Thanks to the debug mode (see “Operation and Programming”, Chapter 7), the PLC remains
in PLC Stop after booting of the control system. All start-up modes set via softkey only come
into effect when the control system is booted the next time.
The “Run” mode activates the cyclic operation.
The following actions are triggered in the “Stop” mode:
S All hardware outputs are disabled.
S Profibus DP is inactive.
S No cyclic operation (the active user program is not executed).
S The process image is no longer refreshed (it is frozen).
S EMERGENCY STOP active.
Only in the “Stop” mode can the user load a corrected or new project into the control system.
The user program only becomes effective when the control system is booted the next time
or if the “Run” mode is selected.
