Inquiry of Data Exchange (regarding OPC, Edge Link, etc)
Posted: 20 Feb 2020, 05:33
Hello members,
Currently I am facing technical difficulty on data exchange that I need to ask your kind support.
Our data flows as described below, and the requirement is
"there must not be any request from Data Exchanger to OT Componenet."
PLC or SCADA --> OT Component --> Firewall --> Data Exchanger --> Firewall --> Cloud
With my knowledge, however, OT component cannot push data to Data Exchanger without getting any request.
1. OPC UA does not support pub/sub function at the moment. (I believe it is under developing).
2. Edge Link of Advantech is also working with Data Polling method which requires request and response to exchange data.
I would really appreciate if anyone shares the idea to resolve my difficulty.
Thanks in advance.
