Machine safety
Safety controllers, emergency stop, safety switches and drive monitoring – integrated with the machine control.
Machine safety is not an add-on fitted at the end. We group the safety functions into a separate safety architecture, connect the safety equipment in the field and share the safety status with the machine control, so the operator always sees why the machine has stopped.
The approach is the same for new machines and for existing machines whose electrical and control systems are being renewed.
What it includes
Safety control systems
Design and programming of safety functions on a safety controller separate from the main PLC.
Safety I/O and communication
Signal acquisition via safety input/output modules and safety networks (e.g. Safety over EtherCAT).
Emergency stop circuits
Connection of emergency stop buttons and stop circuits to the safety system.
Safety switches and sensors
Integration of door and fence switches, safety light curtains and other safety sensors.
Drive and contactor monitoring
Monitoring of contactor feedback (EDM), braking, speed and direction of motion.
Integration with the machine control
Safety and standard control in one architecture, with the safety status visible on the PLC and HMI.
Where it is used
- New machines and lines
- Renewal of safety circuits on older machines
- Robot cells and guard fences
- Escalators, cranes and conveyor systems
How we work
- Assessment – review of the machine operation, existing safety equipment and control system.
- Safety architecture – definition of the safety controller, I/O, communication and stopping method.
- Implementation – installation of safety circuits, switches and sensors in the cabinet and on the machine.
- Software and integration – programming of safety functions and integration with the machine control.
- Testing and commissioning – on-site verification of every safety function before the machine is handed over.
Benefits for you
- Safety functions designed together with the machine control
- Faster diagnostics – the operator sees why the machine stopped
- Every safety function verified before the machine is handed over
- The same approach for new and existing machines
