Urgent Service notes

  • DNC Connect only supports the actual NX versions who are under maintenance from Siemens.
  • For customers who want to update on the Teamcenter 11.3 version or higher: From TC 11.3 and on, a new license verification will be done upon the creation of manufacturing objects like MEProcess, MEOP, MEWorkArea and their sub-types (including custom types). This check will be done on server side per Teamcenter policy and to ensure license verification. It will use two new feature keys: 1) mfg_planning_lite for verifying MEProcess, MEOP and their sub-types 2) mfg_plant_author for verifying MEWorkArea and its sub-types.
    This new license check will be done in addition to other license verification that exists today. If you don’t find them in your Teamcenter 11.3 or higher license key please get in contact with Siemens PLM.
  • The new UI Shop Floor Connect Active DNC drop support of Internet Explorer 11 and older! Please use Mozilla Firefox, Google Chrome or the new Microsoft Edge Browser!
