11.3 Temperature monitoring
SIMATIC Panel PC 677B

11.3 Temperature monitoring
The temperature is recorded by means of three thermocouples. One thermocouple monitors
the processor temperature, another the temperature in the area near the power supply, and
a third the air intake temperature next to the DVI port.
The following fault reactions are triggered if one of the temperature values exceeds the set
temperature threshold:
Response Option
Device and CPU fans accelerate to maximum
speed.
None
SOM or DiagMonitor software is activated None
The temperature error is retained in memory until temperatures have fallen below the
thresholds and are reset by one of the following measures:
● Error acknowledgement in the SOM program (manually by means of the broom icon)
● Restart of the device
11.4 Watchdog (WD)
Function
The watchdog monitors program execution and reports a program crash to the user by
means of various reactions.
The watchdog is idle when the PC is switched on or after a HW-RESET(cold restart), i.e., no
reaction of the WD is triggered.
WD reactions
If the WD is not retriggered within the set time (by the driver or in the SOM program), the
following reactions are triggered:
Response Option
WD acknowledgement None
Trigger a PC reset Selectable
SOM or DiagMonitor software is activated None
