Description
PANELVIEW PLUS 400
Grayscale keypad operation.
Allen-Bradley 2711P-K4M20D is a DC-powered PanelView Plus 400 keypad terminal with a grayscale display. The 3.8-inch screen provides a 320 × 240 pixel workspace for the configured machine interface. Its network base includes Ethernet and RS-232 connections. The keypad supports numeric entry and application navigation through physical controls. Removable CompactFlash storage assists with application and maintenance file handling. This original-generation configuration must be matched to the installed project and is distinct from later Plus 6 color terminals.

Operator Interface & Connectivity
01 / Present the machine application
The grayscale display shows the process values, alarm information and control objects defined in the loaded Machine Edition runtime.
02 / Accept physical-key commands
Numeric and navigation keys provide a deliberate operator-entry method, while function-key behavior is assigned by the application.
03 / Connect the configured controller
Ethernet carries the selected network driver traffic while the separate RS-232 port supports its configured serial role.
RUNTIME→KEYPAD / DISPLAY→CONTROLLER
05
Runtime & Replacement Planning
Retain the original runtime generation
Application compatibility depends on the installed terminal firmware and the saved runtime version. A similar faceplate does not establish an interchangeable configuration.
Record the terminal series before deciding which application-memory limit applies.
A
Power and panel replacement
This configuration uses DC power. Check the terminal power connector and enclosure arrangement before replacement.
B
Communication planning
Preserve the network address, controller path and any fitted communication module.

Our Company History
2005
The Beginning
Company was founded in Xiamen, Fujian, China, in 2005 with a team of only four people. At that time, we mainly served selected European and North American markets, supplying commonly requested industrial automation products from Siemens, Allen-Bradley and Bently Nevada. Although the business was still developing and we completed relatively few orders, this period helped us build essential product knowledge and international trade experience.
2017
A Period of Growth
By 2017, our team had grown to approximately 30 people, and we had established a warehouse for in-stock automation components. Our business expanded across Europe, North America and Southeast Asia, while our product range grew from popular models to scarce and discontinued industrial automation parts. As our product knowledge and service experience increased, we completed nearly 20 orders per month on average.
