3、 Core role (in Mark VIe)
IONet real-time network exchange: connects UCS controllers (such as IS420UCSDH1A), I/O modules, and protection boards.
Redundancy and fault tolerance: support dual network/TMR the third mock examination redundancy and match Mark VIe controller redundancy architecture.
High speed real-time communication: ensuring reliable transmission of millisecond level control data, protection signals, and status information for gas turbines/steam turbines.
System expansion: Connect to the central control/data center through fiber optic ports, and connect to on-site I/O and HMI through electrical ports.
4、 Comparison
IS420ESWBH1A (GE): Network switch, Mark VIe system specific, responsible for controller I/O upper computer data exchange, not logic control.
8440-1831 (WOODWARD): Generator parallel controller, independently completes synchronization, load distribution, and protection.
HC800/PCD230 (ABB): DCS/excitation controller, responsible for process control, excitation regulation, and closed-loop operation.
