Status).
If the Alarm Latch bit is set in the configuration, the Channel Status bits persists
after the alarm condition is cleared. To clear the status bit in this condition, it is
necessary to use the Unlatch Alarm bits in the Output Words (see
Output
Instance below).
NOTE
When configuring this for a Generic Module in RSLogix, it is necessary to
add 4 bytes.
The data below will begin at the third word.

Channel Status Bits
•
CF = Channel Fault status; 0 = no error; 1 = any fault (LCA, HCA, OC)
•
CM = Calibration Mode; 0 = no calibration taking place; 1 = calibration
in process
•
LCA = Low Clamp Alarm; 0 = no alarm; 1 = Low alarm equal to or less
than Low Limit user value.
•
HCA = High Clamp Alarm; 0 = no alarm; 1 = High alarm equal to or
greater than High Limit user value.
•
OC = Open Circuit; 0 = no error; 1 = open circuit
•
HF = Hard Fault; 0 = no fault; 1 = fault
Module Status
•
0 = Module OK
•
1 = Watchdog Fault
•
2 = unused
•
3 = Bad or No Configuration
NOTE
The above status codes are in priority order where multiple conditions
may exist.
