Embedded Edge Calculation Coprocessing for PLCs
Offload IF97 steam/water, mass flow, and energy calculations to a dedicated module—connected via Modbus RTU over RS‑485 and mapped directly into your PLC holding registers.
On-edge coprocessing for critical energy calculations
The Helix Energy Transfer module is a DIN-rail mounted embedded coprocessor designed to sit beside your PLC and handle intensive thermodynamic and flow calculations.
