Cognex supports time-limited security keys for application developers. Development keys have the following features:
- An expiration date up to 10 years in the future
An application session limit of 5 hours
You can stop and restart VisionPro for another 5-hour session at any time.
Use Cogtool, a utility included with your VisionPro installation, to discover how much time remains on your development key.
Enter the following in a command prompt window:
cogtool --print | more
The output shows when the development key expires, accurate to within a five minute range:
There is 1 Cognex Security device installed.
