Hi folks! I'm writing a program in GX IEC Developer for my Mitsu FX3U-16M. My program is built up by both LD and ST. All my LD programming, and simple IF- and CASE-executions in ST are working perfectly. The only thing that is not working is loops, I've tried WHILE, FOR and REPEAT. All of them are recognized in GX IEC Developer, when pressing the 'build'-button I have no errors or warnings. But after I've uploaded them to the PLC, and I'm testing the program, the error-lamp on the PLC is lit, and nothing works. So, are there some settings that has to be done in order to make loops work? Thx, Kjetil
