【英文介绍】

The Allen-Bradley 1756-EN3TR is a communication bridge module that is part of the Allen-Bradley ControlLogix 2-port series of modules. The module contains two 10-100 Mbps RJ-45 ports with embedded switches. The controller supports up to 128 CIP motion axes (position loops) and up to 255 total axes, up to 128 TCP/IP connections and 256 Logix connections. Special features of the Allen-Bradley 1756-EN3TR include embedded switch technology, 10-100 Mbps communication rates, 128 CIP motion axes, 128 TCP/IP connections, and 256 Logix connections. Its backplane current (mA) is 1A at 5.1V DC and 3mA at 24V DC. The 1756-EN3TR has a maximum power consumption of 5.1W and a power consumption of 5.1W. It comes with a USB port. The 1756-EN3TR ™ has an insulation voltage of 30 volts continuous, an open housing, and an operating temperature of 32-140 degrees Fahrenheit. It has a current rating of 1.2 amps, a heat dissipation of 21.28 BTU per hour, and a power consumption of 6.2 watts. Power consumption is 5.1 watts, and backplane currents are 3 mA, 24 V DC, and 1 amp (5V DC). The 1756-EN3TR module supports EtherNet/IP connectivity and linear, star, and device-level ring network (DLR) topologies. The module's ™ default configuration supports linear and star topologies. EtherNet/IP is an open industrial networking standard protocol that supports real-time I/O message exchange. EtherNet/IP networks use off-the-shelf Ethernet communication chips to communicate with physical media.

The 1756-EN3TR is an Ethernet communication module that is part of the ControlLogix Programmable Automation Controller (PAC) platform. This is an optional module that can be installed on any ControlLogix chassis, whether it is a local or distributed I/O station. Specifically designed as an Ethernet bridge module, the module connects Ethernet-enabled processors, remote I/O stations, human machine interface (HMI), monitoring and Data acquisition (SCADA) systems to a public network for high-speed data exchange.

The 1756-EN3TR feature supports both linear and device-level ring network (DLR) topologies, where linear is the smallest and simplest network connection where a single run of Cat5 or Cat6 physical media is used to implement an Ethernet network. It does not provide a certain degree of redundancy, whereas the device level ring network (DLR) provides high availability and redundancy.

The 1756-EN3TR supports up to 128 TCP connections, 256 Common Industrial Protocol (CIP) connections, 128 backplane and 128 Ethernet CIP unconnected messages. These connections can be made via the integrated two (2) RJ45 Ethernet interfaces installed on the module. The module supports transfer speeds of 10/100 Mbps with a maximum coverage distance of 100 meters and can be extended by installing an Ethernet switch or fiber optic media converter.

The 1756-EN3TR is powered by a backplane with a current consumption of 1 amp @ 5.1 volts DC and 3 MA @ 24 volts DC, a power consumption of 5.1 watts and a heat dissipation of 17.4 British thermal units (BTU) per hour.
