Reset.
bWatchdogReset
The CPU was restarted due the active watchdog
in the last startup.
Table 228: Reset Detailed Diagnostics Group Description
Note:
Brownout Reset: The brownout reset diagnostic is only true when the power supply exceed the minimum limit required
in its technical characteristics, remaining in low-voltage, i.e. without undergoing any interrupt. The CPU will identify the drop
in supply and will indicate the power failure diagnostic. When the voltage is reestablished, the CPU will automatically reset
and will indicate the brownout reset diagnostic.

%QD(n+38)
DINT
Thermometer.
diTemperature
1
Temperature read in the internal sensor of the
CPU.
Table 229: Thermometer Detailed Diagnostics Group Description
Note:
Temperature: In order to see the temperature directly in the memory address, a conversion must be made, since the data
size is DINT and monitoring is done in 4 bytes. Therefore, it’s recommended to use the associated symbolic variable, because
it already provides the final temperature value.
