PanelView Plus 6 vs PanelView Plus 7

Overview

In industrial automation, the Human-Machine Interface (HMI) serves as the primary window into complex machinery. For over a decade, Allen-Bradley's PanelView Plus series has been the benchmark for visualization in systems powered by ControlLogix and CompactLogix controllers. However, as technologies evolve, legacy systems must inevitably yield to modern architectures.

The PanelView Plus 6 (PVP6), introduced in 2011, built upon the success of the original PanelView Plus platform by introducing Windows CE 6.0 and enhanced processing speeds. It became the workhorse of manufacturing lines globally. Today, the PVP6 is discontinued, classified by Rockwell Automation as "End of Life" (EOL) or "Obsolete."

Its successor, the PanelView Plus 7 (PVP7), represents a paradigm shift. Split into two distinct lines—Standard and Performance—the PVP7 streamlines hardware design, introduces widescreen aspect ratios, reinforces cybersecurity, and integrates native dual-port Ethernet for Device Level Ring (DLR) topologies. This guide provides a detailed technical comparison of these two hardware families to assist control engineers and system integrators in managing upgrades, understanding software compatibility, and executing seamless hardware migrations.

Performance & Capabilities

Hardware performance determines how responsive an operator interface is when handling dynamic graphics, trend logs, alarms, and animations. The PanelView Plus 6 processor architecture is based on an older ARMv6/v7 core running at slow clock rates (typically 512 MHz), which can result in sluggish boot cycles and delayed screen transitions when loaded with complex FactoryTalk View ME projects.

The PanelView Plus 7 represents a massive leap forward in raw computing hardware. Powered by faster, more modern processors (typically dual-core configurations running at 1.0 GHz or higher), the PVP7 dramatically reduces boot times (often by 50% or more compared to PVP6) and ensures instantaneous screen-capture buffering. Furthermore, the memory expansion (up to 1 GB RAM on PVP7 Performance Series B and up to 4 GB on Series C units) allows for much larger, data-heavy recipe storage, higher PDF documentation viewing resolutions, and lag-free trending charts.

Display resolutions have also undergone a much-needed modernization. The PVP6 relied exclusively on 4:3 aspect ratio SVGA or VGA screens. The PVP7 introduces modern widescreen aspect ratios (16:9), mirroring standard modern industrial screens. These high-brightness, high-contrast displays feature LED backlights with lifetimes exceeding 50,000 hours, lowering environmental power draw and improving operator visibility in low-light environments.

Programming & Software

Both families rely on Rockwell Automation’s FactoryTalk View Machine Edition (ME) software, but they support different version windows:

• PanelView Plus 6: Supports FactoryTalk View ME firmware versions 6.0 through 11.0. If you upgrade your design environment to FactoryTalk View ME v12, v13, or v14, you cannot compile a runtime file (.MER) compatible with a physical PanelView Plus 6 HMI unless you explicitly target v11.0 or lower.
• PanelView Plus 7: Supports FactoryTalk View ME firmware versions 8.0 through the latest current releases (v14).

Licensing and Runtime Limits

Developers must note the developer and runtime limitations built into the PanelView Plus 7 Standard series. Rockwell intentionally limited the PVP7 Standard to target smaller, stand-alone machine applications. The runtime limits are hardcoded:

1. Tag Limits: Maximum of 500 Controller Tags (directly referenced tags from the PLC).
2. Screen Limits: Maximum of 100 User Screens (including diagnostic and alarm screens).
3. Controller Connections: The Standard terminal can only connect to one controller directly (no capability to poll multiple logic engines on a plant network).

The PanelView Plus 7 Performance removes these arbitrary guidelines. It functions identically to the PanelView Plus 6 concerning capacity: infinite screen configurations, support for tens of thousands of controller tags, and concurrent communication to multiple Logix controllers across the subnet.

Communication & Networking

The core communications architecture is where these two families diverge the most.

The PanelView Plus 6 was designed in an era of transitional networking. It featured a modular chassis backplate where engineers could swap communication modules based on field requirements. This allowed the physical display to communicate across legacy media via specific modules:

• 2711P-RN6: DH-485 module
• 2711P-RN15S: ControlNet module
• 2711P-RN3: DeviceNet module

The PanelView Plus 7 does away with legacy network modules completely. There are no expansion slots on either the PVP7 Standard or Performance units. They are strictly Ethernet-native terminals.

For modern plants, this Ethernet focus is highly beneficial. The PanelView Plus 7 Performance comes equipped with an integrated Ethernet switch containing two RJ45 ports. This configuration natively supports Device Level Ring (DLR) topologies. In a DLR network, if a single Ethernet cable is severed, the network continues to route traffic in the opposite direction without dropping packet transmissions, ensuring uninterrupted operator monitoring.

If your retrofitted control architecture still utilizes legacy networks (such as blue-hose DH-485 or a DeviceNet trunk line), you cannot connect a PanelView Plus 7 directly. Instead, you must implement external network bridges, such as a 1783-NATR for network translations, or third-party gateways (e.g., HMS Anybus or ProSoft modules) to map legacy parameters to EtherNet/IP register objects.

Pricing & Lifecycle

The PanelView Plus 6 reached its End-of-Life (EOL) status several years ago. Rockwell Automation no longer manufactures these terminals, and official support is limited to "Silver Series" status (where repairs are attempted only if components remain in inventory). As a result:

• PVP6 Acquisition Costs: Sourcing spare PanelView Plus 6 terminals usually involves secondary markets, surplus inventory, or rebuilt components. Because they are in high demand for direct drop-in retrofits in regulated spaces, these legacy parts often command a price premium that exceeds the retail cost of a brand-new PanelView Plus 7.
• PVP7 Lifecycle: The PanelView Plus 7 is in its active production phase. It is widely supported, carries standard OEM warranties, and receives regular firmware updates addressing modern cybersecurity concerns (such as signed firmware validation and secure communications). Choosing the PVP7 prevents unplanned downtime caused by the sudden scarcity of obsolete spare parts.

When to Choose Each

Choose PanelView Plus 6 if:

• Absolute Code Validation is Required: In highly regulated environments (such as FDA-validated pharmaceutical facilities or explosive-rated petrochemical consoles), changing the touch-screen hardware can trigger massive re-validation documentation processes. Safe stockpiles of certified PVP6 units might be preferred to avoid these bureaucratic delays.
• Legacy Networks are Immutable: If the physical control architecture uses DH-485, DeviceNet, or ControlNet, and there is no budget to install Ethernet-capable PLCs or external gateway bridges, a direct, refurbished PanelView Plus 6 replacement remains the only cost-effective option.

Choose PanelView Plus 7 if:

• Implementing New Control Solutions: Any greenfield environment or panel-build must utilize the PanelView Plus 7 (or newer PanelView 5000 units) to guarantee compatibility with current PLC instruction sets and design tools.
• You Need Network Redundancy (DLR): Under high-availability scenarios where communications lines can fail due to physical stress, the dual-port DLR configuration on the PVP7 Performance is critical.
• Higher Resolutions are Desired: If operators need detailed high-resolution screens, widescreen graphics, or nested PDF schematics directly on the terminal, the PVP7’s crisp, widescreen, high-performance display panel is necessary.

1. Physical Panel Cutouts

One of the primary challenges when upgrading from PVP6 to PVP7 is that the physical panel cutouts are different. PVP7 terminals generally have more compact physical dimensions for the same display size due to thinner bezels and more integrated electronics.

To prevent engineers from having to cut or weld stainless steel doors on electrical enclosures, Rockwell Automation offers Bezel Adapter Kits. For instance:

• Upgrading an old 10-inch PVP6 to a 10-inch PVP7 requires an adapter plate (e.g., 2711P-RAAT10) to safely cover the oversized hole left behind by the older, bulkier unit and maintain the panel's NEMA rating.

2. Software Translation

Updating your software application includes the following process:

1. Retrieve File: Extract the application compiled runtime file (.MER) or original project folder (.MED) from the source PanelView Plus 6.
2. Restore Application: Open FactoryTalk View Studio ME on your engineering workstation and restore the runtime archive (.MED file restoration via application manager).
3. Adjust Resolution: If converting from a 4:3 display (PVP6) to a modern widescreen PVP7 (e.g., a 10-inch standard to 10-inch widescreen), execute the "Display Resolution" tool in FT View Studio. Scale original graphic elements to fit the new aspect ratios without stretching or truncation.
4. Target Compilation: Verify that tag references do not exceed 500 if compiling for a PVP7 Standard unit. Compile the new project as a newer runtime version matching your current PVP7 firmware target (typically v8.0 through v14.0).
5. Download: Download the compiled .MER file to the new PanelView Plus 7 via FactoryTalk Linx or transfer it directly using an SD card or USB flash drive.

Frequently Asked Questions

Q1: Can I load a PanelView Plus 6 .MER file directly into a PanelView Plus 7?

A: Generally, no. A runtime file compiled specifically for target operating systems below v8.0 will not execute directly on a PanelView Plus 7. You must open the original design project in Factorytalk View ME Studio version 8.0 or newer and compile a new runtime file targeting the exact firmware level running on your new PVP7 HMI.

Q2: Is there an easy way to communicate via DH-485 with a new PanelView Plus 7?

A: No native way exists since there are no expansion slots for network cards in the PVP7. To link a PVP7 to a network running on DH-485, you must install an external conversion trunk, such as a 1761-NET-AIC converter or a modern Ethernet-to-Serial/DH-485 gateway module.

Q3: What happens if my PanelView Plus 7 Standard runtime exceeds 500 tags?

A: If your design file exceeds 500 controller tags or 100 screens, the developer software will generate a critical compilation error, preventing you from deploying to a PVP7 Standard unit. If your application exceeds these boundaries, you must upgrade your hardware plan to a PanelView Plus 7 Performance terminal.
