Note: Without a valid license, DBGW Add-On instruction will still have full functionality, but will only work for 50 successfull executed queries. By restarting Windows DBGW service, 50 new executable queries are available.
PS! Only the first 2 PLCs, after a restart, without a license can be connected to Windows DBGW service.
1. Before purchasing one or several licenses, you need to know at least 1 serial number for 1 PLC.
2. There is three ways to find PLC Serialno
2.1 Using Logix Designer (must have been online with PLC at least once):
Click on Controller icon (within blue circle) and select tab “Advanced” and note Serial number

2.3. Using DBGW Add-On instruction
Serial number can be copied directly from the DBGW Add-On instruction, if Logix Designer is online with the PLC
