Wire the Analog Input Modules
Following are wiring instructions for the analog input modules.
Make sure all connectors and caps are securely tightened to
properly seal the connections against leaks and maintain IP67
requirements.

ATTENTION
(view into connector)
Pin 1 - 24VDC
Pin 2 - Input 0 (M12-A)
Input 1 (M12-B)
Pin 3 - Common
Pin 4 - Common
Pin 5 - No Connect
PSSNACM12A and PSSNAVM12A
IMPORTANT
Analog modules have ear th grounded metal rings.
This should be considered when choosing shielded cables and
grounding techniques.
Communicate With Your Module
I/O messages are sent to (consumed) and received from (produced)
the I/O modules. These messages are mapped into the processor’s
memory. These I/O analog input modules produce 6 bytes of input
data (scanner Rx) and fault status data. They do not consume I/O
data (scanner Tx).

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