These two data blocks (Input Data and Output Data) consist of a data structure
that provides for the movement of:
 Input Data image from PROFIBUS slave devices
 Output Data image for writing to PROFIBUS slave devices
 PTQ Module Configuration and Status (from PTQ to Quantum)
 PROFIBUS Messaging Mailbox commands (from Quantum to PTQ)
 PROFIBUS Messaging Mailbox responses (from PTQ to Quantum)
