POINT I/O 2 Current and 2 Voltage Input Analog Modules Installation Instructions

Communicate with Your Module

POINT I/O modules send (produce) and receive (consume) I/O data (messages). You map this data onto the processor 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).
Default Data Map
Message size: 6 Bytes
15 14
Input channel 0 – high byte
Input channel 1 – high byte
Produces (scanner Rx)
Status byte for channel 1
OR UR
Consumes (scanner Tx) No consumed data
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

Interpret Status Indicators

The following diagram and table show information on how to interpret the status indicators.

Description
No power is applied to device.
Device is operating normally.
Device needs commissioning due to missing, incomplete, or incorrect configuration.
Recoverable fault is present.
Unrecoverable fault occurred. Self-test failure present (checksum failure, or ram test failure at cycle power). Firmware fatal error present.
Device is in self-test mode.
Device is not online:
• Device has not completed dup_MAC-id test.
• Device is not powered – Check the module status indicator.
Device is online but has no connections in the established state.
Device is online and has connections in the established state.
One or more I/O connections are in timed-out state.
Critical link failure – Failed communication device. The device has detected an error that prevents it from communicating on the network.
Communication faulted device – The device has detected a network access error and is in communication faulted state. Device has received
and accepted an Identity Communication Faulted Request – Long protocol message.
