4.2.7 Assembly Object
The 1734sc-OE2CIH module will have one configuration assembly, two input
assemblies, and one output assembly. Multiple instances of input assemblies allow the
user to optimize system performance by limiting the produced data to that which is
needed. Input assembly options allow the user to select status only for maximum
throughput status + HART data for both channels. The AOP used for initial release will
support only the Status + All Hart Channels Instance #103.
