Instruction difference FX3G vs FX3U

[Bryll 31]

Was a bit disappointed yesterday when I started to write the code for a FX3G CPU. Tried to make a tiny system a bit cheaper for one of my best customers, so I bought a FX3G instead of the FX3U I use as a standard in his systems. I noticed very soon that some of the instructions used in a structured text formula wasn't implemented in the 3G CPU. So instead of a nice short formula to calculate the evaporation and condensation temperature of NH3 from its pressure, was I forced to write a big memory consuming "look-up" table. Is there a list of what instructions FX3G doesn't have, but FX3U does have ? Searched for a while yesterday, but couldn't find any clear answers. Guess I have to be surprised again when writing the code

A simple table, you try to find, is absent, but the information can be got in the JY997D16601N document. Using it you can easy build own.

Got surprised again I'm reading information from a frequency drive and store the status word in D200, that's not a problem. But when trying to pick out the different status bits, like the running feedback status in D200.2 as a Boolean bit. The compiler refuses to accept it. There's no problem to move D200 to a range of M positions, but it seems to me that the FX3G was not the best choice of CPU. Or could this be changed by some setting for the compiler ? Let's see what next surprise will be

This can not be changed by compiler settings.
