Control and safety products
Automation Portfolio
The portfolio combines CODESYS engineering, runtime, visualization and motion functions with application-specific machine-safety components. Standard control and functional safety are engineered as separate responsibilities and integrated through defined interfaces.
Controller runtime
SoftPLC and virtual-control options turn compatible industrial or embedded platforms into application controllers.
Visualization
Target, web and remote visualization provide operator access without separating HMI engineering from the control project.
Motion and robotics
PLCopen motion, coordinated axes, CNC functions and robotic kinematics can be added where the machine requires them.
Machine safety
Software-integrated safety and independent field-safety components cover different parts of the safety architecture and must be selected against the machine risk assessment.
Industrial communication
Fieldbus, industrial Ethernet, OPC UA and MQTT connect the controller to devices, supervisory systems and edge applications.
Applications
Solutions
Use the platform for machine control, distributed software controllers, motion-enabled equipment and safety-related machinery with hardware and software selected for the application.
Machine automation
Combine logic, visualization, recipes, alarms and device communication in one project for stand-alone machines and production equipment.
Distributed control
Deploy runtime instances on industrial PCs or embedded controllers while keeping common engineering methods across machine variants.
Motion-enabled equipment
Coordinate drives, axes and process logic from the same application when sequence and motion behaviour must remain synchronized.
Safety-related machinery
Combine certified or otherwise approved safety software and controllers with suitable relays, safety sensors and safe-motion functions. The complete safety function must be validated against the required PL or SIL.
System architecture
Platform
A typical system separates engineering, runtime execution, visualization, field communication and controller operations while maintaining a controlled application model.
Engineering workstation
Develop and test the application, configure devices and maintain reusable libraries.
Controller target
Run the application on a compatible PLC, industrial PC, embedded controller or virtualized control platform.
Operator layer
Present machine state, alarms, trends and commands through local or browser-based visualization.
Operations layer
Connect controllers to supervisory systems and manage deployed projects through supported server services.
Control
Engineering
The CODESYS Development System implements IEC 61131-3 and brings programming, device configuration and diagnostics into one workflow.
IEC 61131-3 languages
Use Structured Text, Ladder Diagram, Function Block Diagram and Sequential Function Chart according to application and team practice.
Device and fieldbus setup
Configure supported devices, networks and I/O mappings alongside the control application.
Commissioning tools
Online monitoring, forcing, trace, watch lists and breakpoints help verify machine behaviour during startup.
Reusable software
Libraries, interfaces and project templates support controlled reuse across machine families.
One engineering workspace for the controller application
Programming editors, device and fieldbus configuration, visualization design and online diagnostics are brought into a common project environment. This keeps software, I/O mapping and commissioning information aligned as the machine is developed.
- IEC 61131-3 programming and reusable application structures
- Integrated device, fieldbus and visualization engineering
- Online trace, monitoring and debugging during commissioning
Control
Runtime
The runtime layer executes the control application and provides the device interfaces needed by the selected target.
SoftPLC deployment
Use compatible Linux, Windows or embedded targets where a software controller is appropriate.
Task configuration
Separate cyclic, event-driven and background tasks according to timing and workload.
Device abstraction
Keep the application portable by isolating hardware-specific I/O and communication details.
Operational recovery
Define startup, watchdog, retained-data and update behaviour for the actual machine environment.
Control
Visualization
Visualization is engineered from the same project so variables, alarms and user actions stay aligned with the controller application.
Local HMI
Run operator screens on a panel PC or controller-connected display.
Web visualization
Serve browser-based interfaces to authorized clients on the machine or plant network.
Operations content
Build trends, alarms, recipes, user roles and diagnostic views around the machine workflow.
Responsive layouts
Adapt screens to the target display rather than duplicating the control project for every device.
Control
Motion
Motion functions can be introduced where coordinated positioning, path control or robotics are part of the machine sequence.
Single and coordinated axes
Use PLCopen-aligned motion blocks for positioning, gearing, camming and synchronized movement.
CNC and path control
Add interpolation and path planning where the machine follows defined trajectories.
Robotic kinematics
Integrate supported kinematic models with the PLC application for coordinated machine and robot behaviour.
Drive integration
Match bus cycle, drive profile, feedback and safety functions to the required motion performance.
Functional safety
Machine safety and safe automation
Machine safety is designed from the risk assessment. Depending on the application, the safety chain can include emergency-stop devices, guard switches and locking, light curtains, scanners or radar, safety relays, configurable safety controllers, safe I/O and safe motion.
Safety runtime and engineering
Use compatible safety controllers and CODESYS Safety components only within supported and certified architectures for the intended safety function.
Safety relays and controllers
Monitor emergency stops, guards, light curtains and other safety functions with components selected to the application complexity.
Safety sensing
Apply guard switches, locking devices, light curtains, scanners or area monitoring according to the hazard and access concept.
Safe motion
Monitor standstill, speed and motion limits where access during setup or maintenance is required.
Control
Communication
Communication is selected around ownership of the data, required cycle time and the systems that consume it.
Industrial Ethernet and fieldbus
Connect supported EtherCAT, PROFINET, CANopen and other device networks through the appropriate master or slave components.
OPC UA
Expose structured controller data to SCADA, MES or edge systems with authenticated and encrypted sessions where configured.
MQTT
Publish selected machine data to an MQTT broker without treating cloud connectivity as part of the deterministic control loop.
Protocol boundaries
Keep safety, real-time control and business-data traffic separated according to their timing and security requirements.
Controller operations
Automation Server
CODESYS Automation Server supports centralized management of connected controllers, applications, projects, users, certificates and authorized remote-service workflows. The deployment model and network access must follow the plant cybersecurity policy.
Controller inventory
Organize supported controllers and their project associations in a managed environment.
Remote deployment
Deploy applications and supporting files to authorized targets using defined user permissions.
Project coordination
Maintain shared project access and controlled transfer between engineering and operations teams.
Deployment model
Review the SaaS service and the current on-premises product availability against cybersecurity, network, data-sovereignty and governance requirements.
Centralized controller and project management
Controller inventory, project coordination, remote maintenance and application deployment are handled above the runtime layer. The operating model, network access and user permissions still need to match the plant cybersecurity policy.
- Central view of connected controllers and application status
- Controlled project and application deployment workflows
- Remote access governed by roles, certificates and network policy
