Configuring the PROFIBUS Module 4-3
4.4 Setting the I/O Configuration
The I/O configuration determines the type of data sent to the drive.
Logic Command/Status, Reference/Feedback, and Datalinks may
be enabled or disabled.
Step 1. Set the bits in module parameter 11 (DPI I/O Config) as
shown in figure 4.3. A “1” enables the I/O. A “0” disables
it. Bit 0 is the right-most bit. In figure 4.3, it is highlighted
and equals “1.”
Step 2. If Logic Command/Reference is enabled (default),
configure the parameters in the drive to accept the Logic
Command and Reference from the module. For example,
set Speed Ref A Sel (SP600 drive parameter 90) to
“Network” so that the drive uses the Reference from the
network. Also, verify that Logic Source Sel (drive
parameter 89) is configured to “Network” so that the drive
uses the logic command from the network.
Step 3. If you enabled one or more Datalinks (optional), configure
parameters in the drive to determine the source and
destination of data in the Datalink(s). Also, ensure that the
PROFIBUS module is the only module using the enabled
Datalink(s).
Step 4. Reset the module. Refer to section 4.5.2, Resetting the
Module.
The module is ready to receive I/O from the master (i.e., scanner).
You must now configure the scanner to recognize and transmit I/O
to the module. Refer to chapter 5, Configuring the PROFIBUS
Scanner, for more information.
