IC200ALG240
Analog Input Module, 16 Bit Voltage/Current, 1500 V AC Isolation, 8 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 via 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 input value is greater than
approximately +12.5 V or 25 mA.
Under-Range
The module reports an Under Range fault if an input value is approximately
0mA on an current channel or –12.5 volts on a voltage channel.
Open Wire
The module reports an Open Wire fault on current inputs if the configuration of
the low end of the range is greater than or equal to approximately 2.0 mA, but
the input 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). Inputs default as specified by the
configuration.
High Limit
The module reports a High Alarm fault if an input 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 input 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.
