3-4 Configuring the Adapter
3. 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 “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.
4. If you enabled one or more Datalinks, configure parameters in the
drive to determine the source and destination of data in the
Datalink(s). Also, ensure that the ControlNet adapter is the only
adapter using the enabled Datalink(s).
5. Reset the adapter. Refer to the Resetting the Adapter section in this
chapter.
The adapter 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
adapter. Refer to
Chapter 4 , RSNetWorx Configuration for PLC-5C
Applications .
A hierarchy determines the type of device with which the adapter
exchanges data. In a Master-Slave hierarchy, an adapter exchanges data
with a scanner.
To set a Master-Slave hierarchy
1. Enable the desired I/O in Parameter 13 - [DPI I/O Config] . Refer to
( Figure 3.2 ).
2. Set the bits in the Parameter 25 - [M-S Input] . This parameter
determines the data transmitted from the scanner to the drive.
A “1” enables the I/O.
A “0” disables the I/O.
