11 If ALE configuration bit is not set, the error bit is automatically cleared (0) at the same time that the
condition is cleared.
If ALE configuration bit is set, this alarm will remain set (1) until the condition clears and the end user
sets the appropriate unlatch bit on the Unlatch Alarm Bits (AO_04).
The Low or High Range/Limit value is noted on the User Scaling Table.

Bit definitions for Output Channel Status are provided in the following table:
Description
Under Range <Channel>
When set to 1, indicates the channel output value set by the end user on
the Output Ch<x> (AO_03:00) is less than or equal to the defined Under
Range Alarm value. The Under Range value is determined by the Low
Clamp & Alarm Configuration bit settings (Low Range/Limit/User-
defined bit and its Low Clamp value based on the Data Format and
Range Type selections)
Over Range <Channel>
When set to 1, indicates the channel output value set by the user on the
Output Ch<x> (AO_03:00) is greater than or equal to the defined Over
Range Alarm value. The Over Range value is determined by the High
Clamp & Alarm Configuration bit settings (High Range/Limit/User-
defined bit and its High Clamp value based on the Data Format and
Range Type selections )
Load Error <Channel>
If the channel is set to voltage mode, this bit indicates a short circuit.
If the channel is set to current mode, open circuit is indicated.
DAC Communication Failure <Channel>
When set to 1, indicates there is a channel communication failure over
the module DAC. This is a hardware fault.
Output Driver Over Temperature <Channel>
When set to 1, indicates the channel output driver is overheating. This is
a hardware fault.
Bits marked as Not Used are set to 0.
For even channels, bits 7:5 in the word are unused.
For odd channels, bits 15:13 in the word are unused.
Input Channel Status (AI_04:03)
Each word holds input status bits for two channels. The high byte is for odd
channel and the low byte is for even channel.
