Configuring an I/O Connec tion

Before configuring an I/O connection, you must:

• Configure the WebPak 3000 drive network parameters (refer to chapter 3 in D2-3425-2), set the network
drop number appropriately, and set the control source to network.

• Verify that you have used RSNetWorx for ControlNet to configure the network containing the ControlLogix
chassis and WebPak 3000 drive.

Use the following procedure to configure an I/O connection:
Step 1. After opening the RSLogix 5000 software, verify that you are off-line with the ControlLogix processor.

You can configure an I/O connection when starting a new project or after opening an existing project,
but I/O can only be configured off-line.

Step 2. Define the ControlNet bridge module in your project’s I/O Configuration folder. To do this:

a. Use the right mouse button to click on the I/O Configuration folder.
b. From the pop-up menu, select New Module.
c. From the Select Module Type dialog box, choose the ControlNet bridge of the type (1756-CNB or

1756-CNBR) and series that you are using, then click OK.

d. In the Module Properties dialog box, enter the name of the ControlNet bridge and indicate its

position in the ControlLogix chassis (where 0 indicates the left-most slot). Fill in the Revision and
Electronic Keying fields as appropriate for your application.

e. Click Finish.

Step 3. In the I/O Configuration folder, use the right mouse button to click on the ControlNet bridge, and select

New Module from the pop-up menu. The Select Module Type dialog box displays the various
ControlNet devices known to RSLogix 5000.

Note:

The WebPak 3000 ControlNet Communication Option board simulates a 1771-ACN ControlNet
board. The WebPak 3000 drive appears as a 1771 rack I/O port to ControlNet. By using this
configuration, ControlNet is able to access all the status and control words in the WebPak 3000 drive
and perform scheduled messaging.

Step 4. From the Select Module Type dialog box, select 1771-ACN15 or 1771-ACNR15, depending on

whether or not you are using redundant media, then click OK. The Module Properties dialog box
appears requesting information about the ControlNet module you are using.

Step 5. Enter the information in each of the fields of the Module Properties dialog box as shown in table 3.

Table 3 – Module Properties Configuration Fields

In this field: Enter this information:

Name Give the WebPak 3000 a name that is unique within your project. You will

use this name to direct I/O and explicit messages to the WebPak 3000.

Description Enter a more detailed description of the WebPak 3000 drive’s purpos e,

location, etc., if desired.
Comm Format Select Rack Optimization.
Node Enter the ControlNet address of the WebPak 3000 drive you wish to use.
Input Size Enter the number of words of drive feedback data that you want the

programmable controller to

receive from

the drive (1 to 8). Refer to
section 4.2.3 of the ControlNet Network Communication Option board
manual (D2-3425-2) for information about the type of data that is sent.

Output Size Enter the number of words of drive reference data that you want the

programmable controller to

send to

the drive (1 to 8). See section 4.2.2 in
the ControlNet Network Communication Option board manual (D2-3425-2)
for information about the type of data that is sent.

Electronic Keying Select Disable Keying. Note that the Revision option will become grayed

out.

Step 6. When you have completed entering all the of the information, click Next. The next Module Properties

dialog box in the configuration sequence appears.

Step 7. In the field named Requested Packet Interval (RPI), enter the number of milliseconds desired

between each I/O message between the ControlLogix processor and the WebPak 3000 drive.
Step 8. Click Finish to complete the configuration of the I/O connection using RSLogix 5000 software.
Step 9. Verify that all other I/O in your system is configured.
Step 10. Save the configuration.
Step 11. Download the configuration to the ControlLogix processor.
Step 12. Exit the RSLogix 5000 application (or minimize it).

Scheduling the I/O

Use the following procedure to schedule the I/O:
Step 1. Open RSNetworx for ControlNet application.

Step 2. Verify that you are on-line with the previously configured using the RSNetworx application.
Step 3. Turn on the Enable Edits check box.
Step 4. Save the network. This causes the I/O connection created in the RSLogix 5000 application to be

scheduled in the ControlLogix processor. Select the appropriate save type at the Save Configuration

screen.
After a few seconds, the I/O LED on the ControlLogix processor should stop flashing and remain steadily on

(green). The Control Source Select status (Network) on the WebPak OIM should stop flashing and remain
steadily on.

Troubleshooting Guidelines

If the I/O LED on the ControlLogix processor keeps blinking and/or the Control Source Select status keeps
flashing, it could indicate a number of I/O related problems. Use the following guidelines to isolate the problem:

• If the WebPak OIM Network status remains steadily on, the I/O connection has been made. The flashing

green I/O LED on the ControlLogix processor indicates that another I/O connection did not start correctly.

• A flashing Network status on the WebPak OIM may be the result of a previous error condition on the

network. T ry cycling power on the WebPak 3000 drive and notice if the Network status remains steadily on.

• The I/O may need to be scheduled in the RSNetWorx for ControlNet again. Repeat the scheduling

procedure.

If the above guidelines do not get the I/O connection opened, please contact technical support for the
ControlLogix processor or the WebPak 3000 drive for assistance.

Viewing and Assigning Controller Tag Values

After the I/O connection is open, you can view and assign contoller tag values. Use the following procedure:
Step 1. Open the RSLogix 5000 application.
Step 2. Select the Controller Tags entry.

The name of the controller tag reflects the name assigned to the WebPak 3000 drive during module
configuration. Figures 1 and 2 assume that the name Webpak1 was assigned.

The O subgroup contains one entry for each word of output data you configured and the I subgroup contains
one entry for each word of input data you configured. Refer to sections 4.2.2 and 4.2.3 in the ControlNet
Network Communication Option board instruction manual (D2-3425-2) for descriptions of output and input
words and their associated bits. Sample output and input configurations are shown in figures 1 and 2.
