I have been trying to retrieve sensor data generated by OPC simulation server (data listed in excel file and read by OPC simulation) in to one of the custom modules in Azure IOT Edge. When the data logged in the console it shows me that data has not been logged in order. Following is the JSON for OPC publisher hosted in iot edge as a module.

Following is the published nodes json in gateway device.

Following is the screenshot of my excel sheet data

But the OPC publisher will not route the data in to modules in order that starting from anywhere but in order . For an example it sends starting from the row ,value 11 for Tag11 and then again sends the next row which has the value 17 for tag 11. And sometimes sends a batch of data. no proper order. This is not a issue with OPC server simulation since i have tested Simulation server with a standalone OPC client and it gets the data in order. Excel is read by simulation server. Appreciate any help on this.
