When using a ControlLogix controller and the Generic Profile, configure the
Datalink parameters now as described in this section.
Parameters 17 - [DL To Net 01]
through 32 - [DL To Net 16] configure which
parameters in the drive, adapter, or any other connected peripheral send the
values to 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:
To Net Parameter Value = (10000 * Port Number) + (Origination Parameter Number)
For example, suppose you want to use Parameter 17 - [DL To Net 01] to read
Parameter 2 of an optional I/O card plugged into drive Port 6. Using the formula,
the value for Parameter 17 - [DL To Net 01] would be (10000 * 6) + (2) = 60002.
Follow these steps to enable Datalinks to read data.
1.
Set the values of only the required number of contiguous drive-to-
controller Datalinks needed to read data from 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.
The adapter is configured to send output data to the master (controller). You
must now configure the controller to recognize and transmit I/O to the adapter.
See
Setting the Adapter to Transmit Peer-to-Peer Data
Peer-to-peer communication can be set up as a simple peer I/O configuration or a
custom peer I/O configuration.
IMPORTANT
Always use the Datalink parameters in consecutive numerical order, starting
with the first parameter. For example, use Parameters 17, 18, 19, 20, and 21 to
configure five Datalinks to read data. Otherwise, the network I/O connection
will be larger than necessary, which needlessly increases controller response
time and memory usage.
TIP
When using a ControlLogix controller and an RSLogix 5000 drive Add-on
Profile, version 16.00 or later, there is no need to configure Datalink
parameters at this time. They will be assigned when configuring the RSLogix
5000 drive Add-on Profile (see
