Analog Output Module, 16 Bit Voltage/Current, 1500 V AC Isolation, 4 Channels
Diagnostics
By default, the module is configured for fault reporting. The module reports
faults as soon as they are detected. Once a fault has been reported, the same
fault is not reported again until the fault has been cleared. Fault reporting can be
disabled through configuration. If disabled, faults are not reported. The module
can detect and report the following faults:
Over-Range
The module reports an Over-Range fault if an output value is greater than
approximately +12.5 volts or 25 mA.
Under-Range
The module reports an Under-Range fault if an output value is approximately
0mA on an current channel or –12.5 V on a voltage channel.
Open Wire
The module reports an Open Wire fault on current outputs if the configuration of
the low end of the range is greater than or equal to approximately 2.0 mA, but
the output is not detecting current.
Loss of Field Power Supply
The module reports a Loss of Field Power fault if field power is not present (also
indicated by the FLD PWR LED). Outputs default as specified by the
configuration.
High Limit
The module reports a High Alarm fault if an output value is greater than or equal
to the value specified by the "Alarm High" configuration parameter.
Low Limit
The module reports a Low Alarm fault if an output value is less than or equal to
the value specified by the "Alarm Low" configuration parameter.
Non-volatile Memory Fault
The module reports this fault only during field recalibration, if a non-volatile
memory fault is detected.
