Fields:

RLADC (index)

Attribute(s):  

Brief:  "Red Limit ADC Number"

Instance(s):  adc

ACD number that exceeded its red limit.

RLCNT (index)

Attribute(s):  

Brief:  "Red Limit ADC Counts"

Instance(s):  cnt

This field is used to report the raw ADC count value that exceeded the specified red limit.

RLDEV (index)

Attribute(s):  LRLIMDEVICE

Brief:  "Red Limit Device Opcode"

Instance(s):  dev

Opcode specifying the device that exceeded a red limit.

RLLIM (index)

Attribute(s):  

Brief:  "Red Limit Threshold"

Instance(s):  lim

This field reports the limit threshold that was used to evaluate the exceeded ADC value.
