Pre-conditions to Open a Trigger Window

No need for special compilationGF_ProjectVX code debugging tools operate at run-time. Thus, unlike other programming languages such as C++, the compiler does not need to be told whether or not to support trigger windows: given a PLC code, the compiler’s output is unique, and there is no distinction between debug and release version.Memory availabilityA trigger window takes a segment in the application code sector, having a well-defined length. Obviously, in order to start up a trigger window, it is necessary that a sufficient amount of memory is available, otherwise an error message appears.Incompatibility with graphic trigger windowsA graphic trigger window takes the whole free space of the application code sector. Therefore, once such a debugging tool has been started, it is not possible to add any trigger window, and an error message appears if you attempt to start a new window. Once the graphic trigger window is eventually closed, trigger windows are enabled again.Note that all the trigger windows existing before the starting of a graphic trigger window keep working normally. You are simply not allowed to add new ones.
