How do I change node IDs?



Curtis CAN devices have parameters that store the devices’ Node IDs. In a CIT project, each device also has its Node ID stored as a project property. To change Node IDs, you use the Programmer application to change the devices’ Node ID parameters. After you’ve changed the parameters, you then change the Node IDs stored as project properties.

Important:  Do not change the project properties before changing the parameters.

  1. Click or select Communication » Connect to connect to the CAN bus.

  2. Perform one of the following steps:
    • To change one device's Node ID parameter, select its device node.
    • To change multiple devices' Node ID parameters, you'll probably prefer to select the project's system node. When you select the system node, Programmer will display menus for all of the project's devices.
  3. Click the Programmer button.

  4. In Programmer, find the parameter that specifies the device's node ID.

    Note: The parameter name depends upon the device.

  5. Specify the new node ID.


  6. If the device's manual indicates the parameter requires restarting the device, cycle the keyswitch.

  7. If you need to change node IDs for other devices, repeat steps 3–5.

  8. Once you have finished changing Node ID parameters, close Programmer.

  9. Go to Launchpad.

  10. Click or select Communication » Disconnect to disconnect from the CAN bus.

  11. Select Project » Project Explorer.

  12. Select the device node.

  13. Click Edit Device.

  14. From the Node dropdown, select the new node ID.

  15. Click OK.

  16. If you need to change node IDs for other devices, repeat steps 10-13.

  17. Save the project so that the Node IDs specified as project properties persist.
    Note: Saving applies only to the Node IDs stored as project properties. The parameter values are stored on the devices, not in the project.
