I have not used Mux until recently, but I am starting to do it. It can save lots of time when used properly ! For example, in the project for multiple displays uploaded by Federico yesterday:
ProbeDisplayed := MUX(currentview,probeAI1,probeAI2, probeAI3,probeAI4,probeAI5);
dp := MUX(currentview,1,1,2,0,1);
um := MUX(currentView,5,5,3,1,5);
/*
case currentview of
0:
ProbeDisplayed := probeAI1;
dp := 1; (* 1 decimal point *)
um := 5; (* °C *)
1:
ProbeDisplayed := probeAI2;
dp := 1; (* 1 decimal point *)
um := 5; (* °C *)
2:
ProbeDisplayed := probeAI3;
dp := 2; (* 2 decimal point *)
um := 3; (* Bar *)
3:
ProbeDisplayed := probeAI4;
dp := 0; (* No decimal point *)
um := 1; (* %Rh *)
4:
ProbeDisplayed := probeAI5;
dp := 1; (* 1 decimal point *)
um := 5; (* °C *)
end_case;
*/
However, in FBD I could not find a way to increase the number of inputs to the block. Is it possible somehow ? Default is 2 inputs.

I see. I am so used to the right click procedure that works for other blocks that I did not notice that. Thank you.
