Fault at connection to OPC Server on PLC Simotion
Posted: 01 Dec 2020, 11:01
Hello,
I'm quite new on OPC UA communication.
I'm using UAExpert to connect to the OPC server. When launch connection I obtain a popup to trust the certificate sent by the PLC Simotion D425. I can trust it but I get 3 errors at each time I try to connect.
Unable to get local issuer certificate [BadCertificateChainIncomplete]
Unable to get certificate CRL [BadCertificateRevocationUnkwown]
Unable to verify the first certificate [BadCertificateChainIncomplete]
When contacting Siemens they tell me that this is because the server cannot manage client certificates and that I need to create my own and load it into the PLC.
Does this seems right?
From what I understand I would say there is a problem with the certificate in the PLC.
