When you see online help FC106 of Step 7. You will see: that IN will be MD100 HI_Lim = 100.0 LOW_Lim = 0.0 bipolar = 0 Hope this will guide you. Best regards, Wizard

fvanluchene Posts: 19 Rating: (0)	is it ok if i write it this way // CALL"UNSCALE"FC106 // IN :=MD100 // HI_LIM :=100 //LO_LIM :=0 //BIPOLAR:=false // RET_VAL:=MW2 //OUT :=PQW288 because if i add it from the libary there only stands BG,...,out and if you go over it there stand input word and output word en bool so that isn't right

Then you need to use FC105 Scale (same library) In = PIW272 Hi_lim = 100.0 Lo_lim = 0.0 Bipolar = false out =MD100 fvanluchene and why is hi_lim not 10? because the max is 10V You want to scale from 0 - 100 degr. to 0 - 10 Volt. This will result in a value between 0 and 27648 Best regards, Wizard
