Thank you so much for pointing me in the right direction.
so in my case the name of my CP5613/14 profibus card is 127
example 1;
inb3=127,0,x3 ; inb6 means $IN[25..48]
example 2;
inb6=127,0,x3 ; inb6 means $IN[41..64]
but not at the same time otherwise correlation.
inbX --> input bytes
inbX --> start bytes
127,0,x3 --> the name of the IO carte (in my case CP5613/14)
127,0,x3 --> start bytes PLC
127,0,x3 --> start bytes robot
thanks for your help and your attention
