Conventional Formats
The configuration tool of PROFIBUS-DP master sets the input and output data length of
PROFIBUS-DP Option from Extended Data 1 (32 bytes), Extended Data 2 (12 bytes), and
Basic Data (6 bytes).
Conventional formats have two message types: High-speed I/O Data and MEMOBUS/
Modbus message.
Set parameter F6-32 to “1” to use conventional formats.
■ High-Speed I/O Data
High-speed I/O data is directly transferred to or from the drive and can control the drive. For
example, when the drive is set for PROFIBUS-DP communications, the drive Run/Stop and
Frequency Reference commands are typically transferred to the drive within 2 ms after
being received by the option.
■ MEMOBUS/Modbus Message
MEMOBUS/Modbus message data is transferred to the drive using MEMOBUS/Modbus
messages. All drive parameters and data can be accessed through MEMOBUS/Modbus.
Because the data in this message type is transferred to the drive after the PROFIBUS-DP
Option receives and edits it, more time is required to return the data to the master. The
master must synchronize the timing of sending and receiving the data by handshaking.

The following memory maps show the I/O data bytes.
