Licensing

This program module constantly checks the license. If you have not yet purchased a license, you can do so by e-mail to [e-mail] or online via Selmo Studio. For licensing you need a request ID named "GVL_Global.strRequestID", which is automatically read by the program module. The purchased license key must then be entered under "GVL_Global.strLicenseKey". If no licensing has been performed, the entire PLC program is in demo mode. In this mode the 'automatic operation release' is reset after 30 minutes. Please note that this program block is called only once per PLC! The checksum is used for consistency checking and, in case of inconsistency, resets the 'automatic operation release' after 30 minutes, even if a license key is present. If necessary, this can be checked with the two boolean variables "GVL_Global.xLicenseValid" and "GVL_Global.xChecksumValid".
