Series
Part of GE’s Mark VIe Speedtronic platform, designed for distributed control in critical industrial applications.
Key Features
- Multi-Protocol Integration: Unified support for industrial Ethernet & legacy serial protocols.
- Deterministic Communication: <100 μs latency for time-sensitive control loops.
- Dual-Homing Redundancy: Zero-failover switchover (<10 ms) via HSR/PRP.
- Secure Data Exchange: Hardware-based firewall with VLAN segmentation.
- Plug-and-Play: Auto-configuration with Mark VIe ToolboxST™ software.
- Seismic Rating: 5g operational (IEC 60068-2-6).
Function/Role
Acts as a networked communication hub, enabling:
- Real-time data exchange between Mark VIe controllers.
- Integration with plant-wide DCS/SCADA via OPC UA or Modbus TCP.
- Synchronization of distributed I/O modules using PTPv2.
Purpose/Use
- Control Network Bridging: Connects Mark VIe racks in redundant topologies.
- Legacy System Integration: Interfaces with serial-based subsystems (e.g., excitation controls).
- Cybersecurity Enforcement: Implements VLANs and port security for network segmentation.
- Time-Critical Messaging: Ensures synchronized timestamping for protection sequences.
Application Fields
- Power Generation:
- Gas/steam turbine control networks (TMR configurations)
- Plant-wide DCS integration (data historians, alarm management)
- Wind farm controller communication
- Oil & Gas:
- Turbine-compressor anti-surge control synchronization
- LNG process skid monitoring via Modbus RTU
- Industrial Manufacturing:
- High-speed compressor control loops
- Paper mill drive synchronization
- Grid Infrastructure:
- Substation automation (IEC 61850 GOOSE messaging)
- Black start generator control
- Marine:
- Integrated propulsion control systems (IPCS)
- Dynamic positioning data links
This module ensures deterministic, fault-tolerant communication in GE’s Mark VIe systems, critical for synchronizing protection relays, governor controls, and safety interlocks in mission-critical environments. It is typically deployed in pairs for redundancy within control racks like the IC693CHS397.
