The new application-based licenses are completely independent of the hardware used and can be used across all products. They thus offer maximum flexibility in the choice of devices. Another advantage is the scaling of the licenses via metrics of the application. So you only pay for exactly as much CODESYS as you use.

One license! From small embedded devices to large IPC solutions, always a perfect fit!

Description of properties

A detailed description of the properties listed above can be found in the “CODESYS Control Application-Based Licenses” data sheet.

Trial Operation

A controller without a license runs for 2 hours in trial mode. After that, the runtime system is terminated and must be restarted. Functionally, trial operation is not restricted. Unlicensed functions have a shorter trial runtime (e.g. fieldbuses run for 30 minutes).

License check

If an application-based license is available on the controller, all criteria are checked against the limit specified in the license. If a criterion exceeds the defined limit, a download of the application or the loading of the boot application is prevented. The system does not switch to trial mode.

This prevents live applications from falling back into a time-limited trial mode.

Upgrade licenses

Each performance class (Runtime, Visualization, OPC UA, Motion) offers upgrade licenses that allow switching from a smaller license to any higher license. A change from a larger license to a smaller license is not supported.

Restriction with other store products

Application-based licenses can be combined with other store products, unless explicitly excluded. The I/O channels of additionally purchased fieldbuses are taken into account in the I/O channels license metric and are also counted.

How do I find the right license?

Answer the following questions to find the right runtime system license for your application.

1. Which fieldbus is needed? How many fieldbus instances?

2. How many input and output channels are needed in the application?

3. Do you plan to implement additional functions and logics?

4. Do you want to assign tasks or task groups to specific cores to achieve higher performance or optimized realtime behavior?

Case study 1: Porting an existing application

The PLC of an existing plant is to be modernized. Over the years, own libraries have been which are also to be used on the new PLC. The sensors and actuators of the plant are connected via two CANopen master instances, but EtherCAT is to be used in future models. In total the plant has about 200 digital E-A signals

• 2 CANopen master instances: at least license Basic M

• Option: EtherCAT Master instance: at least license Standard S

• 200 E-A channels: at least license Basic L

• Additional libraries are used: 3 MB code of license Basic L allow a lot of additional logic.

• Real-time behavior: In the range of 4-10 ms

-> License CODESYS Control Basic L is required per device.

-> Option with EtherCAT Master instance: License CODESYS Control Standard S is required per device.

Case study 2: Standard application with EtherCAT

A new application for a machine with EtherCAT is to be developed. In addition a connection to the cloud for data analysis via MQTT is to be implemented. The machine has about 800 E-A signals. Since the PLC has to command simple drives, the real-time behavior of the bus task is very important. Additionally an existing C-code library shall be connected and a small web visualization for commissioning should be developed.

• EtherCat instance: at least license standard S

• 800 E-A channels: at least license standard M

• Additional logic to connect to the cloud: 5 MB code of license Standard M allows a very large application.

• Separation of the bus task on its own core : at least standard L

• Connection C code: Dynamic C code included in Standard L.

• MQTT protocol: CODESYS IIoT Libraries SL license required

-> The CODESYS Control Standard L and CODESYS IIoT Libraries SL licenses are required per device.

Case study 3: Supervisor PLC with Profinet

A PLC monitors a production line in a plant. The application is to collect the data via a Profinet network, process it and and control the individual plant components. In addition, an HMI based on web technology is needed to maintain the plant. Lastly, production data must be transmitted via MQTT for higher-level data analysis.

• Profinet instance: at least license standard S

• 1,500 E-A channels: at least license standard L

• A lot of logic due to multiple monitoring and cloud connection: 6 MB code of license standard L allow very large applications

• HMI for maintenance: at least CODESYS Visualization M

• Use of MQTT: CODESYS IIoT Libraries SL license is required.

-> CODESYS Control Standard L, CODESYS Visualization M and CODESYS IIoT Libraries SL licenses are required per device.

Case study 4: Application with 2D portal and a four-axis SCARA robot

A PLC is to control a 2D portal and a SCARA robot with 4 axes via EtherCAT, as well as an additional 2 drives for a conveyor belt and a rotary table. Further functions are not planned.

• EtherCAT instance: at least license standard S

• 200 E-A channels: License Standard S is sufficient

• Mainly use of CODESYS libraries whose code size is not taken into account in the licensing: 3MB code of the Standard S licence is sufficient.

• Increased real-time requirement: at least Standard L to use multi-core functionality.

• Control of 8 axes in total: SoftMotion Axis (8) license for 8 axes

• Control of 2D portal and SCARA robot: SoftMotion Axis Groups/CNC Interpolators (2) for 2 axis groups

-> CODESYS Control Standard L, CODESYS SoftMotion Axis (8) and CODESYS SoftMotion Axis Groups/CNC Interpolators (2) licenses are required.
