Changing modes

To change the mode of a project, select the project from the file selection list box, then click the button for the mode you want to use. (You can also select modes from the Ladder menu.

The modes operate as follows:

• Program (Halt) mode stops program execution.
• Run mode runs the program based on the parameters used when the program was loaded into RSLogix Emulate's memory. Normally, the program runs as if it was in a processor.
• Single-scan mode scans the emulated program once. To use this mode, click the Tst button, then click the Scn button each time you want to scan the program. An alternative to clicking the Scn button is pressing CTRL-SPACEBAR.
• One-rung mode scans the emulated program one rung at a time. To use this mode, click the One button, then click the Scn button each time you want to scan the program. An alternative to clicking the One button is pressing CTRL-SPACEBAR. In the lower right-hand corner of the RSLogix Emulate window is a display showing where you are in the ladder logic file, by program file and rung number (e.g., 2:38 indicates program file 2, rung 38).

If you are online with the emulated project with RSLogix 5, RSLogix 500, PLC-500 A.I. Series, PLC-5 A.I. Series, or WINtelligent LOGIC 5, you can change modes as if you were communicating with a processor in Remote mode. (In WINtelligent LOGIC 5 and A.I. Series software, you cannot change to the Single-scan or One-rung modes; for those modes, you must use RSLogix Emulate's icons or menus.)
