peripheral receive the values from the network. You can use the PowerFlex 20-
HIM-A6 or 20-HIM-C6S HIM, or another drive configuration tool such as
Connected Components Workbench, DriveExplorer, or DriveExecutive software
to select the drive or peripheral by port number and the parameter by name. As
an alternate method, the parameter value can be set manually by number using
this formula:
From Net Parameter Value = (10000 * Port Number) + (Destination Parameter Number)
For example, suppose you want to use Parameter 01 - [DL From Net 01] to
write to Parameter 03 of an optional encoder card plugged into drive Port 5.
Using the formula, the value for Parameter 01 - [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 needed to write data to the drive and that are to be
included in the network I/O connection.
2. Reset the adapter by power cycling the drive or by using the HIM’s Reset
Device function located in the drive’s DIAGNOSTIC folder.
3. Since the Logic Command and Reference are always used in the adapter,
configure the parameters in the drive to accept the Logic Command and
Reference from the adapter.
When using the controller for speed reference via the adapter, set two
fields in drive Parameter 545 - [Speed Ref A Sel].
a. Set the Port field for the drive (for example, 0 - PowerFlex 755).
b. Set the Parameter field to point to the drive port in which the
embedded EtherNet/IP adapter is installed (always ‘Port 13 Reference’,
the drive port dedicated to the embedded adapter).
Also, verify that the mask parameters in the drive (for example,
Parameter 324 - [Logic Mask]) are configured to receive the desired
logic from the adapter. See the drive documentation for details.
After the above steps are complete, the adapter is ready to receive input data and
transfer status data to the master (controller). Next, configure the controller to
recognize and transmit I/O to the adapter. See
Chapter 4 , Configuring the I/O.
Enable Datalinks To Read Data
The controller input image (drive-to-controller inputs) can have 0 to 16
additional 32-bit parameters (Datalinks). They are configured using Parameters
17 - [DL To Net 01]
through 32 - [DL To Net 16]. The number of Datalinks
actively used is controlled by the connection size in the controller. See the
