How to Replace a DH+ PanelView with PanelView Plus 7 (Keep Your SLC 5/04)

When you need to replace DH+ PanelView Standard operator terminals (such as a PanelView 550, 600, 1000, or 1400 on Data Highway Plus) that fail on the plant floor, maintenance teams face an immediate challenge. Modern replacement operator terminals from Rockwell Automation, including the PanelView Plus 6 and PanelView Plus 7, operate exclusively over standard EtherNet/IP networks and lack native DH+ ports.

System integrators frequently recommend replacing the entire control rack with a CompactLogix or ControlLogix system—resulting in tens of thousands of dollars in hardware costs, ladder logic rewrites, and prolonged downtime.

The smart solution is to replace DH+ PanelView terminals with modern Ethernet PanelView Plus units while keeping your reliable SLC 5/04 and PLC-5 controllers intact using the ANC-100e gateway.

The Communication Challenge: EtherNet/IP PanelView to DH+ Controllers

Legacy PanelView terminals communicated directly over Allen-Bradley Blue Hose cables using proprietary DH+ protocols. Modern PanelView Plus terminals run FactoryTalk View Machine Edition (ME) and utilize Ethernet communication drivers.

The ANC-100e functions as a transparent communications bridge. It translates modern EtherNet/IP CIP messaging into native DH+ packets, enabling seamless read/write data exchange directly with your existing SLC 5/04 and PLC-5 data tables (such as N7:0, B3:0, and F8:0).

Why Choose ANC-100e to Replace DH+ PanelView Hardware?

While alternative gateways exist, the ANC-100e is engineered specifically to eliminate configuration hurdles during HMI retrofits:

• No Special SLC 5/04 Restrictions: Unlike competing gateways (such as ProSoft AN-X2, which lists documented restrictions when communicating with SLC 5/04 over DH+), the ANC-100e supports full, unrestricted EtherNet/IP communication to both SLC 5/04 and PLC-5 processors.
• No Complex Tag-Mapping Schedules: Unlike RTA data-mapping gateways that require building hundreds of tag mapping lines in software, the ANC-100e utilizes standard ControlLogix routing architecture natively in FactoryTalk Linx.
• Plug-and-Play DH+ Auto-Detection: The ANC-100e automatically detects DH+ network baud rate (57.6k, 115.2k, 230.4k), identifies Blue/Clear wire polarity, and claims a free DH+ node address automatically.
• Extreme Industrial Temperature Range: Rated from -40°C to +85°C, ensuring reliable 24/7 operation in harsh plant floor control cabinets where standard gateways fail.
• Compact Form Factor: Pocket-sized design mounts easily on existing cabinet DIN rails alongside the new HMI power supply.

Step-by-Step Retrofit: Upgrading to PanelView Plus 7

Following this simple migration procedure allows plants to complete an HMI replacement in a single maintenance shift:

1. Convert the HMI Application: Open the legacy PanelBuilder32 (.PBA/.PBD) application file in FactoryTalk View Studio Machine Edition to convert graphics and tags into a modern .MED application.
2. Configure Communication Routing: In FactoryTalk Linx, add an Ethernet path targeting the ANC-100e IP address, specifying the target DH+ node address of your SLC 5/04 or PLC-5 processor.
3. Install Hardware: Mount the PanelView Plus 7 in the cabinet door cutout and connect an Ethernet patch cable to the ANC-100e.
4. Connect Existing DH+ Cable: Plug your existing 3-pin Phoenix connector or Blue Hose cable into the ANC-100e DH+ port.
5. Power Up & Run: The ANC-100e auto-senses network parameters immediately, establishing real-time communication between the new PanelView Plus and the legacy PLC.

Summary: A Practical Strategy to Replace DH+ PanelView Units

Modernizing human-machine interfaces does not require abandoning dependable PLC-5 and SLC 5/04 hardware. By using the ANC-100e as a dedicated Ethernet-to-DH+ bridge, automation engineers achieve state-of-the-art PanelView Plus visualization while protecting their capital investment and avoiding costly plant shutdowns.
