7.5 Profibus error codes

The following error codes occur both in the "result" byte of command-oriented data
exchange (see Chapter 7.2.1 "Profibus commands") and in bits 0–3 of the status
byte in event-oriented data exchange (see Chapter 7.3.1 "Status information in
event-oriented data channel").

2 MDT device error, e.g., memory area defective
3 Error in SLK addressing, e.g., start address and data length exceed limit of an SLK
address segment
Access to nonexistent SLK address segment
4 - Reserved -
5 - Reserved -
6 - Reserved -
7 Attempt to set parameters for prefetch although parameterization was not started.

7.6 Profibus Diagnostic Service

The PDP Diagnostic Service has two sections:
• Normal diagnostics and
• User diagnostics
The SLK provides diagnostic information either when prompted by the PDP master
or when the SLK detects an error in the Profibus function area.
Information in normal diagnostics is Profibus standard. One component is the ID
number, which for the ID 40 system is 0106.
