Emerson VE4006P2 M-Series Serial Interface Card

Configured for serial data acquisition and integration in DeltaV control networks, the Emerson VE4006P2 (VE4006P2 Serial Interface Card) provides direct physical/electrical execution of multi-protocol serial communication across dual independent ports.

Hardware Specifications

Process Control: Serial Interface Connectivity

The VE4006P2 supports high-density integration with up to 32 data sets (16 per port), enabling seamless interoperability between legacy field devices and the DeltaV control architecture. Each port is physically isolated from the system backplane and from the opposing serial port to prevent common-mode noise propagation. The card supports selectable RS232, RS422/485 half-duplex, and RS422/485 full-duplex transmission modes, providing flexibility for diverse physical layer requirements. The module handles configurable parity (Even, Odd, None) and provides deterministic data polling across a wide spectrum of baud rates, ensuring stable communication performance in high-EMI environments.

Frequently Asked Questions (FAQ)

Q: Are the serial ports on the VE4006P2 internally grounded?

A: No. Each port is isolated from the system and the opposing port, requiring external chassis or signal grounding to maintain the isolation integrity and prevent electrical noise accumulation on the serial lines.

Q: Can the dual ports be used for redundant communications to the same device?

A: Yes. The dual-port architecture allows for redundant serial path configuration. When configured for redundancy, the controller manages the communication switch-over between ports without data loss, provided the external field cabling supports the redundant topology.

Field Installation Guidelines

• Mounting: The VE4006P2 module must be installed on a DeltaV M-series I/O carrier. Ensure the simplex terminal block is seated securely to maintain the signal ground connection.

• Wiring: Utilize shielded twisted pair cables for RS422/485 applications. The shield must be terminated at the designated grounding lug on the carrier to minimize protocol conversion latencies and induced interference.

• Grounding: External grounding of each port is required. Establish a low-impedance path to the cabinet common ground bus to protect the internal isolation barriers from transient voltage surges.

• Configuration: Verify that baud rate and parity settings in the DeltaV workstation match the connected field device requirements before initiating communication to prevent framing errors or packet corruption.
