Part of GE’s Mark VIe Speedtronic platform for critical industrial automation.
Key Features
- Deterministic IRT Support: Hardware-based Isochronous Real-Time (IRT) for motion/time-critical control.
- Dual-Network Redundancy: MRP/MRP-Ring support (< 200ms failover).
- Secure Integration: VLAN segmentation, HTTPS/SSH encryption, and role-based access control.
- OPC UA Tunneling: Seamless data routing to enterprise systems.
- ToolboxST™ Integration: Automatic device discovery and topology mapping.
- Industrial Ruggedness: Conformal-coated PCB (humidity/dust resistance) and 15g vibration tolerance.
Function/Role
- Acts as Profinet Controller for Mark VIe systems:
- Synchronizes I/O data exchange with drives/valves/sensors.
- Manages deterministic control loops (e.g., turbine governor commands).
- Bridges Profinet networks to Mark VIe’s core Ethernet backbone.
Purpose/Use
- High-Speed Machine Control: Precision motion synchronization (≤1ms cycles).
