Remember that not every controller supports the deactivation of encrypted communication.

We strongly advise against disabling encrypted communication. Especially in connection with an enabled user management, encrypted communication should be enabled so that credentials do not fall into the wrong hands.

To disable encrypted communication with the controller again, proceed as follows:

  1. If the communication policy for encrypted communication is set to "Enforced", first set it back to "Optional".

  2. In the device editor, on the “Communication Settings” tab in the “Device” menu, disable “Encrypted communication”. If you have installed the CODESYS Security Agent, then you can also change the setting in the “Security Screen”.

    CODESYS establishes unencrypted communication again with the controller. Other clients can also communicate again without encryption.
