Industrial System Integration & Commissioning
Special-purpose machinery, PLC safety logic, and high-consequence commissioning.
Boehm Group, Thuringia
Overview
Engineering, wiring verification, safety integration, and commissioning of custom manufacturing cells and special-purpose industrial machinery.
Challenge
Moving from multi-thousand-page electrical diagrams and mechanical CAD assemblies to a machine that powers on for the first time without component destruction or safety violations.
Approach
Rigorous step-by-step commissioning methodology: point-to-point I/O validation, emergency-stop loop qualification, fieldbus topology verification, servo tuning, and defensive exception handling.
Architecture

Safety Circuit Architecture: Dual-channel fail-safe interlocks conforming to ISO 13849-1 / SIL 3 standards.
- 02
Fieldbus Topology: Deterministic PROFINET / EtherCAT rings connecting distributed remote I/O nodes and servo drives.
- 03
Power Distribution: 400V 3-phase balancing, selective circuit protection, surge suppression, and 24V DC auxiliary routing.
- 04
Diagnostics Engine: Timestamped event logs and alarm state trees allowing technicians to reconstruct root cause in seconds.
