Dwell Time
—the length of time that the Switch States variable has spent in the current state.
Device
Temperature
—indicates the temperature of the electronics.
Voltage
—indicates the power module voltage.
Quality variables below
Temperature
and
Voltage
indicate the overall process data quality of
the item. Values are Good,
Degraded, Bad, or Manual/Fixed.
Note
Power module warnings generally only apply to the standard and extended life power modules.
An external power sourced 4320 will provide the supply voltage levels from the output of the external power assembly, not the
voltage of the supply source.
Warning Voltage
—the threshold for the power module low-voltage warning.
Critical Voltage
—the threshold for the power module critical-voltage warning. Device configuration changes are
prohibited below this voltage.
