Posted 2 Jun 2017 Create a special function switch button on your opening page. Choose System Alarm Display. When you have this error press the button and see what the error is. Share this post Link to post Share on other sites

Posted 9 Jun 2017 (edited) First boot your modbus Device and then the HMI. Looks like the HMI is faster at booting up. Edited 9 Jun 2017 by Gambit Share this post Link to post Share on other sites
