Status | INT | Binary | |
CJUnderRange | This bit is set if the cold junction temperature is below 0° C | ||
CJOverRange | This bit is set if the cold junction temperature is above 70° C | ||
BadTCTypeSelected | This bit is set if an invalid thermocouple type is selected. | ||
PowerUp | This bit is set (1) until configuration data is received by the module. | ||
CriticalError4 | If any critical error bits are set on, return the module to the factory for repair | ||
CriticalError5 | |||
CriticalError6 | |||
Reserved (bit 7) | |||
CalibrationOutOfRange | Set to 1 if a reference signal is out of range during calibration | ||
CalibrationDone | Set to 1 after an initiated calibration cycle is complete | ||
CalibrationBad | Set to 1 if the channel has not had a valid calibration | ||
Reserved (bits 11-15) |
Module-defined Data Type: AB:94_IT8:C:0
Member Name | Type | Default Display Style | Description |
Config1 | SINT | Binary | |
ModuleDataType0 | These bits used in combination as follows: 4 = Degrees C (default) 5 = Degrees F 6 = Bipolar counts scaled between -32768 and 32767 7 = Unipolar counts scaled between 0 and 65535 | ||
ModuleDataType1 | |||
FixedFilterEn | When set to 1, a software digital filter is enabled. This filter settles to 100% of a Full Scale step input in 60 times the selected first notch filter time. | ||
NotchFrequency3 | These bits are used in combination as follows: 0 0 0 10 Hz (default) 0 0 1 25 Hz 0 1 0 50 Hz 0 1 1 60 Hz 1 0 0 100 Hz 1 0 1 250 Hz 1 1 0 500 Hz 1 1 1 1000 Hz | ||
NotchFrequency4 | |||
NotchFrequency5 | |||
GainOffsetCalibration | This bit is set during gain calibration, reset during offset calibration | ||
CalibrationClock | This bit must be set to 1 to prepare for a calibration cycle; then reset to 0 to initiate calibration | ||
