If your S5 CPU support floating point operation you have to write (german mnemonics) : L MW100 //load int (KF) value SLD 16 // clean ACCU1-H SVD 16 FDG // convert to real (KG) value T MD120 Hope this helps Best Regards

For ladder there are conversion blocks there you can use the Integer to double Integer then use that value to feed it to the, DoubleInteger to Real here you get the final output
