Choosing between an operator touchscreen and a logic controller can stall a control panel project before it starts. The Allen Bradley PanelView Plus 7 Ser B Industrial HMI Touchscreen 2711P-T12W21D8S and the Automation Direct D2-260 Programmable Logic Controller CPU sit at two very different points in that decision and at two very different listed prices. This head-to-head sorts out what each component does best so you can pick the right one for your setup.
Quick verdict
If your missing piece is a color touchscreen operators can interact with, the PanelView Plus 7 is the component to look at. If your missing piece is the processing brain-the CPU with memory, PID loops, and Modbus commands-the D2-260 is the component to build around and the lower-cost way to get it.

Where each product wins
The PanelView Plus 7 wins when the job is presenting machine data to a person. It is a Touch Panel with a color display, which is the core of an HMI. The D2-260 wins when the job is running control logic. It has a 30.4K-word total internal memory, a ladder memory framework, user data memory, support for up to 16 PID loops, and over 280 instructions-so it handles the real-time control work.
Allen Bradley PanelView Plus 7 Ser B Industrial HMI Touchscreen 2711P-T12W21D8S
The PanelView Plus 7 is the right pick when the operator interface is the whole point of the purchase. It is a Touch Panel with a Color Display, and the 2711P-T12W21D8S model carries the PanelView Plus 7 series design with a 2018 year of manufacture. The listed price of USD 799.99 puts it at the higher end of this comparison. The trade-off is condition: this is a used unit with visible scratches and scuffs on the screen surface, and the bezel shows cosmetic wear. For a display that operators will look at directly, those blemishes are the main thing to accept. Choose it for the complete HMI touchscreen package; just be ready for the cosmetic wear.
Automation Direct D2-260 Programmable Logic Controller CPU
The D2-260 takes the opposite route: no screen, just control logic. This used PLC CPU module is built around a 30.4K-word total internal memory, with a 15.8K-word ladder memory framework and 14.6K words of user data memory. It supports up to 16 independent PID loops, more than 280 RLL/IBox instructions, and native ASCII IN/OUT data strings plus expanded Modbus network commands. The listed price is USD 130.00, making it the far less expensive component here. The limitation is that a CPU alone is not a complete control panel; you are integrating a processor, not mounting a display. If your application needs logic and communications depth without a screen, this is a strong, low-cost core to build around.
Final choice by use case
- Choose the Automation Direct D2-260 when you need a logic-processing CPU with deep memory, PID loop support, and Modbus command expansion. It is the functional heart of a control system.
- Choose the Allen Bradley PanelView Plus 7 when you need a color touchscreen operator interface and are willing to accept a used screen with surface wear.
