FAQ

• What is IONet?
  IONet is GE's proprietary high-speed, deterministic Ethernet network used within the Mark VIe control system for real-time data exchange.
• What is simplex redundancy?
  It provides a single backup communication path for critical connections, allowing the system to maintain operation if the primary network link fails.
• What is the fiber port used for?
  The 100Base-FX port is used for long-distance connections or in environments with high electromagnetic interference where copper cables are unsuitable.
