Deactivation of the simulation mode

When the simulation button is clicked in simulation mode, the following wizard dialog (Figure 1) is opened.

The description of the command buttons of the Wizard is given in Table 1.

Push-Button Name	Description
Skip	Skips the step (only if it is optional)
Process	Processes one single step and stops afterwards
Process All	Processes all steps. If any step fails, then the processing will be stopped
Cancel	Cancels the further processing of the steps and closes the Wizard-Dialog
Finish	All steps processed successfully and the "Finish" button closes the Wizard-Dialog
Redo	Appears when one step fails. This gives the opportunity to repeat the actual step.

Table 1: Buttons on the Wizard

The switchover to original mode is performed in several steps (see Figure 1 and Table 2). Some of these steps are mandatory and some are optional (that is they can be bypassed with the 'skip' button).

Requirements

Step	Name	Description
1	Set System(s) to 'Config' mode	All participating systems will be set to 'Config' mode. If the local system is one of these systems, the TwinCAT Simulation manager first sends the 'Reconfig' command to this system. If the local system reaches the 'Config' mode, the 'Restart' command is send to all other remote systems at the same time. The Step succeeds if all systems are in 'Config' mode.
2	Process original settings	The current I/O mappings are removed (locally or remotely) from the simulation PLC, axes are switched back to original mode and deactivated devices enabled again The created original profile is not used if it is not activated and until the TwinCAT system has performed a restart. The step is succeeded when no error occurred setting the configurations.
3	Save TwinCAT Configuration(s)	Saves the locallly cached TwinCAT System Manager Configuration files of all participating systems.
4	Activate Configuration(s)	Activate the configurations on the targets. The configurations will remain inactive until a TwinCAT restart is carried out on the target. The command will succeed if the activating processes ran through without errors.
5	Restart the target system(s)	Restarts the TwinCAT target systems with the activate configurations. Like in Step 1, first the (optional) local system will be restarted and as second step all 'remote' ones in parallel. This step is succeeded if all targets are in 'Run' mode.
6	Write the simulation state	Resets the 'dwSimState' Global PLC Variable to '0' for all participating PLCs. This Symbol is the indicator for the PLCs that the system is in "Original" or "Simulation" mode. The step succeeds if the targets are reachable, the Symbol (TcSimManager.lib) is contained in the PLC project and the value could be written with success.

If all steps succeeded the wizard looks like shown in Figure 2.

The wizard can now be closed via the "Finish" button.
