4. Product Introduction (Anti-Template)
When a 3500 machinery protection rack must exchange real-time values and status with an EGD-compatible controller (such as a GE Mark VIe), the 3500/91 provides the dedicated gateway. It collects monitored values, setpoints, and status information from the rack and publishes them over Ethernet using the Ethernet Global Data protocol.
The module supports both producer and consumer exchanges, enabling bidirectional data flow suitable for closed-loop control applications. It occupies one full-height slot and works in conjunction with a 3500/22M Transient Data Interface module. Only one EGD gateway is permitted per rack. The associated I/O module determines whether the Ethernet connection is copper (10/100BASE-T) or fiber.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Confirm full model marking (3500/91), I/O module type (copper or fiber), revision labels, and connector condition. Photograph all identifiers.
- Live Rig Testing – Install in a compatible 3500 rack with a 3500/22M TDI, power up, verify Ethernet link, and confirm basic EGD communication and data exchange using Rack Configuration Software.
- QA & Anti-Static Packaging – After functional pass, protect the front-panel connectors and I/O module, clean the assembly, and seal in anti-static shielding with desiccant.
- Global Logistics & Export Compliance – Classify under the correct HS code for industrial communication modules. Packaging is rated for air and sea freight vibration; export documentation is prepared to minimize customs delays.
6. Technical Pitfalls & Integration Warnings
TDI Requirement – The 3500/91 will not function without a properly configured 3500/22M Transient Data Interface module running compatible firmware.
One Gateway per Rack – Installing more than one 3500/91 EGD module in the same rack is not supported and will cause configuration or communication conflicts.
I/O Module Matching – The main module must be paired with the correct I/O module (copper or fiber). Mismatched or missing I/O modules prevent network connectivity.
Software Version – Rack Configuration Software version 3.70 or higher is required. Older software versions cannot properly configure the EGD exchanges.
7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified 3500/91?
Stock units typically ship within 1–5 business days after verification. Air freight adds standard transit time.
What protocol does the 3500/91 use?
Ethernet Global Data (EGD) version 2.01 over Ethernet UDP/IP.
Does it require any other modules?
Yes. It requires a 3500/22M TDI module in the same rack and is limited to one EGD gateway per rack.
What Ethernet options are available?
10/100BASE-T (twisted-pair RJ-45) or 100BASE-FX fiber, depending on the I/O module ordered with the gateway.
Can it communicate with GE Mark VIe controllers?
Yes. It is specifically designed for integration with EGD-compatible controllers, including GE Mark VIe systems.
Is the 3500/91 the same as the system rack?
No. The 3500/91 is the EGD Communication Gateway module. The instrument rack is the 3500/05.
What software is used to configure it?
Bently Nevada 3500 Rack Configuration Software (version 3.70 or higher).
