Where is the main ladder routine program file located in a newly created RSLogix project?

• A. It is the main ladder routine program file
• B. It is the data file
• C. It is the input image table
• D. It is the output image table

Answer: (A)

The main ladder routine is stored as the Main routine inside the program. When you create a new RSLogix project, a default program is created and its Main routine is the ladder logic file that RSLogix executes as the primary routine. Data files hold tag values, while the input image table and output image table contain the I/O state snapshots and mappings—not the ladder logic itself. So the main ladder routine program file sits in the Main routine of the program in the new RSLogix project.
