Configuring the Option Module
Using the formula, the value for
Host 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 option module; see
Resetting the Option Module on page 49
.
3.
Since the Logic Command and Reference is always used in the option
module, configure the parameters in the drive to accept the Logic
Command and Reference from the option module. When using the
controller for speed reference via the option module, 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 option
module is installed (for this example, Port 4 Reference).
Also, verify that the mask parameters in the drive (for example,
Parameter 324 - [Logic Mask]) are configured to receive the desired
logic from the option module. See the drive documentation for details.
After the above steps are complete, the option module 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 option module. See
Enabling 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
Host
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 respective controller example sections in
for more information on
setting the connection size.
IMPORTANT
Always use the Datalink parameters in consecutive numerical order, starting
with the first parameter. For example, use Host 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
