5X00300G02 Ovation DCS Fieldbus Communication Card

Description

Product Overview

The Emerson Ovation 5X00300G02 is a Profibus-DP communication interface module built for the Ovation distributed control system. It creates a bridge between the Ovation controller backplane and Profibus-DP fieldbus networks, enabling real-time bidirectional data exchange with remote I/O racks, variable speed drives, valve positioners and intelligent field instruments. It supports high-speed cyclic process data and device diagnostics, commonly deployed in power generation, pulp & paper and chemical process plants. OEM production has ended; available stock consists of surplus or refurbished tested replacement units for Ovation control racks.

Technical Specifications

Engineer Notes

• This is a fully integrated communication module; no separate personality card required. Hot-swap can be performed when site lockout/tagout procedures are followed.
• Front panel LEDs indicate module health, backplane link status and Profibus-DP bus activity. Bus faults, slave device dropouts and communication timeouts are reported to the Ovation controller.
• Terminate the Profibus-DP bus correctly at both physical ends of the network. Missing or duplicate bus termination is the leading cause of intermittent communication drops.
• Use shielded Profibus DP cable for fieldbus wiring. Separate fieldbus cables from high-current AC power and relay wiring to reduce electrical interference.
• Configure slave device addresses, cyclic data mapping and watchdog timers in the Ovation system database before commissioning.
• Apply ESD controls while handling. De-energize rack power before module removal or insertion if hot swap is not approved. After replacement, verify bus scan, slave device detection and real-time data transfer.

Pre-Shipment Test Protocol

1. Visual inspection: Check PCB, edge connector, front panel LEDs, Profibus terminal connector and housing for bent pins, corrosion or component damage.
2. Continuity and isolation test: Verify 500VAC isolation between Profibus field circuit and Ovation backplane circuits.
3. Functional bench test: Install the module in Ovation rack, connect to Profibus-DP slave simulators, scan bus and confirm all configured slave devices are detected. Validate cyclic read/write data exchange.
4. Fault simulation: Disconnect bus cable and remove slave devices; confirm module reports bus faults to Ovation controller.
5. Power cycling: Cycle 24VDC rack power 10 times, confirm module re-establishes Profibus communication after each restart.
6. Save test logs and photos for QA records.

Buyer FAQ

Q: Can I swap 5X00300G02 directly with other Ovation communication modules? A: Physical form fits the same rack slot, but firmware and bus protocol differ. Confirm controller firmware version, database configuration and bus topology before cutover.

Q: Does this module support redundant Profibus-DP bus operation? A: Redundancy depends on system configuration, slave devices and bus wiring. Check plant control drawings for redundant bus requirements.

Q: Is this new original Emerson factory stock? A: OEM production has stopped. Available units are surplus or fully refurbished tested stock. We offer a 12-month warranty on tested units.

Q: Are Profibus bus cables or terminators included? A: Bus cable and terminators are not included unless explicitly noted on your quote. Confirm these accessories at order placement.
