The PLC 1756-EN3TR is a communication bridge module that is part of the PLC ControlLogix 2-port series of modules. Two 10-100 Mbps RJ-45 ports with embedded switches are included with this module. The controller supports up to 128 CIP motion axes (position loop) and up to 255 total axes, up to 128 TCP/IP connections and 256 Logix connections. Special features of the PLC 1756-EN3TR include embedded switch technology, communication rates of 10-100 Mbps, 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 maximum power consumption of the 1756-EN3TR is 5.1W and the power dissipation is 5.1W. It comes with a USB port. The 1756-EN3TR’s insulation voltage is 30 Volts continuous with an open enclosure and its operating temperature is 32-140o Fahrenheit. It has a current rating of 1.2 Amps, a thermal dissipation of 21.28 BTU per hour, and a power dissipation of 6.2 Watts. The power consumption is 5.1 Watts with a backplane current of 3 milliamps and 24 V DC and 1 amp at 5V DC. The 1756-EN3TR module supports EtherNet/IP connectivity and linear, star, and device-level ring (DLR) topologies. The module’s default configuration supports the linear and star topologies. The EtherNet/IP is an open industrial-networking standard protocol that supports real-time I/O message exchange. The EtherNet/IP network uses both off-the-shelf Ethernet communication chips and physical media for communication.
The 1756-EN3TR is an Ethernet Communication Module that is part of the ControlLogix Programmable Automation Controller (PAC) platform. This is an option module that is installed to any ControlLogix chassis whether it be a local or distributed I/O station. This module specifically functions as an Ethernet bridge module, connecting Ethernet capable processors, Remote I/O stations, Human Machine Interface (HMI), Supervisory Control and Data Acquisition (SCADA) system to a common network for implementing high-speed data exchange.
