5.8.24 Pro-Storage Rev. A
The module Pro-Storage writes (or reads out) large quantities of data from an
ADbasic
process to an (exchangeable) storage medium. Therefore data can
be stored during stand-alone operation of the
ADwin
system at long-term mea-
surements. On the module there is a battery-backed real-time clock to dates-
tamp the data.
Storage media
The Pro-Storage module supports PCMCIA memory cards, Compact-Flash-
cards in combination with an adapter card as well as 1" and 1.8" hard disks.
Basically the storage media can be used with a reading device of a PC to read
out the data or write the data to the media. In any case, the medium must be
initialized by the program
<Pro-Storage.exe>
before using it.
The user must program writing to (or reading) the medium during operation in
a low-priority process. The process is running additionally to the already run-
ning open-loop, closed-loop or measurement processes; data is exchanged
via a global memory (FIFO). A standard example for such a low-priority pro-
cess is included in delivery, illustrating how to write data to the storage
medium.
The further module description is into the following sections:
General Operating Information
In any case, before using the storage medium it should be initialized with the
program
<Pro-Storage.exe>.
Do not remove the storage medium as long as data are accessed (left, lower
LED is blinking). As a consequence, the data exchange would be interrupted.
If data of the Pro-Storage module is processed differently than with the pro-
gram
Pro-Storage.exe
, for instance using a read access device, the follow-
ing items are to be considered:
1. The size of the files must not be changed.
2. The files must not be deleted or generated.
3. During the writing process the file end must not be exceeded.
4. The data has to absolutely remain in its physical position.
If the rules are not kept, the data will be overwritten or destroyed.
