Hardware Specifications
Display
PanelView 300 operator interface terminals have a monochrome (single color) display spanning 3 inches diagonally. It is a transflective liquid crystal display. It comes with light-emitting diodes for backlighting.
The presence of a transflective LCD makes it the best choice in applications where the installation of operator terminals is in surroundings with high ambient light, as well as direct sunlight.
This display offers a resolution of 128 x 64 pixels. The display can maintain its initial brightness up to 100,000 hours before its reduced to 50 percent of its factory brightness level.
The dimensions of the display measure 73 millimeters (width) by 42 millimeters (height).
Real-time Clock
PanelView 300 terminals come with a real-time clock. This clock offers real and precise timestamps information for numerous applications. A lithium battery is installed in this clock. This battery can power this clock for up to 7 years.
When the clock stopped working, you can replace it with ease. The 2711-NB4 is the supported real-time clock module by PanelView 300 terminals. This module comes with a lithium battery.
Operator Input
For PanelView 300 monochrome terminals, the operator input is the keypad. The operator has to press the relevant function key for screen objects.
The front of PanelView 300 terminals has a keypad along with the display. There are eight functions keys under the display (F1 to F8). These are functional keys that allow you to trigger operations on the terminal's display.
On the right side under the functions, there are four cursor keys. The up/down key moves the cursor upward and downward in the list. These keys also allow increment/decrement of values. The right/left key is used for the selection of the indicator bar, as well as to go into configuration mode.
A numeric keypad similar to a simple calculator is available on the left side. It has numeric keys (0 to 9), a decimal key, a negative sign key, a long arrow key for clearing/canceling, and a small arrow key for storage.
LED Indicators
There are two LED indicators, green and red, on the backside of the PanelView 300 terminal.
The green one is a COMM status indicator. If it is solid fill, then there is no communication fault. When the terminal will not be able to establish any communication, it will blink. In case of faulty communication, the LED will be off.
The red one indicates the fault in hardware /firmware. If it is solid, there is a fault either a restart or servicing is required. When it's blinking, then reloading of application software is required. If it is off, then the terminal is working fine.
These indicators make the detection of faults easy and efficient in your applications.
Weight
Each PanelView 300 terminal weighs around 673 grams or the equivalent of around 1.48 pounds.
Mounting and Cutout Dimensions
PanelView 300 terminal has the following dimensions: 7.76 inches x 5.53 inches x 3.21 inches (height x width x depth).
While mounting the PanelView 300 terminal, leave some space on the sides for the memory card and airflow. It is recommended to add 2.5 inches to the cut-out dimensions of the terminal to compute the installation space for the terminal.
Enclosure
To shield the internal circuitry of the PanelView 300 operator interface terminal, mount it either into an enclosure or a panel. When these terminals are mounted in a panel/enclosure, they can reach the NEMA type 12/13/4X rating.
Electrical Specifications
On the backside of PanelView 300 monochrome terminals, power connection terminals are present to connect the power supply.
These terminals require a direct current power source for their functioning. The supply should be able to provide a voltage of a minimum of 18 volts to a maximum of 32 volts. The supply should have a rated nominal voltage of 24 volts.
These terminals consume a maximum of 2.5 watts of power. If a nominal voltage of 24 volts is applied to the terminal, then the terminal will extract 0.105 amperes from the supply for its operation.
Integrated fuse, as well as the design of electronic circuitry in these terminals, provides protection against over-voltage as well as reverse polarity scenarios.
Communication Specifications
PanelView 300 operator terminal series supports the following communication protocols:
DH-485 Communication Protocol
There is a DH-485 communication port on the back of the PanelView 300 operator terminal.
This protocol allows connections to a single SLC controller for point-to-point transfer as well as multiple SLC controllers for network transfers over the DH-485 network. It provides communication with MicroLogix controllers as well.
There exists a DH-485 programming connector on the PanelView 300 operator terminal. It allows connections with a PC via an interface converter. It allows applications to transfer between terminal and PC.
RS-232 (DH-485) Communication
PanelView 300 operator terminal can have one RS-232 (DH-485) communication port.
This port allows point-to-point connection with Allen Bradley controllers SLC and MicroLogix/Compact Logix. It also provides a connectivity link via the AIC+ module with the MicroLogix controller.
If a computer is present on the DH+ link (Allen Bradley), then a connection can be made between the computer and this terminal's port via SLC 5/04 controller.
RS-232 (DF1) Communication
One RS-232/DF1 port is present on PanelView 300 RS-232 (DF1) terminals. This port not only allows connection with an RS-232 terminal port but a full-duplex communication with a wide range of controllers, including PLCs, SLCs, and Logix 5000 controllers.
To enable radio communication (modem) between the terminal and controller, this port is used.
DeviceNet Network Communication
PanelView 300 DeviceNet terminals connect devices using a DeviceNet connector on the DeviceNet network.
RS-232 Printer/File Transfer Port
This port allows for communication with a PC. This serial port, on a DeviceNet PanelView 300 terminal, allows applications transfer by making a connection with the PC on the RS-232 port of the PC.
It can also establish a connection with IBM printers for printing purposes. It is used to take prints of alarms and trigger messages. A selectable range of baud rates is available to communicate with the printer. You can set the rate to 1200 kilobits per second, 2400 kilobits per second, 9600 kilobits per second, 4800 kilobits per second, or 19200 kilobits per second.

Running Applications
PanelView 300 standard terminals offer the following processes that can be monitored or controlled while running applications.
Screen Security
Applications screens can be restricted or non-restricted. The application designer set the passwords for restricted screens.
These features allow only relevant personnel to access limited screens, thus keeping the system more secure and safe.
Bar Graph Displays
These are graphical visualization of variable values. Bar graphs can be displayed with or without scales and borders, as well as with several fill patterns.
Multistate Indicators
The state of a bit/value at a controller address is shown via multistate indicators. Multistate indicators can take on several forms. Furthermore, multistate indicators can have their inner text, filling template, or visual vary for each state (every state with different assigned attributes). Each indication can have a maximum of 2,000 states.
List Indicators
List indicators identify a list item based on the status of a bit/value at a controller address.
An indication list can have up to 255 entries. To show the state of an item, the list automatically scrolls.
Analog Gauges
The analog gauge displays a process variable like velocity, temp, or pressure using a spinning needle. A circular scale having tick marks, 1 to 4 needles, and a label featuring text/variable data comprise the gauge. The gauge's circular scale is an intrinsic element of it, although it may also be made separately.
Numeric Data Displays
Numeric Data Displays can be displayed both with and without accompanying text. Displayed data may get the following attributes depending on the specific application design: no fill, fixed-point, floating-point, no decimal point, varying field widths (number of digits), varied text sizes, and scaling.
Message Displays
Message displays include letters and numbers and are displayed when a controller triggers them. The message display could be of any length and cannot obstruct any other controls. Messages may have the following elements: alphanumeric text, visuals, variable date, time, and date.
Time or Date
Date and time info can be displayed as a stand-alone item or as part of a control/display object. A time and date can be shown with or without accompanying text and in multiple formats.
Printing
Printing can be done on terminals that include an RS-232 printer port. It prints triggered messages, triggered states, alarm messages, and an alarm list.
There are no formatting choices available when printing text. The application defines print properties for objects as well as alarms.
Printing tasks run in the background. During printing, the terminal continues to update and you can use it for other purposes.
Memory
For runtime environments, PanelView 300 standard terminals support 170 Kilobytes of memory to avoid any runtime errors. They also have 240 kilobytes of flash (nonvolatile) memory for attributes such as text, bitmaps, and application objects.
For applications files transfer and storage, PanelView 300 terminals make use of memory cards. These terminals come with a memory card slot.
PanelView 300 terminal's memory card retainer protects from electrical shocks. These shocks can be generated because the electrical enclosure has loose high-voltage wiring. It also offers electrostatic discharge protection for a maximum of 15 kilovolts.
For Application storage purposes, PanelView 300 terminals support the 2711-NM11 256K memory card, the 2711-NM13 2M flash memory card, the 2711-NM14 4M flash memory card, and the 2711-NM12 10M flash memory card.
