micapp Posted August 13 Report Share Posted August 13 I have 2 USP-156-X10 with CPU attached. Sometimes the HMI does not respond to touch. If I remove power and reconnect, it is working OK. Is there a reason for this? Is there any shortcut to restart onlly HMI? The PLC cannot be restarted due to application. Quote Link to comment Share on other sites More sharing options...
