Software consist of 2 parts:

Part 1: Windows Service program (called DBGW-Service) installed on a Windows computer or on a Virtual Machine (Windows OS) in Microsoft Azure Cloud, Amazon Web Services or Google Cloud Platform

Part 2a: Rockwell PLC’s: DBGW Add-On Instruction imported into each of your Compact- or ControlLogix PLC-program

Part 2b: Siemens PLC’s: Drag and drop DBGW Function Block from DBGW library into each of your S7-1200 & S7-1500 PLC-program


The PLC Add-On instruction/Function block DBGW is licensed to the PLC’s unique serial number.

No license on Windows DBGW-Service program, therefore no additional cost for implementing redundant database access or accessing both local and Cloud databases.
