Hello,
I’m trying to connect a python OPC UA client to AXC F 2152 controller with enabled OPC UA server to establish a both side communication and data exchange, primary data from PLC to pytthon3 OPC client module and after them to Rpi App like Openhab.
User:admin, PW:devicePW, security policy: Basic256 SHA256 algorithm.
Using OPC UA OPC UA-self-signed_certificate.crt and OPC UA-self-signed_publickey.pem downloaded via WBM to external device directory.
How should be programmed correct client file please ?
On a external Raspberry Pi is Python3 and module for python client installed.
GitHub - FreeOpcUa/opcua-asyncio: OPC UA library for python >= 3.7 OPC UA library for python >= 3.7. Contribute to FreeOpcUa/opcua-asyncio development by creating an account on GitHub. client_error.zip

pip install opcua

Thanks for help. P.S.
I’m trying to make it work without security policy.

Using opcua-asyncio installed on Rpi is working well (without SHA256 - non secure communication).
Installing internal on PLC controller isn’t working :0(
Maybe native opc client module would be OK, but I’m not a company, so I can’t download it.
If it’s not instalable, then using nodered PLC app is a way.
Important question is if nodered has openhab modules (standart has some OH modules) and how can be information transfered from the opc client module to openhab2 running on PLC.
