1756-L72K: Processor Module
The 1756-L72K is the Processor Module covered on this page. The attribute that decides whether it fits the existing installation without modification is 2.5 W.
The reason to specify this exact variant is processor module. A processor or controller is selected on memory, scan time and platform compatibility before anything else. processor module sets how much programme fits, how fast the logic executes and which I/O and networks the unit can host — the three things that decide whether an existing application migrates without a rewrite. Confirming 2.5 W against the installed controller family is the check that prevents a processor that boots but cannot run the existing project.
