labelQINSy Config

QINSy Configuration

To configure the OPC plugin with QINSy the driver must be added to the template and a Generic Driver .xml must be created.

Database Setup

The driver can be found under Output Systems -> OPC Server Plugin. The OPC Plugin is designed to work with the Generic Driver output and by default this driver listens to : 51234. (Port number can be changed in the registry.)

Subsequently you have to add a Network - Generic Output driver with default settings : 51234.

Generic Layout editor

To receive data with OPC a output driver .xml should be created in the Generic Layout Editor. It is important that the driver is outputting in JSON format so it can be read into a OPC server:


To select data which has to be outputted by the Generic Driver consult out knowledge base Generic Layout Editor


labelQINSy Online

QINSy Online

In online mode QINSy will open a Generic Output to UDP 51234 window, in here the .xml should be added:

The saved .xml will automatically be recognized when saved in the directory C:\Users\Public\Documents\QPS\QINSy\Drivers\Definitions\Output. If you have multiple .xml files select the correct one and go to the next menu:

In the Output Message Wizard you can change the output settings. Check if the Output Type is still JSON and select finish:

In the main Generic Output window the .xml file is shown with the the data which is outputted by the driver:

labelAdditional Info
