Bit Definitions for Input Channel Status are provided in the following table:
Description
Under Range <Channel>
When set to 1, indicates the measured value is less than or equal to the
defined Under Range value based on the Data Format and Range Type
selections.
Over Range <Channel>
When set to 1, indicates the measured value is greater than or equal to the
defined Over Range value based on the Data Format and Range Type
selections.
Open Circuit <Channel>
When set to 1, indicates the connection on the remote terminal block is
open.
ADC Communication Failure or PGA Connection Failure <Channel>
When set to 1, indicates there is a channel ADC communication failure or
PGA connection error. This is a hardware fault.
Bits marked as Not Used are set to 0.
For even channels, bits 7:4 in the word are unused.
For odd channels, bits 15:12 in the word are unused.
Output Data Ch<x> (AI_08:05)
Each word reflects the current channel output value in the corresponding
engineering unit based on the user configuration. It is not necessarily identical to
the value set on the Output Ch<x> (AO_03:00). It depends on the operating
mode (Run/Program/Fault).
Input Data Ch<x> (AI_12:09)
Each word reflects the measured channel input value in corresponding
engineering unit based on the user configuration.
Firmware Revision (AI_13)
The lower byte of the word indicates the minor revision of the module firmware.
The upper byte of the word indicates the major revision.
