Profibus Type Files (GSD Files)
Type files are computer files that some Programmable Logic Controllers (PLCs) use
to compile their Profibus programs. These files are device-specific and contain
information on features found in that device. Thus a different type file should be
defined for each Profibus device.
For older Siemens Profibus PLCs, the “type file” is proprietary to Siemens Energy &
Automation (SE&A); hence, SE&A must create the type file. Newer Profibus PLCs
use a non-proprietary equivalent of a “type file,” generally referred to as a “GSD file.”
AE does not create or supervise distribution of either kind of type files.
Type files are available on SE&A’s electronic Bulletin Board Services (BBS). You
can download the type files through a modem connection. The telephone numbers for
SE&A’s Profibus BBSs are:
• USA.: (423) 461-2751
• Europe: 49 911 737972
You can download type files from a World Wide Web site maintained by the Profibus
Trade Organization. The address is http:\\www.profibus.com.
Setting the Network Address with the Profibus DIP Switch
Use the DIP switch next to the Profibus port on the rear panel to set the Apex
generator's address. Allowable addresses are even numbers between 0 and 126,
selected in binary format.
To enter the unit's address, set the switch positions for binary representation, starting
with the switch on the left and proceeding to the right (descending order of
significance). The switches are numbered 1 through 8. Switch 1 is the most significant
byte (MSB), and switch 8 is the least significant byte (LSB).
