Note on Gateway Profibus drivers:
Gateway Profibus driver uses 200 words of internal memory (100 words for input and 100 words for output) as per profibus
specification.
This memory is divided into two parts, Input Area and Outptut Area. The first word of Input area is I000 and the first word of
Output area is O000. Pofibus master writes data in Output Area and reads the data from Input Area. With Gateway project
it is possible for serial devices to read the data from Output Area and also they can write the data in Input Area.
This memory is shared memory for Profibus master devices and Gateway firmware system as shown bellow.

sumes this driver as a master driver as it is master to 200 words internal memory.
