Larus — Use Cases

Strix.Monitor: SCADA Replacement​

Challenge: Modernize APCS by replacing legacy Western PLCs and SCADA with a Russian stack without production shutdown.

Solution: Larus-100 (control logic) + Strix (visualization and alerts)

Replacement scheme:

"Before":                           "After":
Siemens S7-400                     Larus-100
Profibus DP                        Modbus RTU / EtherNet/IP
WinCC SCADA                        Strix.Monitor

Parallel operation strategy:

  1. Install Larus-100 alongside the existing PLC (Larus as OPC UA Client)
  2. Migrate logic block by block, test in shadow mode
  3. Switch control to Larus-100 during scheduled maintenance
  4. Remove old PLC

Example: Highlandgold (mining complex)

  • Replaced Yokogawa CENTUM VP with Larus-100 + Strix
  • Flotation and thickening APCS
  • 340 I/O points, 12 PID loops
  • Implementation timeline: 6 months

Thermal Processing APCS​

Challenge: Control thermal furnaces (annealing, quenching, tempering) with precise temperature profile management.

Solution: Larus-100 + AI-8 modules (K-type thermocouples) + DO16 (burner control)

Thermal processing APCS (Larus-100)

Implemented functions:

  • PID control for each zone
  • Programmable temperature profiles (heat/soak/cool curves)
  • Deviation alerts, event logging
  • OPC UA server for MES/1C integration

Gas Distribution APCS​

Challenge: Monitoring and control of a gas distribution substation.

Solution: Larus-100 (control) + Larus-10 (remote point monitoring) + Strix

Key features:

  • Autonomous operation (connection loss → local emergency logic)
  • Redundancy: hot standby Larus-100 (Active/Standby)
  • Integration with SCADA dispatch (OIK) via IEC 60870-5-104

Test Benches​

Challenge: Automate test bench data acquisition with high-speed collection and deterministic control.

Solution: Larus-100 (control + synchronized acquisition) + Passer-V2 (vibration)

Real-time requirements:

  • Larus-100 with Forte provides FB execution cycle down to 1 ms (1 kHz)
  • PTP synchronization with Passers (±1 μs)
  • Deterministic emergency protection (<10 ms from event to shutdown)

Digital Transformation: Unified Stack​

"From sensor to APC" concept:

Unified stack «from sensor to APC»

Unified stack advantage:

  • One vendor = one accountability
  • No compatibility issues between levels
  • Unified support SLA
  • Compliance with FSTEC / CSII requirements for CII
