Fast I/O Input Data
The fast I/O input data area is used to transfer parameter data directly from the drive via a dual port RAM interface. The following table
details the functions of the fast I/O input data (Bytes 0 to 3) For detailed explanation of the terminal and multi-function inputs and outputs,
refer to the appropriate drive technical manual.

Parameter Access Area
This area is used to read and write parameter data from and to the drive. The PROFIBUS-DP Master completes the Parameter Access
command (output) message and waits for and then processes the data returned in the response (input) message. These messages may
contain 1 - 4 words of data. The handshaking byte is used to synchronize the communications between the PROFIBUS-DP Master and the
drive. This is necessary due to the additional time required for the drive to process the message.
