CODESYS supports a wide range of common fieldbus systems with integrated configurators and protocol stacks in the form of platform-independent libraries.
Overview of the supported protocols:
How can you use fieldbus support in CODESYS?
You are a system integrator or a user in the machine/plant construction sector or the like:
- Use controllers that are equipped with the integrated CODESYS fieldbus support.
- Millions of CODESYS-compatible single devices and over 1,000 different device types from more than 500 manufacturers offer you a large range of hardware for your automation projects. CODESYS Inside offers a selection of manufacturers that offer CODESYS-compatible devices.
- You can also use the CODESYS Control SoftPLC systems from the CODESYS Store as an alternative.
- The most common fieldbus systems can be used immediately.
You are a manufacturer of programmable devices:
- Purchase the CODESYS Runtime Toolkit with fieldbus support
Products
CODESYS offers seamlessly integrated communication protocols for a wide variety of interfaces and requirements.
OPC Server
Standard Interface to access the IEC 61131-3 process data of a controller via Open Platform Communications.
OPC UA
Standard Interface for Communication in Smart Factory and Industry 4.0 Systems
PLCHandler
Compact software interface (API) for easy access to the PLC variables in CODESYS controllers from external systems
BACnet
Configurator and protocol stack fully integrated in the IEC 61131-3 Development System
Serial interfaces
Although today almost every industrial controller has an Ethernet connection, serial interfaces are still installed in many industrial devices. This allows, for example, for the connection of appropriately equipped sensors and actuators or extensions.
Standard Ethernet
How does CODESYS communicate via Ethernet? How can I send and receive data from a CODESYS-compatible PLC via TCP or UDP? How can I realize data exchange from the PLC application?
IIoT libraries
All IoT communication protocols can be implemented and used on different transmission media via software.
Other communication options
If a physical port is available on a controller, communication protocols can usually be implemented simply via software, either as part of the IEC 61131-3 control application or as separate library modules. Data exchange is performed by explicitly calling functions or function blocks as part of the logic control.
Proprietary communication protocols
CODESYS supports the most common standard communication protocols for data exchange between controllers, such as OPC UA. In addition, Ethernet-based fieldbus systems such as PROFINET or EtherNet/IP™ make it easy to exchange data between controllers by implementing master and slave functions.
