2711-NM28 Allen Bradley 8MB flash ATA card

This module supports transmission speed of 125k bit/s, 250k bit/s, and 500k bit/s using Allen-Bradley DeviceNet cable. This utilizes Common Industrial Protocol (CIP) as the main communication backbone and partners to partner to an existing DeviceNet scanner module in the network. This adapter responds to the request of the Scanner such as 1769-SDN to provide the requested data.

This communication module may be used to interface and send messages to controllers belonging to the 1769 platform. It is also capable of responding to DeviceNet scanners of other Programmable Logic Controller (PLC) product family such as PLC5, SLC500 and ControLogix. This is achieved with the utilization of the supported messaging functions.

This adapter may be installed beside any 1769 Compact I/O module. However, the Power Supply Distance rating must be met which is 4. This means that the module cannot be installed more than Frou (4) modules away from the power supply. When used with a MircoLogix 1500, the modules is installed beside the base unit or to an adjacent module.

Typical problems arise when the 1769-AND is not properly installed especially to a 1769 CompactLogix assembly. When installing the 1769-ADN adapter to a CompactLogix system, the bus connectors must be securely locked to establish an electrical connection. If resistance is felt when securing the module, disengage the module and inspect if the PIN connectors are properly aligned before proceeding again with the connection.
