VE4014 Emerson DeltaV Series 2 Module Datasheet & Manual

Emerson VE4014 DeltaV Series 2 Profibus DP Interface Card

Configured for fieldbus network integration in Emerson DeltaV Series 2 platforms, the Emerson VE4014 (VE4014 Profibus DP Interface Card) provides direct physical/electrical execution. This module establishes real-time cyclic and acyclic data mapping pathways between the host controller and remote I/O blocks, variable frequency drives, or field sensors operating on the Profibus DP network topology.

Hardware Specifications

FOUNDATION Fieldbus / Profibus PA Connectivity and Noise Suppression

The card features integrated field-to-system galvanic isolation barriers to structurally isolate the internal LocalBus communication processors from external electrical transmission lines. When field network cabling passes adjacent to 4-20 mA HART loop protocol lines or high-voltage AC motor conductors, the internal differential filtering circuitry attenuates common-mode electrical noise and high-frequency inductive cross-talk. This physical layer separation preserves RS-485 bit-stream timing tolerances across long trunk segments.

Frequently Asked Questions

Q: How does the VE4014 handle redundancy switchover timing during an active fieldbus communication failure?

A: When configured in a redundant pair on a compatible carrier, the standby VE4014 continuously tracks the active node states via the backplane layer. Upon detection of a physical frame timeout or internal hardware error, the card executes an automatic bumpless switchover to the backup card without losing slave device registration codes.

Q: What are the electrical constraints when executing a hot-swap under power?

A: The VE4014 is engineered for full hot-swap online insertion and extraction. The physical connector pins are staggered to align ground and logic lines in sequence, which controls transient electrical inrush and prevents voltage sags that would disrupt adjacent running cards on the Series 2 carrier.

Field Installation Guidelines

• Module Insertion and Carrier Earthing: Push the interface card firmly into its designated carrier slot until the mechanical locking ears click home. The carrier rail must bond directly to the plant copper instrument earth grid with an electrical impedance below 1 Ohm to ensure effective high-frequency noise redirection.
• Profibus Network Shielding: Connect the overall shield of the Profibus DP cable directly to the metal shroud of the DB9 terminal connector. Ensure that the network cable drain wire terminates to the plant instrument ground grid at the marshaling cabinet enclosure side only to prevent structural ground loop currents.
• Segment Termination Requirements: Apply standard active RS-485 termination parameters at both physical ends of the Profibus DP trunk line. If the VE4014 is placed as the final physical device on a segment, ensure the termination switch on the terminal block connector is moved to the "ON" position.
