Issues with Parsing Data

2min

If you are trying to convert the data type of topics going through the OPC UA server and have issues with viewing the data (you see null values), keep in  mind the following:
The OPC UA server can't convert data types of topics
The OPC UA server will work with the original data types coming from the topic
Solution: Parse Data before Sending to OPC UA Server
To resolve this issue, you will need to create a custom OPC UA tag by creating a JSON object and sending it to the appropriate topic. 
Refer to the following to learn more:
﻿Mozilla Developer Documentation - parseint()﻿
﻿Data Type Mapping﻿﻿
You can also review the following JSON file example that creates a flow to convert the data type of data before sending it to the OPC UA Server. See Manage the Flow Canvas﻿ to learn more about importing JSON files.
