Rockwell Automation 1794-OF8IH FLEX Isolated Input/Output HART Analog Modules - Manual (Page 88)

Publication 1794-UM065B-EN-E - September 2010
76 1794-IF8IH and 1794-OF8IH Configuration
The Module supports six states, common to all Phase 1 EDT compliant
modules, as described below. A single bi-color indicators the module status as
indicated below.
Chapter Summary In this chapter, you learned how to configure your HART module and how to
use the RSLogix software to install and configure your module. The next
chapter describes how to configure your module to automatically collect data
from the HART field device and place it in the module's Input Tag.
