Name
Data Type
Definition
Valid Values
RunMode
BOOL
Channel’s operating state
0 = Idle
1 = Run
When the value is 0, it means one of the following:
  • Connection is not up.
  • Connection has been opened but the module has not started producing data for the connection.
  • Module is not applying new Output tag data because the controller is in Program Mode.
When the value is 1, it means the following:
  • Connection is up.
  • Module is producing data for the connection.
  • Output tag data is being applied.
ConnectionFaulted
BOOL
Indicates if a connection is running.
The module sets this tag to 0 when connected. If the module is not connected, it changes the tag to 1.
0 = A connection exists between the module and the controller
1 = Connection is timed out or inhibited
DiagnosticActive
BOOL
Indicates if any diagnostics are active or if the prognostics threshold is reached.
0 = No diagnostics are active
1 = One or more diagnostics are active or the prognostics threshold is reached.
DiagnosticSequenceCount
SINT
Increments for each time a distinct diagnostic condition is detected, and when a distinct diagnostic condition transitions from detected to not detected.
-128...+127
The value of 0 is skipped except during module powerup.
Chxx.Fault
BOOL
Indicates that channel data is inaccurate and cannot be trusted for use in the application.
If the tag is set to 1, you must troubleshoot the module to correct the cause of the inaccuracy.
IMPORTANT: Once the condition that causes the tag to change to 1 is removed, the tag automatically resets to 0.
0 = No fault exists
1 = Fault exists
Chxx.Uncertain
BOOL
Indicates that the channel data can be inaccurate but the degree of inaccuracy is not known.
If the tag is set to 1, you must troubleshoot the module to correct the cause of the inaccuracy.
IMPORTANT: Once the condition that causes the tag to change to 1 is removed, the tag automatically resets to 0.
0 = Valid data
1 = Data validity uncertain
Chxx.OpenWire
BOOL
The signal wire is disconnected from the channel or the RTB is removed from the module.
0 = Open wire condition does not exist or open wire detection is disabled
1 = Open wire condition exists, that means the signal wire is disconnected from the channel or the RTB is removed from the module
Chxx.OverTemperature
BOOL
Not applicable for this module.
N/A
Chxx.FieldPowerOff
BOOL
Field power is not present at the channel.
0 = Field power is present
1 = Field power is not present
Chxx.NotANumber
BOOL
Indicates if the last received channel data was not a number.
0 = Last channel data received was a number
1 = Last channel data received was not a number
Chxx.Underrange
BOOL
Indicates the channel data is beneath the underrange threshold for this channel.
For example, when the channel operates in the 4…20 mA input range, the underrange threshold on the channel is <3.0 mA. If the input signal is 0 mA, this tag is set to 1.
0 = Channel data is not beneath the underrange threshold
1 = Channel data is beneath the underrange threshold
Chxx.Overrange
BOOL
Indicates the channel data is above the overrange threshold for this channel.
For example, when the channel operates in the 4…20 mA output range, the overrange threshold on the channel is >23.0 mA. If the input signal is 24 mA, this tag is set to 1.
0 = Channel data is not above the overrange threshold
1 = Channel data is above the overrange threshold
Chxx.LLAlarm
BOOL
Triggered when the input data value is less than the Low Low Alarm value.
If latching is enabled, this alarm remains triggered until unlatched. If latching is not enabled, the alarm clears after the input data value is greater than the Low Low Limit plus the Alarm Deadband.
0 = Alarm is not triggered
1 = Alarm is triggered
Chxx.LAlarm
BOOL
Triggered when the input data value is less than the Low Alarm value.
If latching is enabled, this alarm remains triggered until unlatched. If latching is not enabled, the alarm clears after the input data value is greater than the Low Limit plus the Alarm Deadband.
0 = Alarm is not triggered
1 = Alarm is triggered
Chxx.HAlarm
BOOL
Triggered when the input data value is greater than the High Alarm value.
If latching is enabled, this alarm remains triggered until unlatched. If latching is not enabled, the alarm clears after the input data value is less than the High Limit minus the Alarm Deadband.
0 = Alarm is not triggered
1 = Alarm is triggered
Chxx.HHAlarm
BOOL
Triggered when the input data value is greater than the High High Alarm value.
If latching is enabled, this alarm remains triggered until unlatched. If latching is not enabled, the alarm clears after the input data value is less than the High High Limit minus the Alarm Deadband.
0 = Alarm is not triggered
1 = Alarm is triggered
Chxx.RateAlarm
BOOL
Triggered when the change between consecutive channel samples divided by the period of time between when the samples were taken exceeds the Rate Alarm. If latched, this tag remains set until it is unlatched.
0 = Alarm is not triggered
1 = Alarm is triggered
Chxx.CalFault
BOOL
Indicates the last attempted Calibration for this channel failed or there is no calibration data present.
This tag is cleared, that is, set to 0, when power is cycled to the module or a successful calibration for the range on the channel is performed.
0 = Calibration did not fail
1 = Calibration failed
Chxx.Calibrating
BOOL
Indicates the channel is currently being calibrated.
0 = Channel is not being calibrated
1 = Channel is being calibrated
Chxx.CalGoodLowRef
BOOL
Indicates that a valid Low Reference signal is sampled on this channel in the calibration process.
IMPORTANT: This tag is available only when you use the Data with Calibration connection type in the Device definition dialog. If you use the Data connection type, this tag does not appear in the module tags.
0 = Valid Low Reference signal has not been sampled on this channel
1 = Valid Low Reference signal has been sampled on this channel
Chxx.CalBadLowRef
BOOL
Indicates that an invalid Low Reference signal is sampled on this channel in the calibration process. You must correct this condition to successfully calibrate the module.
If calibration is aborted with an invalid Low Reference signal, the Chxx.CalFault tag is set for this channel until a successful calibration is performed.
IMPORTANT: This tag is available only when you use the Data with Calibration connection type in the Device definition dialog. If you use the Data connection type, this tag does not appear in the module tags.
0 = Invalid Low Reference signal has not been sampled on this channel
1 = Invalid Low Reference signal has been sampled on this channel
Chxx.CalGoodHighRef
BOOL
Indicates that a valid High Reference signal is sampled on this channel in the calibration process.
IMPORTANT: This tag is available only when you use the Data with Calibration connection type in the Device definition dialog. If you use the Data connection type, this tag does not appear in the module tags.
0 = Valid High Reference signal has not been sampled on this channel
1 = Valid High Reference signal has been sampled on this channel
Chxx.CalBadHighRef
BOOL
Indicates that an invalid High Reference signal is sampled on this channel in the calibration process.
You must correct this condition to successfully calibrate the module.
If calibration is aborted with an invalid High Reference signal, the Chxx.CalFault tag is set for this channel until a successful calibration is performed.
IMPORTANT: This tag is available only when you use the Data with Calibration connection type in the Device definition dialog. If you use the Data connection type, this tag does not appear in the module tags.
0 = Invalid High Reference signal has not been sampled on this channel
1 = Invalid High Reference signal has been sampled on this channel
Chxx.CalSuccessful
BOOL
Indicates calibration on this channel is complete and the Calibrating state has been exited.
This tag remains set after valid calibration and until a new calibration process is started or the connection is closed.
IMPORTANT: This tag is available only when you use the Data with Calibration connection type in the Device definition dialog. If you use the Data connection type, this tag does not appear in the module tags.
0 = Calibration was not successful
1 = One of the following:
  • Calibration was successful and calibrating state has been exited.
  • Calibration data is present and applied.
Chxx.Data
REAL
Channel data in scaled Engineering Units.
Any value
Chxx.RollingTimestamp
INT
Continuously-running 15-bit timer that counts in milliseconds.
Whenever an input module scans its channels, it also records the value of RollingTimestamp at that time. The user program uses the last two RollingTimestamp values and calculates the interval between receipt of data.
