Chapter 2 Configure the Interface
42
For example, if you want to use 0:321 - [DL From Net 01] to write to
Parameter 3 of an optional encoder card plugged into drive Port 5. By using
the formula, the value for 0:321- [DL From Net 01] would be (10000 * 5) +
(3) = 50003.
Follow these steps to enable datalinks to write data.
1. Set the values of only the required number of contiguous controller-to-
drive datalinks that write data to the drive and are included in the
network I/O connection.
2. Reset the drive by cycling power to the drive or by using the Reset
Device function of the HIM located in the DIAGNOSTIC folder for
the drive.
3. Since the logic command and reference are always used in the interface,
configure the parameters in the drive to accept the logic command and
reference from the interface.
When using the controller for speed reference via the interface, set two
fields in drive 10:1800 - [VRef A Sel].
a. Set the Port field for the drive (for example, 0 - PowerFlex 755T).
b. Set the Parameter field to point to the parameter containing the
reference value received from the parameter containing the reference
value that is received from the embedded EtherNet/IP interface
0:211 -[Emb Enet Ref ].
Also, verify that the mask parameters in the drive, (for example,
0:41 - [Logic Mask]) are configured to receive the desired logic
command from the interface. See the drive documentation for
details.
The interface is ready to receive input data and transfer control data
from the controller.
Next, configure the controller to recognize and transmit I/O to the interface.
See Chapter 3, Configuring the drive in a Logix System.
Enable Datalinks to Read Data
The controller input image (drive-to-controller inputs) always contains the
logic status and feedback fields. It can also have 0...16 additional 32-bit
parameters (datalinks). They are configured using 0:340 - [DL To Net 01] ...
355 - [DL To Net 16]. The input connection size in the controller determines
the number of datalinks that are actively used. See the respective controller
example sections in Chapter 3
