7.20 Trend ASM
7.20.1 General
Using this application-specific automation module (ASM), the application controller can record up to five
independent values over a configurable period. The recordings are saved in the devices. They can be
displayed on the web user interface and exported from there.
The values to be recorded must be sent via output sockets on other ASMs linked to the input sockets on
this module. The values can therefore be telegram or signal values that are transmitted by KNX or BACnet
to other ASMs and are then forwarded by these for recording. The Trend ASM itself does not have any
group objects or BACnet objects.
The data point type is freely selectable for each input value. The recording duration and the recording
frequency are set to suit the required application.
The Trend ASM has a ring memory that automatically deletes the oldest entries. If a recording duration of
1 year is selected, for example, recordings that are older than a year are automatically and irrevocably
deleted.
The value valid at the selected measuring times is always saved. Different values between two measuring
times are not saved.
The recordings are retained after a power failure and after a device restart.
It is essential the clock in the application controller is set to operate this module.
