Yaskawa V7 PROFIBUS-DP - Manual (Page 31)

Network Communications 3-3
16 Word Input/Output Message
The V7 PROFIBUS-DP Option can be configured as one of three possible I/O configurations; 16 word input/output message, 6 word
input/output message and 3 word I/Os, combined input/output, messages. The 16 word input/output message structure is described in this
section.
The 16 word input and output messages are divided into two areas. The first 16 bytes of each message is fixed. This is the most frequently
used data and is referred to as the fast I/O data. The remaining 16 bytes of each message are used for reading from and writing to all other
drive parameters and is referred to as parameter data. All command, monitor, and parameter data in the drive is accessible via the
Parameter Access portion of the message.
