Configuring the “START“ Button 
 
To start the color mixing plant, we still need the button “START“. 
The button is to blink green when the start enable of the program is activated. 
The button can only be operated when start enable is active. 
 
From the tool window, under Basic Objects, drag a Button into the basic display. 
Under Allgemein (General), at Text AUS, enter “START“. 
Change the background color to white, and select a smaller font size. 
Set position X280Y110 and the size 40 x 20
 
In the function list, select the function “SetzeBit“ at Press (Drücken). 
 
 
 
 
As variable, select  “start_prog“ from DB1. 
We want to generate the function of a button; for that reason, you are now configuring the function 
RuecksetzeBit“ with the variable “start_prog“ when releasing (loslassen) the button.
