Create Self-Signed Certificates for Web HMI Clients

Use the GE HMI Server Configuration Manager to create self-signed digital certificates for Web HMI clients to use when establishing a trusted relationship with OPC UA endpoints.

A new self-signed certificate generated by the GE HMI Server Configuration Manager overwrites the certificate you initially installed for the Web HMI client. Previously-configured OPC UA endpoints now require this new self-signed certificate. To reestablish this trust relationship, you must attempt to reconnect with the OPC UA server (using the Test button in the Server Credentials window). The OPC UA Server initially rejects the new client certificate (Bad Security Checks Failed). As a result, you must move the rejected client certificate in <project folder>\pki\rejected\ to <project folder>\pki\trusted\certs of the OPC UA server host machine.

  1. In the GE HMI Server Configuration Manager, select the OPC UA Client tab.
  2. To create self-signed certificates, select Enable Security.
    The Task panel shows the status of this step. The new self-signed certificates are stored in ProgramData\Proficy\WebHMI\DataServices\pki\own\certs.
