Creating the first application
To check the application press the "Apply" button.
If there is any problem with the application an error message is displayed in the message window.
See section "Info and Error Messages" for a detailed list of all error messages. Fix the problem and press "Apply" again
until no further errors are reported. For this simple application about 4% of the program memory is used. Save the
project now. To complete the application some more logic is needed to realise the delay function. The complete appli-
cation is shown in the next diagram:
The simple logic made of the TOF and FTrig blocks immediately sets the output DO3 following a start pulse at digital
input DI4. After 10 seconds DO3 is switched off again.
The FTrig block detects the falling edge and sets its output to logical 1 for one cycle.
This triggers the DOL start input.
The DOL starter block contains all the logic for the starter function such as checkback supervision etc.
