Refining the Project SECTION 2 Basic Tutorial 2. In the development environment, select the Green light and then open the Animation Editor dialog. 3. Once again, open the Colour Change (Digital) dialog box. The two colours are shown at the bottom of the dialog box. If necessary, select the colour and change its tone by using the Colour Palette dialog. 4. Select the Red light and animate this in the same manner as for the Green light. Remember that with the traffic signal, the red light needs to be 'ON', that is, bright-red when 'GO' is false (State 0), and dark-red or grey when 'GO' is true (State 1), indicating the bulb is not illuminated. Try runtime once again.
From the toolbar, click the Run button and try out the new tutor application; this time both lights should change colour as the button is selected. If both lights go on and off together then check, and possibly, change the colour definitions as described above. Otherwise the traffic signal should be working as expected - changing from red to green as the button is pressed. On alternate selections, the signal should change back from green to red. Admittedly, this application is very simple, but it demonstrates some key points for all your applications: • The difference between the Development and Runtime applications.
• The system is wholly controlled by data in the points, either in memory or a PLC • Controls (like the Toggle button) can set the data • Graphical controls use Animations to control how the data is displayed This concludes the Basic Tutorial. 19
