The initial API block (iNbrApi) defines the number of APIs in the configuration.
Each API has an initial module block, that includes information on the API number (iApiNbr) and the number of
modules (or slots) in the API.
Each module starts with a module block, which holds the slot number, the number of submodules (or subslots)
and the module identity number.
Finally each submodule block holds subslot number, submodule identification number, input and output data
lengths.
