CODESYS Connectivity Redundancy is a license that unlocks functions in other product parts. These are functionalities that enable redundant communication between the controller and other devices. Communication redundancy ensures that communication can continue via the second path if one connection fails. This feature can be used independently of the CODESYS Redundancy with only a single controller.

MQTT is a Client Server publish/subscribe messaging transport protocol. It is light weight, open, simple, and designed so as to be easy to implement. These characteristics make it ideal for use in many situations, including constrained environments such as communication in Machine to Machine (M2M) and Internet of Things (IoT) contexts where a small code footprint is required and / or network bandwidth is limited.

Janz Tec developed a CODESYS library which implements the MQTT protocol. This way users can add the MQTT protocol easily to their own IEC 61131 applications. The Janz Tec MQTT library for CODESYS implements client functionality. It is completely written in IEC code which guarantees the library can be used on any type of target system.
