2.9 Read-out of data
In addition to automatic read-out via the external CompactFlash memory card,
measurement data can also be read out through one of the interfaces (RS232,
RS485, setup, Ethernet).
Both read-out options (card/interface) work in parallel. For this reason, there
are also two “digital signals”, which indicate when the available storage space
has fallen below a certain configurable value.
Memory alarm The limit for alarms can be set by the parameter Configuration ➔ Device data
➔ Memory alarm in the configuration level.
The parameter Configuration ➔ Memory upload can be used to determine
which storage space indication should be shown in the status line. The “digital
signals” for storage space detection function independently of the indication in
the status line.
Digital signals IntMemAlm/CF
If this signal is set, it means that no data have been fetched by the CF card for
a long time, and the available capacity of the internal memory has fallen below
the configured level.
IntMemAlm/ser
If this signal is set, it means that no data have been fetched by the interface for
a long time, and the available capacity of the internal memory has fallen below
the configured level.
MemAlmCFcard
If this signal is set, it means that not enough space is avialable on the CF card.
The program PCA3000 can help here. Use PCA3000 to read in the data, save
them to the hard disk on a network, and free up the space on the CF card.
Alternatively, you can use a new CF card.
Data lost A loss of data is only imminent if all three of the above signals are set.
Read-out via
interface Use the PCA Communications Server software (PCC) to read out
measurement data via the serial, setup or Ethernet interface. The software has
been developed especially for the paperless recorder.
v Please refer to the Operating Manual 59500 for further information.
2.10 Evaluating data
Please use the PC Evaluation Software (PCA3000) for evaluating the data on
the PC. The software has been developed especially for the paperless
recorder.
v Please refer to the Operating Manual 59498 for further information.
H
Use the same archive (in the PC) for reading out via the interface
as for reading out with the CF card. This saves having to put
together data from different files at a later date.
