Fault
ConnectionFaulted
(1)
The owner-controller loses its connection to the module.
Chxx.Fault The channel data quality is bad.
CJChxx.Fault The cold junction data quality is bad.
Chxx.OpenWire The following conditions:
• The channel uses a Voltage input type in any input range and the input signal value reaches full scale.
• The channel uses a Current input type in only the 4…20 mA input range and the input signal goes below 100
μA. The input signal at the channel is below 100 μA.
• When the channel uses RTD or Thermocouple input type and a wire is disconnected from the channel.
CJChxx.OpenWire When a wire is disconnected from the cold junction.
Chxx.Underrange The channel data is beneath the absolute minimum for this channel.
CJChxx.Underrange The cold junction at the channel is beneath the absolute minimum for this channel.
Chxx.Overrange The channel data is above the absolute maximum for this channel.
CJChxx.Overrange The cold junction at the channel is above the absolute maximum for this channel.
Status
RunMode
(1)
The module is in Run Mode.
DiagnosticActive Indicates if any diagnostics are active or if the prognostics threshold is reached.
DiagnosticSequenceCount The count increments a diagnostic.
Chxx.Uncertain The channel data can be imperfect but it is not known to what degree of inaccuracy.
CJChxx.Uncertain The cold junction data can be inaccurate but it is not known to what degree of inaccuracy.
Chxx.OverTemperature The module is operating at a higher temperature than its rated operating limits.
CJChxx.Temperature Current temperature of the cold junction.
Chxx.FieldPowerOff Field power is not present on the channel.
CJChxx.FieldPowerOff Field power is not present at the cold junction.
Chxx.NotANumber The most recently received data value was not a number.
Chxx.LLAlarm The following conditions exist:
• The I.Chxx.Data tag value is less than the C.Chxx.LLAlarmLimit tag value or the alarm is latched.
• The O.Chxx.LLAlarmEn tag is set.
• Alarms are enabled for the channel.
Chxx.LAlarm The following conditions exist:
• The I.Chxx.Data tag value is less than the C.Chxx.LAlarmLimit tag value or the alarm is latched.
• The O.Chxx.LAlarmEn tag is set.
• Alarms are enabled for the channel.
Chxx.HAlarm The following conditions exist:
• The I.Chxx.Data tag value is greater than the C.Chxx.HAlarmLimit tag value or the alarm is latched.
• The O.Chxx.HAlarmEn tag is set.
• Alarms are enabled for the channel.
Chxx.HHAlarm The following conditions exist:
• The I.Chxx.Data tag value is greater than the C.Chxx.HHAlarmLimit tag value or the alarm is latched.
• The O.Chxx.HHAlarmEn tag is set.
• Alarms are enabled for the channel.
Chxx.RateAlarm The following conditions exist:
• The absolute change between consecutive channel samples exceeds the C.Chxx.RateAlarmLimit tag value or the
alarm is latched.
• The O.Chxx.RateAlarmEn tag is set.
• Alarms are enabled for the channel.
Chxx.Data The channel data in scaled Engineering Units.
RollingTimestamp
(1)
A continuously running, 15-bit timer that counts in milliseconds and is not related to the CST.
Whenever a module scans its channels, it records the value of RollingTimestamp then. The controller program uses
the last two rolling timestamp values to calculate the amount of time between the samples.
(1) This tag provides module-wide data and affects all channels simultaneously.
