Bind Function Blocks with I/O Chapter 3

Offline Operations

Once configured, products containing DeviceLogix functionality can

operate without a network to perform small local control functions.

Rockwell Automation advises that you use standard DeviceNet cabling

in these applications to accommodate the device’s power

requirements and future configuration needs.

When a network is not used, enable the Comm Status Override

Parameter on the Device Parameters Tab. This will override any errors

that are generated because there is no network. If this parameter is

not enabled, the Outputs will not react to the local logic.

Online Operations

You can perform the following functions when you work on line:

• Communicate with devices

•View the status of I/O with online animation

•Change logic

• Change the value of timers and counters

• Enable and disable logic

•Verify logic

•Compare logic

• Upload and download logic

•Force

• Clear latched hardware faults

Go Online

Once you've created your logic and set up your Scanlist or Override

Parameters, you are ready to go online. While the system is online,

you can make changes (for example, to the Timer and Counter

values) and to the program itself.

Perform the following steps to go online in RSNetWorx software:

1. Click the Online icon on the RSNetWorx software toolbar.

2. Once the network browse is completed, double-click the device

that you want to connect to.

The Device Properties dialog is displayed.

3. Click the DeviceLogix tab.

You may be asked to Upload or Download if you haven't

already done so. Click OK.
