You need to generate a certificate for your PLC using a third party tool.

  • Generate a certificate and save it in the PKCS#12 format as .pfx file.
  • Additionally, export the certificate's public key as .pem file. This file can be used to verify the PLC's identity when downloading the configuration to a PLC.
  • You can find additional information on how to generate a certificate here.

For details, refer to Certificate Handling.
