Differences between the emulator and a physical controller

RSLogix Emulate 5000 simulates most of the behaviors of Logix5000 controllers. There are exceptions, and you should keep those exceptions in mind as you use the emulator. The following table shows the differences between Logix5000 controllers and RSLogix Emulate 5000.

WARNING: Do not depend on the emulator to match your physical controller’s performance or operation. Some instructions are interpreted differently in the emulator than in a physical controller, and the execution times for instructions and program files will be significantly different in an emulated controller than in a physical controller.
