When you're shopping for PLCs and HMIs, the first fork in the road is whether you need a standalone touchscreen for an existing controller or a single box that does both. The price gap is wide, but the right answer depends on what you're controlling and how much panel space you have. The Allen Bradley PanelView Plus 7 Ser B Industrial HMI Touchscreen 2711P-T12W21D8S is a large color HMI from the PanelView Plus family, while the PLC Controller Programmable Logic Controller 5" HMI Touch Screen For Industrial is an integrated unit that packs a controller and a touchscreen together.
Quick verdict
Choose the Allen Bradley PanelView Plus 7 if you already have a control system and want a large, color display to operate and monitor it. Choose the integrated PLC+HMI controller if you're building a compact machine and want logic, I/O, and a touchscreen in one unit without the cabinet space of a separate HMI. If your panel already uses PanelView Plus hardware, the Allen Bradley unit is the more direct expansion or replacement display.

Where each product wins
The Allen Bradley PanelView Plus 7 wins when screen size and a PanelView Plus form factor matter. It's a large panel with a Series B PanelView Plus 7 design and a 2018 manufacture date, so it gives you a much larger view of your process than the compact integrated unit. That makes it a better match for operator stations that need a sizeable interface.
The integrated PLC+HMI controller wins on simplicity and panel-space savings. Instead of coordinating a separate PLC and HMI, you get a single processor module with a built-in touchscreen, built-in I/O, and a 2-axis pulse output at 100KHz for stepper or servo applications. For small packaging, labeling, or positioning machines, that reduces wiring and simplifies the control cabinet.
Product notes
Allen Bradley PanelView Plus 7 Ser B Industrial HMI Touchscreen 2711P-T12W21D8S
This is a used Allen Bradley PanelView Plus 7 Series B touchscreen with a 12-inch color display and model number 2711P-T12W21D8S. The strongest reason to pick it is the large PanelView Plus 7 form factor, which gives you a sizeable operator interface for monitoring a machine or process. It also carries a 2018 manufacture date and comes from the United States. The limitation is the condition: the unit shows visible scratches and scuffs on the screen and wear on the bezel. You're working with used hardware, so inspect the touch surface and display response before integrating it into a production line.
PLC Controller Programmable Logic Controller 5" HMI Touch Screen For Industrial
This new integrated controller combines the HMI and the PLC in a compact package. It provides 9 inputs, 8 relay outputs, and a 2-axis pulse output at 100KHz for direct motion control, which is a practical fit for stepper or servo-based machines. The free HMI software and step-by-step video tutorials are useful when you're setting it up for the first time. The limitation is the display: at 5 inches, it's much smaller than the larger Allen Bradley, so you won't get the same at-a-glance overview of a complex process. It's best suited to simpler machines and local operator control.
Final choice by use case
If you need a large operator interface, the Allen Bradley PanelView Plus 7 Ser B gives you a large color touchscreen in a PanelView Plus 7 design. If you want a compact controller with a built-in display, the integrated PLC+HMI controller is the practical fit for small machines, servo/stepper positioning, and projects where panel space is tight. Before you decide, think of the touchscreen as either the operator window to a larger system or the entire control system itself.
