5.4.2 Configure
It is possible to select on the master which modules are to be
involved in cyclic data transfer. Modules and slots always relate to
each other. Empty spaces (empty modules) therefore have to be
configured for modules to be excluded.
The target configuration is defined in the form of identifiers. The
identifier is stated in the last column in for every defined module.
The identifiers of the modules have to be listed after each other in
ascending order. If the data of a module is not to be involved in
cyclic data transmission, then an empty module must be config‐
ured at this point.
5.5 Extended diagnostics
(from the 7th byte)
The pump uses the mechanism of the extended PROFIBUS
®
diag‐
nostics to report error statuses to the master. The extended diag‐
nostics can be found in the diagnostics telegram. The extended
diagnostics includes the device-related "Alarm_Type (48)" and the
"Diagnostic_User_Data".

Diagnostic_User_Data consists of a minimum of one group of 3
bytes with error information. Diagnostic_User_Data consists of a
maximum of 19 groups. The error information of a group is coded
as follows:
