Posted 27 Feb 2017 Hi I am trying to test my application before transferring it to HMI. But All I see is question marks or Errors. I have checked RSLinx enterprise communication set up and its pointing to right controller. Is there something else I should check? Any help will be appreciated.

Posted 27 Feb 2017 Did you copy the "design? to the "runtime"? Share this post Link to post Share on other sites
Posted 27 Feb 2017 Can you post a couple of screen shots? Share this post Link to post Share on other sites
Posted 27 Feb 2017 Hopefully you realize that the IPs differ from the design and the runtime tabs? Design is pointed at 103.220 and runtime is pointed at 105.220. Share this post Link to post Share on other sites

Posted 27 Feb 2017 Then you need to investigate the PLC code for the items appearing in the list. Usually, it means that the tagname is not in the PLC to access or possibly the wrong tag type or the syntax is incorrect. Share this post Link to post Share on other sites
Posted 27 Feb 2017 Also, make sure you can ping the PLC from the PC where you're trying to test the screen. I've found it's best to use the tag browser when linking an on-screen object to the PLC to make sure the path is right. That only works when your View Studio PC can see the PLC. If your PC can't see the PLC, you won't be able to test the screen with actual values. Share this post Link to post Share on other sites
