    There can be found a wide topics covering how to ENABLE forced certificates on OPC-UA, but there is nowhere to be found on how to disable it again. Once it has been enabled, I can not go back to plain text communication or just authentication with username and password.

    I know the following setting for the cfg file:
    [CmpOPCUAServer]
    SECURITY.CommunicationMode=SIGNED_AND_ENCRYPTED

    from some V3.5.16.10 documentation found online, I know there is the following setttings in the OPCUA server, but what is the correct syntax to configure them as the one above here?

    Enumeration Type Documentation

    enum CmpOPCUAServer_SecurityPolicy
    Enumerator:
    CmpOPCUAServer_SecurityPolicy_Basic128Rsa15
    CmpOPCUAServer_SecurityPolicy_Basic256
    CmpOPCUAServer_SecurityPolicy_Basic256Sha256

    enum CmpOPCUAServer_CommunicationMode
    Enumerator:
    CmpOPCUAServer_CommMode_OnlyPlaintext
    CmpOPCUAServer_CommMode_PlainAndSecure
    CmpOPCUAServer_CommMode_MinSigned
    CmpOPCUAServer_CommMode_SignedAndEncrypted

    enum CmpOPCUAServer_Activation
    Enumerator:
    CmpOPCUAServer_Deactivated
    CmpOPCUAServer_Activated

    enum CmpOPCUAServer_UserAuthentication
    Enumerator:
    CmpOPCUAServer_UserAuthentication_Disabled
    CmpOPCUAServer_UserAuthentication_Enabled
    CmpOPCUAServer_UserAuthentication_Enforced

    enum CmpOPCUAServer_AllowUserPasswordOnPlaintext
    Enumerator:
    CmpOPCUAServer_AllowUserPasswordOnPlaintext_Yes
    CmpOPCUAServer_AllowUserPasswordOnPlaintext_No

    Is it just the enum alias and then the settings? Is there a manual for this stuff anywhere?
