About this task

If a device is causing communication problems, the Disable command from the Metasys system UI allows you to take the device offline. Once disabled, the device no longer sends or receives data, but remains in the token loop to maintain bus integrity and pass the token to the next device.

This procedure only prevents data related problems and has no effect on addressing or token loop problems.

Note: This command works on specific devices; it is not available on TEC Thermostat Controllers and may not be available on third-party devices.

To disable a device on the bus:

Procedure

  1. On the navigation tree, right-click the device you want to disable and select Commands from the pop-up menu. A dialog box appears for the device.
  2. Select Disable and click Send. The device goes offline and a red X appears in front of the device in the navigation tree.
    The device remains offline until you repeat this procedure and send the Enable command.
