How to read HART signal parameter using flex io 1794 IE8H in rslogix 5000?

Ran into this exact problem yesterday. Enabling the "HARTRebuild" allowed for HART communications to work properly after a power cycle to the Flex IO rack.
 
Hi, Can anyone share a sample program how to read additional hart values using 1794-FLEX8H card ?

The one in Rockwell Manual is quite confusing.
