Hello,

      Is it possible to Read Json file and update Tag values in Kepware?. We have a legacy system which creates JSon files with the data and we would like to have this data in Kepware Tags.

 

Thanks & Best Regards,

Gowtham K.

  • JSON files created and saved at any file system?
  • What protocol the legacy system is using?

Hi @GK_10031290 

 

Kepware can't read JSON files, you might need some workaround to transform this data so that it can be read by Kepware. My suggestion is you need to install Node-RED, read the JSON with Node-RED, and create an OPC UA server in Node-RED. Make this JSON data available in the OPC UA server then you can read all of the tags via the OPC UA from Kepware

 

Hope this helps you

 

Thanks
