Setting the I/O
Configuration The I/O configuration determines the data that is sent to and from the drive.
Logic Command/Status, Reference/Feedback, and Datalinks may be
enabled or disabled. A “1” enables the I/O. A “0” disables the I/O.
1. Set the bits in Parameter 12 - [DPI I/O Cfg].
Figure 3.3 Example DPI I/O Cfg LCD HIM Screen
Bit 0 is the right-most bit. In Figure 3.3 , it is highlighted and equals “1.”
2. If Logic Command/Reference is enabled, configure the parameters in
the drive to accept the Logic Command and Reference from the adapter.
For example, set Parameter 90 - [Speed Ref A Sel] in a PowerFlex 70 or
700 drive to “22” (DPI Port 5) so that the drive uses the Reference from
the adapter. Also, verify that the mask parameters (for example,
Parameter 276 - [Logic Mask]) in the drive are configured to receive the
desired logic from the adapter. Refer to the documentation for your
drive for details.
3. If you enabled one or more Datalinks, configure parameters in the drive
to determine the source and destination of data in the Datalink(s). For
example, configure the Datalinks in PowerFlex 70 and 700 drives by
setting Parameters 300 - [Data In A1] through 317 - [Data Out D2].
Also, ensure that the Modbus/TCP adapter is the only adapter using the
enabled Datalink(s).
4. Reset the adapter (see Resetting the Adapter on page 3-9 ).
The adapter is ready to receive I/O.
