CMP Function in GX developer Mitsubishi

[hinddhindsa]

Hi,from A/D module i am importing value using FROM and storing it in D10 register,Next i want to compare it with fix value of 400.But in CMP how can i make this.S1 i keep to D10 and what should be my S2.

 

[Anirban Hazra]

It should be K400. Any Constant value in GX developer is written with a K before it.

 

[hinddhindsa]

so i should keep S2 as k400.i sent you request in facebook.thank you sir.

 

[hinddhindsa]

and suppose if i want to store Value 500 to D15 register then i have to do MOV K500 D15.
right ?

 

[Anirban Hazra]

Yes, that is right.

Hi

Just remember that the cmp uses 3 m bits
1 for less than
1 for equal
1 for greater than

You may want to look at dcmp for double words
