In the case of the SmartWire-Darwin slave considered here
the following detailed conditions could be determined.
Acyclic diagnostics
As could already be seen in the configuration, the
SmartWire-Darwin gateway with its slaves appears as a
modular DP slave. This also applies to the structure of the
diagnostic data. PROFIBUS-DP defines for modular slaves a
standard access process for diagnostic information. The
diagnostics consist of standard diagnostics header (DP-V0
header), of a likewise standardized module status and of
optionally extended diagnostic messages in the attachment
from one or several slaves that report detailed diagnostics.
The terms used in the standard PROFIBUS are used in the
following. The designation “module” is synonymous with a
SmartWire-Darwin slave.
Value Meaning
0x10 The contact is longer than four seconds in the
middle position.
0x11 There is a short circuit in the contact.
