Tag Definitions Appendix A
Ch0NotANumber BOOL Decimal Ch0Status:5
Ch0Data is not a valid floating point number.
Ch0OpenWire BOOL Decimal Ch0Status:7 Only valid in current mode (example 4…20 mA). 1 indicates no current is flowing,
probably due to open circuit.
Ch1Status SINT Binary Indicates various alarms on the analog signal. Also sets Ch1Fault.
Ch2Status SINT Binary Indicates various alarms on the analog signal. Also sets Ch2Fault.
Ch3Status SINT Binary Indicates various alarms on the analog signal. Also sets Ch3Fault.
Ch4Status SINT Binary Indicates various alarms on the analog signal. Also sets Ch4Fault.
Ch5Status SINT Binary Indicates various alarms on the analog signal. Also sets Ch5Fault.
Ch6Status SINT Binary Indicates various alarms on the analog signal. Also sets Ch6Fault.
Ch7Status SINT Binary Indicates various alarms on the analog signal. Also sets Ch7Fault.
Ch0Data REAL Float Analog value actually output in engineering units. This might be different than output tag Ch0Data if
the value exceeds the LowLimit or HighLimit, has a MaxRampRate applied, is being Held for
initialization, or controller in Fault or Program mode
Ch1Data REAL Float Analog value actually output in engineering units. This might be different than output tag Ch1Data if
the value exceeds the LowLimit or HighLimit, has a MaxRampRate applied, is being Held for
initialization, or controller in Fault or Program mode
Ch2Data REAL Float Analog value actually output in engineering units. This might be different than output tag Ch2Data if
the value exceeds the LowLimit or HighLimit, has a MaxRampRate applied, is being Held for
initialization, or controller in Fault or Program mode
Ch3Data REAL Float Analog value actually output in engineering units. This might be different than output tag Ch3Data if
the value exceeds the LowLimit or HighLimit, has a MaxRampRate applied, is being Held for
initialization, or controller in Fault or Program mode
Ch4Data REAL Float Analog value actually output in engineering units. This might be different than output tag Ch4Data if
the value exceeds the LowLimit or HighLimit, has a MaxRampRate applied, is being Held for
initialization, or controller in Fault or Program mode
Ch5Data REAL Float Analog value actually output in engineering units. This might be different than output tag Ch5Data if
the value exceeds the LowLimit or HighLimit, has a MaxRampRate applied, is being Held for
initialization, or controller in Fault or Program mode
Ch6Data REAL Float Analog value actually output in engineering units. This might be different than output tag Ch6Data if
the value exceeds the LowLimit or HighLimit, has a MaxRampRate applied, is being Held for
initialization, or controller in Fault or Program mode
Ch7Data REAL Float Analog value actually output in engineering units. This might be different than output tag Ch7Data if
the value exceeds the LowLimit or HighLimit, has a MaxRampRate applied, is being Held for
initialization, or controller in Fault or Program mode
CSTTimestamp DINT[2] Decimal 64-bit coordinated system time timestamp in microseconds of the last output update. Timebase
synchronized with other modules in the rack
RollingTimestamp INT Decimal 16 bit timestamp in milliseconds. Timebase local to the 1756-OF8H module.
