The 2711-NM4 memory chip is a Series F EEPROM memory chip manufactured by Allen-Bradley. It is a 128K memory chip that is compatible with the Allen-Bradley PanelView 1200 series operator interface terminals. It is a PanelView accessory that is used as an upgrade to the PanelView 1200 terminals. The PanelView 1200 operator interface terminals are mostly used in different industries as an interface between the PLC system and the operators. The operators are able to monitor, configure, and program industrial processes with the terminals that are easy to use and support different languages. The 2711-NM4 memory chip is a programmable read-only memory and it is non-volatile in nature. It holds important instruction sets and firmware information that are needed by the terminals to operate. It is placed inside the expandable memory slot. This compact chipset should be handled carefully during installation. It has dimensions of 7 x 7 x 6 inches. This series is a revised edition upgrade chip.

The Allen-Bradley 2711-NM4 Series F EEPROM memory chip stores the applications of the operator terminal. The EEPROM memory can be burned by the operators by using an EEPROM burner that is able to accept a single dump of Intel Hex format data without using special commands. The operator interface terminal is equipped with network and communication ports using different network protocols. It supports the DeviceNet, ControlNet, DH+, and other common industrial protocols. The RS-232 serial port is used to connect the operator terminal with a personal computer. The 2711-NM4 memory chip can take up to 40 seconds to program a large application file. After programming the memory chip, it is advised to wait for 1 minute before using the terminal.
