Example for selecting the GSD file
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. The following example describes
the use of the t-mass 65 GSD file (complete functionality) for
PROFIBUS PA
:
Select the t-mass 65 GSD file in the measuring device by means of the SELECTION GSD function.

SELECTION GSD
Select: MANUFACT. SPEC.
1.
Before configuring the network, load the t-mass 65 GSD file into the configuration system/
master system.
!
Note!
When installing the GSD file, always first use the GSD file with the extended format
(EH3
x
1545.gsd). However, if the installation or the configuration of the device fails with this
format, then use the standard GSD (EH3_1545.gsd).
Example for the configuration software Siemens STEP 7 of the Siemens PLC family
S7-300/400:
Use the t-mass 65 GSD file with the extended format (EH3x1545.gsd).
Copy the file to the subdirectory …\ siemens \ step7 \ s7data \ gsd.
The bitmap files also belong to the GSD 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.
2.
t-mass 65 is a modular PROFIBUS slave, i.e. the desired module configuration (input and
output data) must be performed in the next step for t-mass 65. This can be done directly by
means of the configuration software.
A detailed description of the modules supported by the measuring device can be found on
6.5.3
Maximum number of writes
If a non-volatile 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 non-volatile device parameters via the PROFIBUS!
