be defined or edited in ACS or OZW.
The trend in OZW synchronizes if an explicit start time is selected in ACS when
defining the trend, similar to the trends defined in OZW using the interval grid (see
Section 9.2.1).
No synchronization occurs if a trend is started in ACS with "Start now".
When editing an ACS trends in OZW (as of version 6), unknown trend intervals are
set to the default interval of 15 min.
A trend created in OZW or as of ACS V9.01 cannot be edited or displayed with
ACS V9.00 or older versions.
Write trends defined in ACS via ACS to OZW (and not trend export/import).
