The 1756-EN2TR is a logic communication module from the 1756 ControlLogix series. This module has been created by Allen-Bradley to fulfill any compatible applications. This module is used mainly to establish communication links between different devices. It can be used to connect controllers to local and remote I/O modules, message modules, and to controllers with access with several types of software, among others. The Allen-Bradley 1756-EN2TR logic communication module works basically as an Ethernet or IP network, providing an Ethernet and IP bridge with an embedded switch and copper supports. It also provides motion of eight axes. This module not only connects modules and drives, but it acts as an adapter for remote links, a communication devices with other Ethernet and IP devices, and as a bridge to route messages and signal to other devices or networks.

The 1756-EN2TR features two Ethernet RJ45 Category 5 ports and one USB 1.1, full speed (12 Mbps) port. The cables used can be shielded or unshielded, depending on the preferences of the users. The Allen-Bradley 1756-EN2TR logic communication module supports linear topologies and device level ring (DLR) topologies. It features 128 TCP and 256 CIP connections. This module has a current draw of 1 Amp at 5.1 Volts DC, a power dissipation of 5.1 Watts, and an isolation voltage of 30 Volts. This module can operate at specific ranges of environmental conditions like an operating temperature of 0 to 60 degrees Celsius, an ambient temperature in the surrounding air of 60 degrees Celsius and a relative humidity of 5 to 95% without condensing.

The 1756-EN2TR communication module is an Ethernet industrial communication module from the Allen-Bradley ControlLogix series. It features 1 USB port and 2 RJ45 ports. The 1756-EN2TR Ethernet communication module can be installed in any slot in a ControlLogix chassis and it can be programmed with either the Studio 5000 Logix Designer software or the RSLogix 5000 software. This communication module is a piece of open-type equipment that does not have an enclosure, so it should not be exposed to water, dust, debris, or chemicals or used in hazardous or polluted industrial locations without the proper type of additional protection. When it operates, the 1756-EN2TR Ethernet communication module dissipates 5.1 Watts of energy as power and 21.3 BTU per hour of energy as heat.


The Allen-Bradley 1756-EN2TR Ethernet communication module can communicate at speeds of 10 Mbps to 100 Mbps over the Ethernet network. Its operating temperature range is from 32 to 140 degrees Fahrenheit or 0 to 60 degrees Celsius. The 1756-EN2TR Ethernet communication module can support both general messaging and real-time messaging. Additionally, it can also support the simultaneous transferring of critical diagnostics information and of safety and control data. The 1756-EN2TR Ethernet communication module does not need a routing table to store information. It does not need adapters in most situations because it is able to connect directly to workstations and computers through its built-in ports. The 1756-EN2TR Ethernet communication module uses Category 5 and Category 6 cables as its communication cables. It can be used as part of a redundant Ethernet network setup.

The Allen-Bradley 1756-EN2TR Ethernet communication module is manufactured in the ControlLogix module series. Its rated communication speeds on the Ethernet network are 10 to 100 Mbps.
