Dear Ignition Team,
I am from digital transformation team of Saint-Gobain india. We have a requirement to connect Yokogawa ExaOPC-DA server to ignition server. We are using ignition platform for process data historian application. Our plant security guidelines suggests to use OPC-UA to communicate across the firewall. Since yokogawa only supports OPC-DA right now.
What we have already tried and succeeded:
- We have installed KEPServerEX on Yokogawa server and configured it as OPC-DA client. KEPServerEx converted this connection to OPC-UA and the ignition gateway was able to browse tags using OPC UA Client configuration.
2)We have developed Python OPC DA client using OpenOPC library and installed this program as windows service. This service was able to connect to Yokogawa ExaOPC-DA and extracts process values.
please provide us the clarity on following questions
-
How can we achieve the aforementioned scenario with ignition components and products from inductive automation?
-
Yokogawa ExaOPC-DA server has many instances running on different physical machines, can we have redundant OPC-UA connections from ignition gateway?
-
If ignition doesn’t support OPC-DA/UA conversion, what will be the recommended third party middleware which can be used?
Thanks & Regards,
