ENGtron Knowledge
Hands-on knowledge from test bench engineering
What we learned planning, building and operating our own test benches, written down for development engineers and everyone who builds or runs test benches: real-time software, safety and test methodology.
Real-time & software
Linux real-time on the test bench: determinism without expensive special hardware
Why Linux with PREEMPT_RT is enough for test benches: deterministic 1 ms control cycles, EtherCAT connectivity, limits compared to Speedgoat & co. and practical tips.

Your own test bench software: control, live visualization and automated test cases
Self-developed control and visualization software for test benches: no licence costs, automated test cases via Python or CSV setpoint files, live visualization at 10 ms, RT logging at real-time cycle time (1 ms).

Safety concept for test benches: from risk assessment to emergency stop
Securing a test bench: risk assessment per EN ISO 12100, guards, emergency stop, safety PLC (e.g. Pilz PNOZmulti) and why safety never belongs in the test software.

Hardware-in-the-loop (HiL) explained: real hardware, simulated world
What hardware-in-the-loop (HiL) is, how a HiL test bench tests drives and actuators against a real-time simulation and why this drastically reduces field testing.
