Pilz Industrial Networking

Engineering Service’s Pilz Industrial Networking offering delivers hands-on engineering, integration, and lifecycle support for safety-critical networks built around the Pilz PNOZmulti 2 platform. The firm engineers safety-controller architectures, interlocks, and distributed I/O topologies using Pilz PNOZmulti 2 controllers and the PNOZmulti Configurator development environment, and integrates Pilz PSS family controllers where higher-level motion or logic is required. Network designs include deterministic industrial Ethernet backbones (Profinet, EtherNet/IP, EtherCAT) and safety layers using PROFIsafe or SafetyBUS p to meet application SIL/PLe objectives. Design activities follow IEC 61131-3 programming conventions, IEC 61508 lifecycle practices, ISO 13849 risk-reduction mapping, and manufacturing models per ISA-88/ISA-95. Deliverables include a functional specification, detailed I/O lists, signal architecture, safety requirements specification (SRS), and wireable schematics. Software development applies structured design patterns, version-controlled PNOZmulti Configurator projects, and peer-reviewed code to reduce validation effort. Testing and validation use model-based simulation, controller emulation and virtual commissioning with digital-twin integration (OPC UA), hardware-in-the-loop (HIL) tests, and formal Factory Acceptance Testing (FAT) protocols. FAT documentation conforms to project-specific test matrices and includes traceability to requirements and safety validation per IEC 61508/ISO 13849. On-site Site Acceptance Testing (SAT) and performance optimization validate network QoS, VLAN segmentation, and redundancy using industrial switches (e.g., Hirschmann, Moxa) and firewall appliances (Phoenix Contact mGuard, Cisco Industrial). Cybersecurity and network hardening are implemented to IEC 62443 standards: role-based access, managed switch ACLs, VPN-secured remote diagnostics, and secure firmware lifecycle management. Support services include remote diagnostics, 24/7 incident response, spare-part management, scheduled maintenance, and long-term software lifecycle plans to manage Pilz firmware updates and obsolescence. Training and handover cover maintenance-level troubleshooting, PNOZmulti Configurator project management, safety parameter changes under lock-and-tag procedures, and operator-level interactions. For procurement and plant managers, Engineering Service provides clear BOMs, FAT/SAT evidence, and change-control workflows to ensure the Pilz PNOZmulti 2 solution meets production, safety, and regulatory objectives across the machine lifecycle.
