4.1.6 Create The LD - "LD1" Program
ISaGRAF will run every program one time in each PLC scan cycle. Programs in the “begin” area will run
first, then the “Sequential” area, and last the “End” area. An ISaGRAF cycle run in the way as the below
scheme.
Click on the "Create New Program" icon and the "New Program" window will appear. Enter the "Name"
as "LD1", next, click on the "Language" scroll button and select "Quick LD: Ladder Diagram", and make
sure the "Style" is set to "Begin: Main Program". You can add any desired text to the "Comment" section
for the LD program, but it isn’t required.
Now we have one program inside this project. Please double click on the “LD1” to get into it.
