The PROFINET interfaces with integrated switch of the SIMATIC devices support the four-
level diagnostics concept in accordance with PROFINET specification Version V2.3 or higher
with the following status:
Table 4- 5 Classification of the diagnostic status
Diagnostic status
Symbol
Severity of the error
Good Green checkmark
Maintenance

Green wrench
Maintenance

Yellow wrench
Bad Red wrench
The aim of the diagnostics concept is the early detection and elimination of potential faults -
before they cause a production outage.
Other status information is defined in addition to the Good (no fault) and Bad (fault) status
information for a PROFINET device.
The maintenance information is generated with the following system alarms:
● Maintenance required (symbolized by a green wrench) and
● Maintenance demanded (symbolized by a yellow wrench)
The times at which the two system alarms are generated can be customized for most wear
parameters.
