PROFIBUS-DP Option Data and I/O Maps

◆
Conventional Formats
The configuration tool of PROFIBUS-DP master sets the input and output data length of SI-
P3/V 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 = "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.
MEMOBUS/Modbus message
■
MEMOBUS/Modbus message data is transferred to the drive using MEMOBUS/Modbus
messages. All the drive parameters and data can be accessed by this data. Because the data in
this message type is transferred to the drive after the SI-P3/V 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 drive run command and/or the frequency reference change immediately by High-speed
I/O when commanded by MEMOBUS/Modbus messages.
