Watson Marlow Pumps 700 Series, Инструкция по установке, эксплуатации и обслуживанию

Страница: 22 / 98

The 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.
Note : The data flow to and from the pump may need to be byte reversed, due to the differences of
handling between suppliers of master devices.
The GSD file, file name WAMA0F70.GSD can be found at our website wmftg.com.
User parameter data
The user parameter data is set by entering values into the 'Ext_User_Prm_Data_Const (0)' line of the GSD
file. This is indicated below and the relevant bytes are listed in the table. No further changes should be
made to the GSD file and Watson-Marlow accepts no responsibility for the pump failures arising from the
changes to the GSD file.
