The screen will state running or stopped, depending on how the user has set up the fail-
safe function within the PROFIBUS GSD file (see "PROFIBUS GSD file" below ). The
MODE
button gives access to the PROFIBUS settings and the station address. When the menus are
accessed, the pump is still in PROFIBUS bus mode but with no communications.
After five minutes of inactivity the pump will revert back to the home screen and discard
any unsaved changes, if there are still no communications then the BUS ERROR screen will
be displayed.

PROFIBUS GSD file
The qdos PROFIBUS pump can be integrated into a PROFIBUS DP V0 network using a
General Station Data (GSD) file. The file identifies the pump and contains key data
including its communication settings, the commands it can receive and the diagnostic
information it can pass to the PROFIBUS master on interrogation.
The GSD file— file name WAMA0E7D.GSD— can bedownloaded from the Watson- Marlow
website and installed; or typed into a PROFIBUS master directly from this manual using a
GSD editor program.
Note:
The data- flow to and from the pump may need to be byte- reversed, due to
differences of handling the data between suppliers of master devices.
The GSD file, filename: WAMA0E7D.GSD
