Allen Bradley - HMI

Panelview 550

The Allen Bradley PanelView 550 is a series of terminals that provide engineers and technicians with a graphical user interface to interact with automation processes to monitor and control. The PanelView 550 series of terminals come with various screen sizes ranging from 3.5 inches up to 15.1 inches. The PanelView 550 series terminals can either be equipped with touchscreens, a keypad control system that offers up to 40 function keys, or a combination of both. Depending on the configuration and model of the HMI terminal, the terminal can have a minimum of 256 MB of RAM and a maximum of 512 MB of RAM. The storage memory of the PanelView 550 terminals is also a minimum of 256 MB and a maximum of 512 MB, and it can be expanded by using compatible SD cards. Most PanelView 550 series terminals come with Ethernet and RS-232 ports for network connectivity along with USB ports for data transfer and external device connectivity. These terminals operate on 24 volts DC nominal or 240 volts AC depending on the model type. Users can also select the conformal coating configuration of most of the models in the PanelView 550 series. The conformal coating provides extra protection to the internal circuitry of the terminal protecting it against harsh conditions such as moisture. When installing a new terminal, make sure to isolate it from the mains to avoid any injuries. For help with installing this series of terminals, as well as dealing with any troubleshooting, please refer to the manual.

PanelView 550 Selection Guide

Allen Bradley's PanelView 550, sometimes denoted as PV550, terminal family is a line of high-performance terminals. With a space-saving design and a flat-screen display, these PanelView 550 high-performance monochrome operator terminals are developed to serve the needs of users. These low-cost terminals with a compact design are packed with performance features.

In this guide, we will go over some of the most important features of PanelView 550 terminals to help you decide which one is best for your application.

Hardware Specifications

Display

All PanelView Terminals come with a display with mono LCD technology that delivers high reliability. This display comes with a blue mode. The area (width x height) of the LCD or touch screen that can be used for touching or viewing is 120 millimeters x 60 millimeters. The resolution of these mono displays is 256 x 128.

In these terminals, Backlight is installed in displays. These backlights are based on light-emitting diodes (LED) technology. The user experience is enhanced and improved with LED backlight technology, which delivers great illumination consistency. The backlighting's internal structure and positioning enable it to spread light more properly throughout the screen, resulting in high-definition readability. The estimated life expectancy of the backlight is about 100,000 hours.

Real-time Clock

The PanelView 550 operator terminals are equipped with a real-time clock (RTC). The critical timestamps are all generated by this internal clock.

A lithium battery is contained in the real-time clock (RTC) module and is exclusively in use by the RTC. The battery isn't needed to keep track of input or backup applications. This module has a seven-year average life span.

In these terminals, RTC can be replaced. You must make a backup of the application that is currently running. Otherwise, after the RTC is changed, the application would become inoperable.

Operator Input

PanelView 550 terminals offer flexibility to choose a terminal from this series with only a keypad or touchscreen, or both as an operator input.

All PV 550 terminals from the 2711-B5A catalog have both keypad and touch. PV 550 terminals that belong to the 2711-K5A catalog have only a keypad option. Only a touchscreen is available on PV 550 terminals from the 2711-T5A catalog.

The touch screen consists of 128 cells arranged into 16 columns and 8 rows. Each touch cell comes with a size of 16 pixels x 16 pixels. These terminals come with a keypad in which stainless steel dome on the membrane keypad is present on the conducting portion of the printed circuit board. There are ten functional keys on the Keypad (F1 to F10). These function keys on keypad terminals are used to activate functionalities on the terminal display. Customized legends could be present on these keys. You can use the function keys as well as touchpad objects on keypad and touch screen terminals to activate functions.

Along with functional keys, there are four cursor keys on the keypad. Along with function and cursor keys, there are also 14 numeric keys present on the keypad, including numeric value keys (0 to 9), a negative value key (-), a decimal point key (.), a clear/cancel key (←), and a store key (↵).

LED Indicators

PanelView 550 operator terminals have two embedded LED indicators. One is a green LED that indicates communication status and is known as the COMM status indicator. The red LED, which is commonly referred to as the FAULT status indicator, is used to recognize firmware and hardware failures.
