This message is displayed during V+ initialization (i.e. during the booting process) to indicate that the V+ system is operating in Adept Digital Workcell simulation mode and that the V+ system is waiting for a response from the PC that is running the Adept Digital Workcell software. No response is needed if the connection completes successfully. If the connection does not complete you can enter CTRL+C to cancel waiting for the connection. The V+ system then reports failures of all the robot servos and all the installed licenses are disabled (except those needed to use the Adept ACE user interface). In that case you should either try again to start up the Adept controller (after making sure that the Adept Digital Workcell software is running on the PC) or enter the V+monitor command DISABLE ADW and restart the Adept controller.
