Communicate With The Module - Allen-Bradley C Series Installation Instructions Manual

Communicate with the Module

POINT I/O modules send (produce) and receive (consume) I/O data (messages). You
map this data onto the processor's memory.
These modules produce 6 bytes of input data (scanner Rx) and fault status data. These
modules do not consume I/O data (scanner Tx).

Where: OR = Overrange; 0 = No error, 1 = Fault
UR = Underrange; 0 = No error, 1 = Fault
HHA = High/High Alarm; 0 = No error, 1 = Fault
LLA = Low/Low Alarm; 0 = No error, 1 = Fault
HA = High Alarm; 0 = No error, 1 = Fault
LA = Low Alarm; 0 = No error, 1 = Fault
CM = Calibration Mode; 0 = Normal, 1 = Calibration mode
CF = Channel Fault Status; 0 = No error, 1 = Fault
