Selecting the GSD file in the measuring device
Depending on which GSD file is used in the PROFIBUS master system, the corresponding GSD file
has to be configured in the device by means of the SELECTION GSD function.

Example
Before configuration takes place, a decision should be made as to which GSD file should be used to
configure the measuring device in the PROFIBUS master system. Below, the use of the
manufacturer-specific GSD file (complete device functionality) is shown using PROFIBUS PA as an
example:

Note!
When installing the GSD file, always first use the GSD file with the extended format
(EH3x1528.gsd). However, if the installation or the configuration of the device fails with this
format, then use the standard GSD (EH3_1528.gsd).

Example for the configuration software Siemens STEP 7 of the Siemens PLC family
S7-300/400:
Use the GSD file with the extended format (EH3x1528.gsd). Copy the file to the subdirectory
"…\siemens\step7\s7data\gsd". The GSD files also include bitmap files. These bitmap files
are used to display the measuring points in image form. The bitmap files must be saved to the
directory "…\siemens\step7\s7data\nsbmp".

If you are using configuration software other than that referred to above, ask your PROFIBUS
master system manufacturer which directory you should use.

The measuring device is a modular PROFIBUS slave, i.e. the desired module configuration
(input and output data) must be performed in the next step. This can be done directly by means
of the configuration software.

6.5.3
imum number of writes
If a nonvolatile device parameter is modified via the cyclic or acyclic data transmission, this change
is saved in the EEPROM of the measuring device.
The number of writes to the EEPROM is technically restricted to a maximum of 1 million. Attention
must be paid to this limit since, if exceeded, it results in data loss and measuring device failure. For
this reason, avoid constantly writing nonvolatile device parameters via the PROFIBUS!
