I have a requirement to write values to tags using two different interfaces, below is the scenario, looking for best way to implement it.
Data is being written to tags from source using OPC interfaces, now when the source goes down we want to write data to these tags(using data files) via different methods, for ex UFL.
We do not want to use ACE or write code to get the data.
We do not want to stop the OPC interface to collect data via UFL, we are expecting a buffer lock for these tags, as the tags are already active under the OPC interface.
Can you guys share us your thoughts on this.
Thank you in advance
