You will need to implement some hardware-in-the-middle to do it, which is sometimes another PLC also. Depending on the machine, sometimes it is easier and more cost effective by replacing the existing PLC with a newer generation which is connectable with OPC UA.
Thanks a lot

Yes, You are right.
But I have another Question as below.
If PLC Model & Hardware Connection Details available, Is it Possible to Access the DATA Values from PLC without knowing its Memory address?
Many Thanks.

Hi All,
we have an project which is using Very old PLC/Controller. Even we are not able to find the Device Model & brand.
But my company required to get some Data from that Controller to IIOT Device. Recommended me to use OPC UA to collect Details from PLC.
Did Explained that Can't make it without knowing the Parameter Details like Memory address & Data Type of the DATA inside the PLC. Still they insisted me to do that.
Any Possible way available to Integrate parameters of PLC through Modbus without knowing the Memory Address & Data Type of it.
