Flow Control Setup
This dialog can be opened by the option measurement|properties or by the context menu properties (right click on background of the signal graph.)

Timing:
Sleep times are necessary for other application may work parallel to this signal graph. If no sleep time is specified you may deadlock your computer.
Sleep time after loop: After all proccessing modules have processed their data, and before the source modules are called again, the signal graph waits this specified time.
Scheduled loop time:
Minimum time a loop should last (inclusive all sleep times).
Sleep time after module precessing:
Time the signal graph waits after module processing. 
All x Modules:
The waiting is done every x-th modules.
Signalgraph parameter
Autostart after loading:
ICONNECT starts this signal graph automatically, when it is opened
Hide signal graph for user group 0!:
Users that have execution rights only cannot see the signal graph.
Hide signal graph for user group 1!:
Users that have edit rights only cannot see the signal graph.
Do not increase base priority:
Use no time critical priorities.
Fix display when loading:
Locks the displays of the signal graph, after loading it.
Priority
Sets the thread priority of the signal graph. A priority very high slows down other signal graphs and applications. A low priority may cause interruptions in the flow of the signal graph and may eventually disturb any time critical measurements.
Log file:
Name: Path and file name of the log file. (For default “Log.txt” is used.) Use the 'Browse' Button to choose a file.
Activate profiler:
This option starts the logging of module processing times. Signalgraph run time, module calls and lots more.
The button ‘Error suppression’ opens a dialog that lets ICONNECT ignore some errors. If one of these errors occur ICONNECT writes it to the specified log file and then restarts the signal graph.
