Note:
Updating the firmware is only possible when
the transducer and a PC computer are connected
directly (no other Master devices can be connected using
the RS-485 interface).
Note:
Switching off the power supply during the firmware
updating process may result in an unrepairable damage
to the transducer
5. . Archiving measured values
5. .1. Transducer memory structure
Standard P30U transducers (regardless of the manufactu-
ring variant code) are equipped with a 4MB internal memory for storing
data recorded by the transducer. The default recorded parameter is
the displayed value, that is the measured value or value converted using
mathematical functions and individual input characteristic. It is also
possible to additionally record the second displayed value or displayed
values and all queried values if RS-485 interface works in
Master
or
Monitor
mode. The internal transducer memory enables storing
534,336 records. The memory is of circular buffer type. After the memo-
ry becomes full, the oldest data is overwritten. The internal archive can
be read, copied and cleared.
Transducers in P30U-X1XXXXXX variants are equipped
with an SD/SDHC memory card slot enabling writing archive data to files
on the external SD/SDHC memory card.
Transducers in P30U-X2XXXXXX variants are equipped
with an 8GB internal file system memory (the capacity of the file system
memory can be increased on a special order or due to manufacturer’s
needs) where the data from the internal memory are automatically
copied to files. Data can be downloaded via the Ethernet interface using
the FTP protocol.
