Hi Sougata,

Thanks, I shall be using the PIC18F448 and am already implementing (E)CAN 2B as this PIC supports it, as you say. The customer however would like to have the Profibus at least 'D' as selectable option. His customers can use any one of the two standards and using a subD 9 pin connector for both systems is aceptable.

The idea is to build all units identically and allow the required selection, Profibus or CAN, to be programmed at commisioning. As far as I know at the moment, this ought to be possible.

Have a nice week-end,

Rob
