  1. Error code: 4140

    Hallo. Recently ive got an error i haven't seen before. Error 4140 im using GX IEC developer  CPU is Q06UDEH I cannot figure out why the error happens.  When show the location to the step where the error occurs it makes no sense. The specific area has only got simple bool operations. When trying to recompile the entire project. The error "moved" to another location in the program. At this step there was a lot of float operations. When monitoring one of the variable value was NAN. I could not find anything about NAN in the manuals. But google stated it could mean not a number, which makes sense when reading the error description. I know it impossible to help me with my specific problem, when i cant really tell where or why the problem happens. But im pretty sure it has to do with me using float operations wrong. Ive tried to do a simple test program just to see if i could provoke the error, but no luck. How can i make a number go out of range, make it unnormal, nonnumeric or even infinite? Maybe someone could give me a simple example how to provoke this error, which might help me on my search in my own program. Thanks. Below is a screen-dump from the manual on this error.
