GX Works2 / FX3 CPU Program Compile Error - What does it mean?

8 posts in this topic

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!

M8023 is a special relay from the FX2C series which enables floating point operation. This isn't needed in the FX3U. Was the project originally for a FX CPU

I wouldn't worry about it is just a warning probably build in for project converted from FX2N.

Hi, I converted a FX2N project to FX3u, this had 8 real number calculations and produced the same error for each. Didn't matter what i did I could not remove the compile warning, however there was no impact on the operation. Using GX Works2 Ver 1.87R I believe. Edited by Cetronic
