How to lock a script during execution

[billierios]

Hi,
 
In a project, we use a pushbutton on KNX which triggers a LM4 script that gives instruction to the intercom to give a doorbell sound. But… when they push more than 1 time (like a couples of times directly after eachother), the intercom gets a couple of times the instruction and gets confused.
 
What is the best way to avoid that a running script is executed a second time?
 
Thanks!

Event script has Execution mode: You can select First or Last. Add some os.sleep() on the end to make sure next script is not triggered.
This is implemented in latest fw.
