DIP switch array (S1)
As certification of the FINESSE system is still pending, it was decided to integrate the download
function (possibility to preset the machine data via the FINESSE system) in the software, but to
bar access to this function by a switch until certification of the FINESSE.
For this purpose a 4x switch array was integrated on the board. The state of the switches can be
read via digital input pins of the interface chip (IC1).
