TAC Xenta Indicates 'Needs Commissioning'

[MikaelKrantz]

Issue

TAC Xenta devices unexpectedly display the status "Needs commissioning."

Product Line

EcoStruxure Building Operation.

Environment

• Building Operation Workstation
• Xenta 401
• Xenta 301/302
• Xenta 281/282/283

Cause

The "Needs commissioning" flag is triggered when there is a change in the device configuration. Common causes include:

• Modification of the Subnet/Node address in the Domain table
• Changes in LonWorks bindings, which may alter:
  • Selector table
  • Address table
  • Alias table
• Upgrades or conversions from TAC Vista to EcoStruxure Building Operation

These changes affect the internal configuration, prompting the system to require re-commissioning of the affected Xenta devices.

Resolution

To resolve the issue:

1. Verify Configuration Changes:

   • Check for any recent modifications in the Domain table, especially Subnet/Node addresses.
   • Review changes in LonWorks bindings that may have impacted the Selector, Address, or Alias tables.

2. Recommission the Device:

   • Use the Building Operation Workstation to recommission the affected Xenta device.
   • Ensure all bindings and addresses are correctly configured.

3. Post-Upgrade Checks:

   • If the issue occurred after a TAC Vista upgrade, verify that all device configurations were correctly migrated.
   • Recommission devices as needed to align with the new system setup.
