Total Input Length, Total Output Length: The sum of Input/Output lengths for
all slaves in the database (in bytes).

not to the input/output directions used in the bus database or the NetTool-PB.

file. This is the string that was written to the database by the
"FB_APPL_END_DATABASE_DOWNLOAD" command.
