Enables communication using the DNP3 protocol in CODESYS applications. A CODESYS PLC can be configured and used as an outstation.

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.

CODESYS KNX consists of a configurator for I/O channels, a KNXnet/IP protocol stack in the form of a runtime system component, and a data exchange function with the ETS5 configuration system. This allows any CODESYS-compatible device to be expanded to function as a KNX subscriber and to communicate with KNX I/Os.

CODESYS SoftMotion is an additional option for CODESYS compatible SoftPLC systems. CODESYS SoftMotion extends the functional scope of these systems from a purely logical controller to a motion controller, optionally also with CNC and robotics support.
