To make an individual (not automatic) online check, use the command CheckLicence (without specifying a module number but using the Serial Number as ID) and set the parameter ForceCheck=true. This command just checks, if a license is locked or not. The check is logged on the Activation Server.

 

This could be used e.g. within an update to make a one time online connection to validate, if the key / ID was locked.
