Independent LogixNG Conditionals executing the same Module


 

I'm looking at creating a Module that may be called by different Conditionals but I want the Module not to act on any subsequent calls during a period of time - First In First Served.
If I'm correct a called Module can have multiple, independent and simultaneous executions (?)
Does the calling Conditional wait for the 'its' module to compete or does it continue?
