1、 Summary of Model Information
Complete order model: 3500/91-02-00
Hardware body part number: 190782-01
Module abbreviation: 3500/91M (commonly abbreviated as 3500/91 in the industry)
Structural features: Integrated module, no independent separated rear I/O card, Ethernet interface directly integrated into the module backplane
2、 Core functional positioning
Exclusive Protocol: EGD (Ethernet Global Data V2.01)
Used for high-speed real-time data exchange between 3500 rack and GE Mark VIe turbine control system;
Relying on UDP/IP Ethernet to achieve producer/consumer data exchange.
Transmission Content
All steady-state measurement values, alarm status, module diagnostic information, alarm suppression/reset instructions of the rack;
⚠️ Does not support transmission of vibration waveforms, spectra, and axis trajectories; It also does not support Modbus protocol.
Supplementing the differentiation of the three major communication cards (the top priority in procurement)
Can typical module protocol docking systems transmit waveforms
3500/91M EGD protocol GE Mark VIe ❌ Only steady-state values
3500/92 Modbus TCP/RTU Universal DCS/PLC ❌ Only steady-state values
3500/22M (TDI) Bently proprietary TDI protocol System1 diagnostic software ✅ Waveform, spectrum, transient recording
Engineering standard matching:
Connect GE Mark VIe → select 3500/91M
Ordinary third-party DCS (Siemens/Emerson, etc.) → Choose 3500/92
Vibration fault analysis and waveform recording are required → 3500/22M must be configured
3、 Key hardware parameters
Network interface: RJ45 10/100Base TX adaptive Ethernet
Communication protocol: EGD v2.01, UDP/IP
Power consumption: Typical 7.4W, powered by the rack backplane
Appearance: 3500/05 rack standard full height card, supports hot swapping
Indicator lights: OK (module normal), COMM (network communication)
Working environment: -30 ℃~+65 ℃, 5%~95% RH, no condensation
4、 Lifecycle information
Continuous supply from the original factory; Both brand new original equipment and disassembled spare parts are in circulation in the market
Warranty reference: Brand new original 12 months, disassembled spare parts 3-6 months
5、 Typical application scenarios
Thermal power/gas turbine project, data exchange between 3500 TSI protection rack and GE Mark VIe unit control system;
Mostly used for integrated monitoring solutions of large steam turbine generator units.
