A network variable is already used in another binding


When trying to create a binding or a mirrored point in a LonWorks network, the error "A network variable is already used in another binding" is displayed.


  • Workstation
  • LonWorks Network


Sometimes after deleting a variable the bindings can be left behind. This will cause issues in the future when you try to create another binding with the variable or try to mirror that point again.


The old reference can be cleared out of the database by performing a "Repair references" on the original variable.

  1. Right click on the variable that is creating the error and go to Advanced > Repair references.
  2. Now you can create a binding or mirror the variable into the Local node.
