We have OPC UA server with an integer tag .
We could connect to the OPC Server using Ignition.
We have timer based client script firing every 10 ms to write to the integer tag with value of 50 as shown below
We could see the memory growth for every write.
We have observed the traffic using Wireshark . We could see for every OPC UA write there is a OPC UA read is performed .
We suspect this additional OPC UA Read may cause the memory increase.
Could you please help us why there is additional OPC UA Read while using Ignition?
