Debug operations

Since there is no real I/O when emulating a ladder logic project, you can create and edit special program files to simulate the I/O. These files are called debug files . Debug files emulate a piece of your process, simulating inputs to your ladder logic program.

Use Rockwell Software ladder logic editors to create debug files. These editors include:

• RSLogix 500 (for SLC 500 projects)
• RSLogix 5 (for PLC-5 projects)
• WINtelligent LOGIC 5 (for PLC-5 projects)
• A.I. Series Ladder Logistics (for PLC-5 or SLC 500 projects)

Creating debug files

You create debug files with your ladder logic editing application. Rockwell Software applications for editing ladder logic all support creating debug files. For information about creating debug files with your ladder logic editing software, please see the documentation for that software package.

Select debug files for emulation

You can select which debug file you want to use with the emulation session. You can select the debug file when you first open the ladder logic file in RSLogix Emulate, or you can define it later. You can also change the debug file as RSLogix Emulate scans the ladder logic. You can have multiple debug files defined in your ladder logic program, but you can use only one at a time.

To specify which debug file you want to use:

1. Click Settings > Emulation. The software displays a configuration dialog.
2. In the Debug File # field, type the number of the debug file.
3. In the Start Rung field, type the number of the first rung to scan in the debug file.
4. In the End Rung field, type the number of the last rung to scan in the debug file.
5. Click the OK button. The software uses the new settings for the debug file.
