ADS encryption

MQTT can also be used to enable encrypted ADS communication through the capability of TLS, which is used for the encryption of MQTT at transport level.
The broker can be installed locally on the PC-based controllers for this. In doing so the broker is configured so that it merely offers the local controller as an access point in a virtual Ams Network.

If encryption is then activated and used, this creates a TLS-based secured connection via ADS to a TwinCAT system.

ADS connections can be blocked by the firewall if this is used.
