SoftLogix Controller
Now we have to check to determine the new controller mode.
_tprintf(_T("now in program mode\n"));
fflush(stdout);
break;
_tprintf(_T("now in run mode\n"));
fflush(stdout);
break;
_tprintf(_T("now in test mode\n"));
fflush(stdout);
break;
_tprintf(_T("now in fault mode\n"));
fflush(stdout);
break;
Windows event tasks are functionality associated with Microsoft's
Windows 2000 and Windows XP operating systems. Applications outside of the
Logix Designer application (Visual Basic, RSView, Custom C applications,
external routines, and so forth) can cause a task within the SoftLogix5800
controller to execute.

Configure a Windows-event Task in the Controller

In the SoftLogix project, we will create a task and configure the trigger as a
Windows event on the controller. Follow these steps.
1. Launch the Logix Designer application.
2. Open the controller1 project we created previously.
3. In the Controller Organizer, right-click Tasks folder and choose
New Task.
