I wrote again about this subject but now i explain exactly what i want.
I use STL S7-300. there is a n instruction that convert BCD8421 code to 7SDU and i think that this instruction is SEG from Segment.
I have a counter and two buttons, one for counter up and one for counter down. I also have two 7SDU (Seven Segment Display Unit) as you see in the photo. What i want to do is show the different values of the counter by using those two 7SDUs. (the 14 outputs of the plc (cables) are connected to the 14 inputs of the two 7SDUs)
