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 HART data for both channels. The AOP used for
initial release will support only the All Hart Channels Instance #103 .
