n3me Posted January 8, 2014 Report Share Posted January 8, 2014 Hi, I’ve encountered problem with JZ10-11-UA24, programmed using latest U90 Ladder 6.4.9 and using O/S JZ V1.12 (B00). PLC controls temperature in oil heater – so I know that it keeps running outputs properly, but after random amount of time lets say 1h or so display and keyboard hang. There is no possibility to change screen - display shows mix of proper data with some random chars in random places seems like multiple variables are being overwritten? I was trying to recompile project, making slight changes, deleting variables etc. even exchanging PLCs - nothing helps.

MVP 2021 Joe Tauser Posted January 10, 2014 MVP 2021 Report Share Posted January 10, 2014 Your code may be continuously triggering a display, which would hang it. Can you upload your program? Joe T. Quote Link to comment Share on other sites More sharing options...
n3me Posted January 14, 2014 Author Report Share Posted January 14, 2014 Hi, Thanks for help. Indeed - visualization of SSRs off/on state was an issue. Regards Maciek Quote Link to comment Share on other sites More sharing options...
