Field Descriptions
Analog Input Data Specifies the value of the analog input data from the module. Specific
format is controlled by Module Data Format Control parameter.
Overrange Alarm Alarm signal for input overrange. This signal is always active.
Range: 0 = normal, 1 = input overrange
Underrange Alarm Alarm signal for input underrange. This signal is always active.
Range: 0 = normal, 1 = input underrange
Remote Fault Alarm Alarm from remote transmitter, indicating transmitter difficulties,
sensor difficulties, or loop to the sensor is open. If not using a remote
transmitter, this alarm can be used as a high-high or low-low alarm.
Depending on Data Format, these current values may be indicated by
percent, mA, or integer values.
Range: 0 = normal, 1 = fault detected
Local Fault Alarm Alarm indicating the loop to the transmitter, or, if there is no transmitter,
the loop is open or shorted. When active, this alarm triggers at 2 mA
and 22 mA for open and short respectively. Depending on Data Format,
these current values may be indicated by percent, mA, or integer
values.
Range: 0 = normal, 1 = fault detected
