Rockwell Automation 1794-OF8IH FLEX Isolated Input/Output HART Analog Modules - Manual (Page 78)

Publication 1794-UM065B-EN-E - September 2010
66 1794-IF8IH and 1794-OF8IH Configuration
Range: 0…15. Refer to the 1794-OF8IH Data Formats table.
If data is sent to the module which is out of range, the value is clipped and
Diagnostic Data is set to "11" data out of range. To view a graphical
representation of this performance, see the example on page 12.
