Technical data
HistoROM
data management
There are different types of data storage units in which device data are stored and used by the device:
Device memory
Available data • Event logbook such as diagnostic events
for example
• Parameter data record backup
• Device firmware package
• Driver for system integration for
exporting via Web server, e.g:
GSDML for PROFINET
Storage location Fixed on the user interface board in the
connection compartment
256
• Export the Heartbeat verification log (PDF file, only available with the "Heartbeat
Verification" application package)
• Flash firmware version for device firmware upgrade, for instance
• Download driver for system integration
• Visualize up to 1000 saved measured values (only available with the Extended
HistoROM application package →  260)
Web server special documentation →  262
The measuring device features HistoROM data management. HistoROM data management
comprises both the storage and import/export of key device and process data, making
operation and servicing far more reliable, secure and efficient.
When the device is delivered, the factory settings of the configuration data are stored
as a backup in the device memory. This memory can be overwritten with an updated
data record, for example after commissioning.
Additional information on the data storage concept
T-DAT
• Measured value logging ("Extended
HistoROM" order option)
• Current parameter data record (used
by firmware at run time)
• Peakhold indicator (min/max values)
• Totalizer values
Attachable to the user interface board in
the connection compartment
Data backup
Automatic
• The most important device data (sensor and transmitter) are automatically saved in the
DAT modules
• If the transmitter or measuring device is replaced: once the T-DAT containing the
previous device data has been exchanged, the new measuring device is ready for
operation again immediately without any errors
• If the sensor is replaced: once the sensor has been replaced, new sensor data are
transferred from the S-DAT in the measuring device and the measuring device is ready
for operation again immediately without any errors
• If exchanging the electronics module (e.g. I/O electronics module): Once the electronics
module has been replaced, the software of the module is compared against the current
device firmware. The module software is upgraded or downgraded where necessary. The
electronics module is available for use immediately afterwards and no compatibility
problems occur.
