That depends upon how your LabVIEW program is written. Some of mine run in loops: Check the inputs / do something / wait 250ms / repeat I can easily put a counter in that: 4 loops/sec * 60 sec/minute * 5 minutes. Reset the counter if a change (input) occurs. Run lock/login if counter hits the 5 minute limit.
Is there room for that in your program? [EMAIL PROTECTED]
