Posted 26 Dec 2006 Is there a way I can monitor the status of Efuses? Can I reset them from an HMI? I'm pretty sure you can, just can't find any information on it. Thanks Share this post Link to post Share on other sites
Posted 26 Dec 2006 What's the part number of your device? Are you talking about the 1756-OA8E? Share this post Link to post Share on other sites
Posted 26 Dec 2006 There should be a fuseblown tag, with 1 bit per I/O point. When a blown fuse is detected, the bit is latched. You should be able to reset this bit from your HMI. It may be covered in this manual: http://literature.rockwellautomation.com/i...um058_-en-p.pdf Share this post Link to post Share on other sites
Posted 27 Dec 2006 Just be aware that simply resetting a fuse blown indicator without actually diagnosing the problem is a clear violation of OSHA regulations. Same thing with operators simply resetting breakers. One of the reasons I prefer real fuses...they can't be reset. Share this post Link to post Share on other sites
Posted 27 Dec 2006 Let's say your module was in slot 4 Blow Fuse Indicators - Local:4:I.FuseBlown.0-Local:4:I.FuseBlown.7 Field Power Loss Indicators - Local:4:I.FieldPwrLoss.0-Local:4:I.FieldPwrLoss.7 You use a MSG instruction to reset the fuses. You reset the entire set o module fuses at one time Message Type - CIP Generic Service Type - Reset Electronic Fuse Source Element - Tag type DINT, value 0 Path - Your Module Share this post Link to post Share on other sites
