Posted 11 May 2017 (edited) I have multiple NA Screens on a control system and they are arbitrarily locking up. The screen becomes distorted and unresponsive. It has happened at least three times on different screens. The only way to resolve the issue is to disconnect then reconnect power. Has anyone seen this issue? Is it a known issue? The controller is an NJ5. Edited 11 May 2017 by justjohn22 Share this post Link to post Share on other sites
Posted 12 May 2017 I have not seen it and use the NA5 frequently. My first guess would be the amount of traffic on the Ethernet, and the number of HMIs making requests of the PLC. Share this post Link to post Share on other sites
