The 1756-EN2T is a communication module from the 1756 ControlLogix product line by Allen-Bradley/Rockwell Automation. The module is a copper EtherNet/IP bridge supporting up to 256 Logix connections. Like other modules from the ControlLogix family, this module also has a communication rate of 10/100 megabits per second and a 30 Volts (continuous) isolation voltage. Furthermore, the isolation voltage has the basic insulation type, Ethernet to Backplane/USB to Backplane/USB to Ethernet connections, and it is type-tested at 980 Volts AC for 60 seconds. In addition, the 1756-EN2T communication module has a 1.0 Amp current draw at 5.1 Volts DC and a power dissipation of 6.2 Watts. Also, the 1756-EN2T model has a thermal dissipation of 17.4 BTU per hour. This communication module with a single slot width can be found as part of the chassis and it does not require a special slot place.

The 1756-EN2T module is designed for and works perfectly with ControlLogix chassis and both standard and redundant power supplies. Chassis models that can be used with this communication module are the 1756-A4/A7/A10/A13 and –A17. In addition, the module has 1 RJ45 Category 5 Ethernet port and a USB 1.1 port with full speed at 12 megabits per second. The module does not have a rated enclosure since it is an open-type device, and its operating temperature range is 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit). The storage temperature of the module ranges from -40 to 85 degrees Celsius (-40 to 185 degrees Fahrenheit) and it operates in environments with a non-condensing relative humidity of 5 to 95%. Also, the 1756-EN2T communication module can withstand 2 grams at 10 to 500 Hertz vibration and 30 g of shock when operating. The module is certified according to various standards for controllers and similar industrial equipment. The included certifications include the c-UL-us, CE, CSA, RCM, FM, Ex, EAC, KC and EtherNet/IP standards.

The 1756-A17 is a ControlLogix I/O Chassis Based Module manufactured by Allen-Bradley under the ControlLogix Series. The module comes with 17-slot ControlLogix Chassis and has 6.1 Watts of power dissipation. The 1756-A17 has 1.8 Watts power consumption and a maximum backplane current of 1.5 Amps at 1.2 Volts DC, 4 Amps at 3.3 Volts DC, 15 Amps at 5.1 Volts DC, and 2.8 Amps at 24 Volts DC. The 1756-A17 communication system is made of EtherNet/IP networks and also makes use of the ControlNet networks. The 1756-A17 has a standard chassis that includes inherent time stamping capabilities for the some applications. Each of the modules within the chassis receives the power distributed by the chassis backplane. This happens because of the high-speed communication path between the modules.

The 1756-A17 requires a Bulletin 1492 Wiring IFM and it also uses a RTB for connection of all the field side wiring. When it comes to programming, the Studio 5000 Logix Designer Application Software is used. This application software includes an I/O wizard that allows quick and easy module configuration. Therefore, the 1756-A17 chassis is easy to install and maintain. As part of preventive maintenance, electronic keying is deployed that prevents replacement errors. The main feature that makes the 1756-A17 easy to maintain is the RIUP feature. Further, in case the 1756-A17 faces system or field side failure, it has a complete diagnostic feature that is helpful when it comes to identifying the failure. The 1756-A17 is one of the most cost-effective modules and it is easily compatible with the PanelView operator. The operating temperature for the 1756-A17 is -13 to 140 degrees Fahrenheit and the nonoperating temperature or the idle state temperature is -40 to 185 degrees Fahrenheit. The relative humidity is usually 5 to 95% non-condensing. When mounting the 1756-A17 ControlLogix with a standard power supply, it is important to ensure that the spacing requirements are followed.
