Bosch Rexroth Safety Systems

Engineering Service delivers turnkey Bosch Rexroth Safety Systems engineering centered on the ctrlX AUTOMATION platform. The firm’s multidisciplinary control-systems team engineers functional-safety solutions using ctrlX CORE controllers, ctrlX I/O modules, ctrlX PLC Engineering toolchain and Bosch Rexroth drive integration. Services include requirements analysis, machine-level and plant-level risk assessment (per ISO 12100/ISO 13849), functional specification, safety architecture design to achieve SIL/PL targets, and FMEDA-backed justification where required. Typical implementations utilize certified safe motion functions—Safe Torque Off (STO), Safe Limited Speed (SLS), Safe Direction (SD), Safe Operating Stop (SOS)—and coordinate safe I/O with safety CPUs and dual-channel architectures. Network and protocol expertise covers PROFINET with PROFIsafe, EtherNet/IP with CIP Safety, OPC UA (with certificate-based authentication) for diagnostics, and seamless data exchange following ISA-88/ISA-95 batch/state models. Software development follows IEC 61131-3 programming practices, structured design patterns, and traceability workflows using requirements management and version control. Design and verification comply with IEC 61508, IEC 62061 and ISO 13849; cybersecurity controls are implemented per IEC 62443 guidance. Validation strategies emphasize virtual commissioning and staged testing. Engineering Service leverages ctrlX virtualization and containerized ctrlX apps alongside hypervisor platforms (VMware/Hyper-V), PLC-in-the-loop and hardware-in-the-loop (HIL) rigs to execute automated test suites prior to site work. Factory Acceptance Testing (FAT) includes scripted test protocols, requirement traceability matrices, and demonstrable acceptance criteria; Site Acceptance Testing (SAT) follows with performance tuning, drive parameterization, and operator scenario validation. Documentation deliverables comprise functional specifications, I/O lists, wiring diagrams, safety risk assessments, SIL/PL assessment reports, FMEDA outputs, and FAT/SAT test reports. On-site services include installation assistance, cabinet wiring verification, safety bus commissioning, drive commissioning with ctrlX DRIVE integration, and final validation. Engineering Service provides secure remote diagnostics via VPN and OPC UA with TLS/certificate authentication, asset management for spare parts, and long-term maintenance programs that include periodic revalidation, software lifecycle updates, and security patching. Training packages for operations and maintenance include hands-on labs with ctrlX PLC Engineering, safety diagnostics, emergency stop/lockout procedures, and troubleshooting. With proven experience in discrete machine retrofits and distributed production-line safety projects, Engineering Service delivers auditable, maintainable Bosch Rexroth safety solutions engineered to minimize commissioning hours and lifecycle risk while meeting regulatory and operational objectives.
