A higher-level table view displays the station racks and any existing subsystems (PROFINET
IO system, DP Master system).
Status
(display only when the topology display is enabled)
Symbolic status display of the station rack or the subsystem.
For the meaning of these symbols, refer to the following
Name Name of the station rack or subsystem specified in the
configuration.
By clicking on the name, you go to the corresponding Web

Description of the station rack or subsystem entered in the
configuration.
Meaning of the symbols in the "Status" column of the overview page
green Component is OK
gray Disabled PROFIBUS DP slaves or PROFINET IO devices
Condition for support:
• CPU31x PN/DP ≥ V3.2.1 and STEP 7 V5.5 + possibly HSP required for the CPU
• Enabling/disabling the PROFIBUS DP slaves and PROFINET IO devices using SFC12 mode 3/4
• In the "Report system errors" dialog, "Diagnostics support" tab, "Status enabled/disabled" area,
the check mark must be set in the "Query device status enabled/disabled" check box after CPU
startup and optionally in the "Output message at status change" check box.
black Component cannot be accessed/Status cannot be determined
• For example, "Status cannot be determined" is always displayed while the CPU is in STOP
mode, or during startup evaluation of "Report system error" for all the configured I/O modules
and I/O systems after a CPU restart.
• However, this status can also be displayed temporarily during operation if a diagnostic interrupt
burst occurs at all modules.
• It is not possible to determine the status of modules on a subsystem that is connected to a CP.
green Maintenance required
yellow Maintenance requested
red Error - component failed or faulty
- Error in a lower module level
