Information relating to the transmitter and any dependencies in the device software.
Note!
•
Please read the information in the "Info" folder carefully before configuring.
Working with GSD files
The GSDs must be integrated into the automation system. Depending on the software
that is being used, the GSD files can be copied to the program-specific directory or can
be read into the database using the import function within the configuration software.

•
Copy the files into the subdirectory:
...\ siemens \ step7 \ s7data \ gsd.
•
The bitmap files also belong to the GSDs. These bitmap files are used to display the
measuring points in image form. Load the bitmap files into the directory:
...\ siemens \ step7 \ s7data \ nsbmp.
If you are using configuration software other than that referred to above, ask your PLC
manufacturer which directory you should use.
Configuration examples
The configuration of a PROFIBUS system is normally effected in the following manner:
1. The transmitters which are to be configured are integrated into the configuration
program of the automation system via the PROFIBUS network. The GSD file is used
here. Measured variables required can be configured offline using the
configuration software.
2. The automation system's user program will have to be programmed now. On the
one hand, the input and output data are controlled in the user program and on the
other hand the location of the measured variables is defined so that they can be
processed further. An additional measured value configuration module may have
to be used in the case of automation systems which do not support the IEEE-754
floating point format. It may also be necessary to change the byte sequence (byte
swapping) depending on the type of data management employed in the
automation system (little-endian format or big-endian format).
3. When configuration has been completed, this will be transferred to the automation.
4. The system can now be started. The automation system will establish a connection
to the configured devices. The device parameters which are relevant for the
process can now be set using a Class 2 master, e.g. with Commuwin II.
