Posted 15 May 2017 Just after midnight last night a site received EVERY alarm on the HMI but nothing had shutdown. Has anyone ever seen this? Does anyone know why this happened or how to prevent this from happening again? The site is not manned around the clock and the operator received a call out that the whole plant went down. Thanks!

Posted 16 May 2017 No clue here. However I would start by going through ALL logs, iFix and OS paying close attention to those in the alarm time range. Share this post Link to post Share on other sites
