n3me Posted January 8, 2014 Report 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. Regards, Maciek
MVP 2023 Joe Tauser Posted January 10, 2014 MVP 2023 Report Posted January 10, 2014 Your code may be continuously triggering a display, which would hang it. Can you upload your program? Joe T.
