How to Connect EtherNet/IP PanelView Plus 6 & 7 to PLC-5 and SLC 5/04 on DH+

Industrial facilities face a common modern migration challenge: legacy PanelView Standard (DH+) terminals are obsolete and failing, yet the underlying Allen-Bradley PLC-5 and SLC 5/04 controllers operating on Data Highway Plus (DH+) continue to perform reliably.

Replacing legacy operator interfaces with modern PanelView Plus 6 or 7 terminals is straightforward on the HMI side, but newer terminals only provide EtherNet/IP ports. Rather than executing costly processor upgrades or installing expensive ControlLogix chassis bridges, plant engineers can bridge modern Ethernet HMIs directly to legacy DH+ nodes using the ANC-100e gateway.

The Migration Challenge: Ethernet HMIs on Legacy DH+ Networks

When a legacy PanelView 550, 600, 1000, or 1400 on DH+ fails, finding working surplus hardware is both costly and unreliable. Modernizing to a PanelView Plus 6 or 7 offers enhanced visualization and hardware support, but introduces a media and protocol barrier:

• Physical Layer Mismatch: PanelView Plus models feature RJ45 Ethernet ports, while legacy controllers operate on 3-conductor Belden 9463 Blue Hose.
• Protocol Routing Requirements: FactoryTalk View ME communicates using CIP / EtherNet/IP encapsulation, whereas PLC-5 and SLC 5/04 processors respond to PCCC commands over DH+.
• ControlLogix Chassis Overhead: The traditional Rockwell solution requires a multi-slot 1756 rack, power supply, 1756-ENBT bridge, and 1756-DHRIO module—often exceeding $4,000 in hardware and cabinet space.

The Solution: ANC-100e Built-In "HMI Lines" Feature

The ANC-100e Ethernet to DH+ Converter includes a dedicated HMI Lines routing feature engineered specifically for Ethernet-based HMI migrations.

• Up to 5 Concurrent HMI Connections: The ANC-100e supports up to 5 independent HMI Lines, allowing multiple PanelView Plus terminals or SCADA client sessions to poll different DH+ PLC targets simultaneously.
• Zero Ladder Logic Modifications: The PLC-5 or SLC 5/04 processor does not require code edits or memory map adjustments; data tables remain identical.
• Native ControlLogix CIP Emulation: FactoryTalk View Studio configures communication paths using standard ControlLogix Ethernet drivers, eliminating proprietary driver software.
• Auto-Baud & Auto-Polarity: Automatically synchronizes to existing DH+ network baud rates (57.6k, 115.2k, 230.4k) and corrects wiring polarity at power-up.

Step-by-Step Architecture & Configuration Overview

1. Connect Physical Wiring: Connect the plant Ethernet switch (or PanelView directly) to the ANC-100e RJ45 port. Connect the DH+ 3-pin Phoenix connector to the Belden 9463 network or use the supplied 8-pin mini-DIN cable for direct connection to the processor.
2. Access ANC-100e Web GUI: Open a standard web browser and enter the ANC-100e default IP address. Navigate to the HMI Lines configuration tab.
3. Map Destination DH+ Octal Nodes: Assign HMI Line targets by mapping the destination DH+ octal node address of each target PLC-5 or SLC 5/04.
4. Configure FactoryTalk View Studio: In FactoryTalk View ME Communication Setup (RSLinx Enterprise / FactoryTalk Linx), point the device shortcut to the IP address of the ANC-100e using the standard Ethernet / ControlLogix routing path.
5. Deploy Runtime: Download the .mer runtime application to the PanelView Plus. Tags will immediately begin reading and writing to legacy data files (N7, B3, F8, etc.).
