5 bit binary input, 4 bit binary output
Hello
I need to read the status chart and write the control chart. I'm only using 4 input bits. I am wondering if there is a simple function block to do this or do I need to build it from scratch?
I'm using the PM5630-ETH
![]()

Hello
What I usually use are matrices. E.G. let me use a smaller example: imagine you have 2 inputs and 3 outputs. you can create a doble vector variable:
matrix: ARRAY[0..1] OF ARRAY[0..1] OF INT;
So, if your inputs are D1 and D2, and thery are BOOL, first, you convert them to INT. if the INT versions are D1_INT and D2_INT, you can access all elements on matrix using:
OUTPUT := matrix[D1_INT][D2_INT];
obviously, you need to give initial values to the matrix variable according to the desired OUTPUT values for each input combination
Best Regards
