Hello, I have searched the forum and the web, but cannot find the answer to my question. I really hope someone here can explain this to me. I made a program in GX Work2 and I get this error on build/compile: No. Result Data Name Class Content Error Code 1 WARNING AI_kaart Program compile The special relay M8023 is reset by the function INT_TO_REAL. F0207 What does this mean? I cannot find anything about warning F0207. The message means nothing to me, I don't know what the problem here is? Apparently there is something about the INT_TO_REAL function that I am using. The CPU Manual for the FX3-CPU (I have FX3U and FX3G) just says M8023 is unavailable. No further explanation. Can anyone shed a light on this for me, please? Thanks!
