• Fieldbus – PROFIBUS DP-V1, CANopen, HART pass-through
• Network redundancy – dual media, seamless switch-over < 1 ms
• Time sync – SNTP or GPS for SOE and control loop synchronization

• Real-time DSP – FFT, FIR/IIR filtering, vector control algorithms executed in hardware
• Hot-swap – online module replacement without stopping the rack
• Self-diagnostics – LED fault map, web-based status page, SNMP traps
• Programmability – ladder, C/C++, MATLAB-generated code; IEC 61131-3 compliant
• Data retention – non-volatile flash; configuration survives power loss indefinitely
• Expandability – plug-and-play extension cards for extra I/O, communication or motion axes

• Petrochemical: reactor temperature/pressure cascade control, pump skid monitoring
• Power generation: turbine excitation, generator protection, substation RTU gateway
• Manufacturing: robot trajectory planning, high-speed packaging line coordination
• Water & wastewater: chemical dosing loops, remote pump station telemetry
• Building automation: HVAC optimization, energy metering, lighting control networks
