may be you should try this : rung 1 mov #0AFF D20000 this is to enable all channel rung 2 mov #FF0F D20001 this is to setting input and input at 4 20 mA rung 3 mov #F3 D20035 this is to make your MAD42 out put to be 4mA at minimum and 20mA at maximum output and may be you will be asking: why must #0AFF? the answer is: #0AFF = 0000 1010 1111 1111 = output 1 enable, output 2 enable, input 1 enable ,input 1enable, input 2 enable etc, loop1 ratio positive ( it mean "1-0"), loop2 ratio positive too. thank you
