Switched Input Set
At execution time, any given input to a Process will receive data from a single source.
This constraint can easily be met by connecting only a single Process Output Port, External Input or Store access to a given Process Input Port.
But sometimes, the source of input may depend on conditional logic. Consider this example:
The decision in the process at the upper left will cause one of two downstream processes to execute guaranteeing that only one input flows into the selected floor Process Input Port. But we show all possible sources as connections on the data flow diagram forming a Switched Input Set. This set provides content compatible with whatever content is defined on the Process Input Port and, therefore, all inputs in the set must have the same type of content.
Thus a combination of such mutually exclusive inputs, which must all be Process Output Sources since those are the only sources triggered by conditional logic, constitutes yet another possible Process Input Source as established in R52.
