6.5 Data memory
At Endress+Hauser, the term HistoROM refers to various types of data storage modules on which
process and measuring device data is stored. By plugging and unplugging such modules, device
configurations can be duplicated onto other measuring devices to cite just one example.
6.5.1 HistoROM/S-DAT (sensor-DAT)
The S-DAT is an exchangeable data memory in which all sensor relevant parameters are stored, i.e.,
diameter, serial number, calibration factor, zero point.
6.5.2 HistoROM/T-DAT (transmitter-DAT)
The T-DAT is an exchangeable data memory in which all transmitter parameters and settings are
stored.
Storing of specific parameter settings from the device memory (EEPROM) to the T-DAT module and
vice versa has to be carried out by the user (= manual save function). Detailed information about
the procedure → ä 90
6.5.3 F-CHIP (Function-Chip)
The F-Chip is a microprocessor chip that contains additional software packages that extend the
functionality and application possibilities of the transmitter.
In the case of a later upgrade, the F-CHIP can be ordered as an accessory and can simply be plugged
on to the I/O board. After start up, the software is immediately made available to the transmitter.

Caution!
To ensure an unambiguous assignment, the F-CHIP is coded with the transmitter serial number
once it is plugged in. Thus, it can not be reused with other measuring devices.
