3.7.4 Customizable Clamp Ranges and Alarms for Output Channels
In addition to using the basic Under/Over Range Alarm feature on monitoring
channel status based on the Low & High Ranges of the configured Data Format
and Range Type selections, for Output Channel control, you can set different
indications other than default ranges such as limits or user-defined clamp values.
Each Output Channel can control the Low and High Clamp options separately.
Low/High Clamp options for Output Channels are listed in the following table:
Index Clamp Option Note
0 At Range Default
1 At Limit
2
At User-defined Clamp value
• If Option 0 is selected, the channel status indication is the same as
previous Under/Over Range Alarm feature. The Channel Under/Over
Range status, the Channel Fault and module fault bits on the Output
Channel Status (AI_02:01) are set if the Output Channel reading is
less/equal or greater/equal to the Low/High Range.
• If Option 1 is selected, the same bits from above are set if the Output
Channel reading is less/equal or greater/equal to the Low/High Limit.
• If Option 2 is selected, the same bits from above are set if the Output
Channel reading is less/equal or greater/equal to the user-defined Clamp
value.

For monitoring Output Channel status, this bit can also be latched as an alarm. See Alarm Latches for
Output Channels.
