5.5 Monitoring of the device
5.5.1 Monitoring functions
You can monitor the following device functions with the SIMATIC DiagBase or SIMATIC
DiagMonitor software:
Status display and actions
monitoring
• Monitoring of high and low temperature limits and
cable break of the temperature sensors
• For this, temperature sensors record the temperature
at critical points of the device, e.g. at the processor.
• The temperature thresholds are defined for the
individual temperature sensors.
• With SIMATIC IPC DiagBase or SIMATIC IPC
DiagMonitor, actions are triggered when the
temperature thresholds are exceeded.
• Status display "TEMP (Page 31)"
• Closed-loop speed control of the
device fans, the power supply fan
and the fan of the optional graphics
card
• Temperature alarm is output.
• Monitoring of underspeed and failure of a fan as well
as cable break of the tachometer cable
The operation of the fan is monitored at the following
positions:
• Front panel
• Processor
• Optional graphics card
• Power supply (not redundant)
• Status display "FAN (Page 31)"
• Fan alarm is output.
• Monitoring of the system status and message as to
whether a station is still operational.
• If the watchdog is not operated within a configured
monitoring time, a watchdog alarm is output.
• A change to the monitoring time is effective
immediately.
• Status display "WATCHDOG
(Page 31)"
Depending on the setting, the following
actions are initiated:
• Reset on: A hardware reset is carried
out
voltages
• Monitoring of the charge status of the buffer battery
(CMOS)
• When the first warning threshold is reached, the
backup battery will run for at least 1 more month.
• If a critical or error status occurs, an
alarm is output.
• Determination of the status of the drives (HDD and
SSD) with SMART functionality (SMART: Self-
Monitoring, Analysis and Reporting Technology) also
in RAID systems (RAID state)
• The status of an inactive hot swap drive is not
displayed.
• Status display "HDDx ALARM
(Page 31)"
• SMART status of the hard drives
• The following statuses, for example,
are displayed in a RAID system:
"Normal", "OK", "Degraded", error
"Rebuild", rebuilding
