Woodward 505DR Dual Redundant Turbine Controller Communication

Communication

The 505DR can communicate directly with the plant DCS and/or operator control panel using Modbus TCP or OPC communications.

Serial communication is also supported using RS-232 or RS-485 and ASCII or RTU Modbus.

Control PIDs can perform process control or be used as limiters for speed/load dynamics,

pumping/discharge pressures, cascade, auxiliary, intake plenum, exhaust plenum, and rotor acceleration.

System Protection

- Integrated overspeed protection logic and test functions

- First open indication on 15 shutdown inputs

- External alarm indication on 15 inputs

- Stuck at critical speed band logic

- Bufferless transfer between control modes and during Syscon switchover

- Operation and configuration password security
