12 Fieldbus interface
12.1 General notes
The PR 5410 can be turned into a field bus slave by inserting a field bus interface card .
This enables one or more devices to be included under a communication master (e.g.,
Siemens S7 ProfiBus).
The update rate is 50 ms.
The interface is configured under -[Fieldbus parameter] in the device. The
corresponding field bus protocol (in this case: ProfiBus-DP) is shown.
The field bus exchanges its data cyclically with each slave. That means: In each cycle, the
entire data range is written and read, even if there are no changes to the data content.

12.2 Scale protocol (8-byte) for the "Standard" application
The interface works with an 8‑byte write window and an 8‑byte read window for each
weighing point.
Note:
All fieldbus data is only valid, if 'Read_Value_Selected' has been reflected.
