1756-EN2T

Allen-Bradley 1756-incubed tr is part – of the Controloaix communication module family. It is an Ethernet /IP(Ethernet Industrial Protocol) dual-port interface communication module. It supports universal messaging, real-time /0 messaging, and information exchange for applications such as real-time control, time synchronization, and motion. The 1756-in-tr also complies with CIP security standards by allowing simultaneous transmission of security and control data as well as diagnostic information. It uses advanced communication chips and physical media.
The 1756-sin gent tr module has a 10-100 Mbps Ethernet /IP communication rate and uses double copper wires. It supports 256 Logix and 128 TCP/IP communication connections. It can support integrated motion of up to 8 axes on A large network /IP network and consume 1 A current at 5.1V DC. It has a maximum power consumption of 51 watts and a heat dissipation of 17.4 BTU/ hour. It can be installed in any slot in the ControlLoqx case. For cabling, it uses an unshielded RJ45, Class 5, twisted pair electrical cargo connector to connect with the controller. To run an Ethernet /IP network, you need parameters such as an IP address, subnet mask, gateway, etc. Must be defined.
The 1756-1756 tr bridge has various features such as support for messaging, distributed /0, and labeling. It encapsulates the message in the standard TCP/IP protocol. The ControlNet and DeviceNet network protocols allow it to share a common application layer. The 1756-1756 tr does not require any scheduling or routing tables to store information. Additional features include explicit protection mode, electronic keys, device-level ring networking, and parallel multiprotocol networking support.
The 1756-in-tr is a ControLogix to large network communication module, specially designed for several Ethernet. With embedded dual RJ545 ports, support for Ethernet protocols and 10/100Mbps transfer speeds, with auto-negotiation capabilities, the module increases the availability of Ethernet networks.
The module supports ring and star topologies and qualified partner devices such as Flex 0, POINT 10 Ethernet adapters, CompactLogix, and ControlLogix. The module also supports sending messages to other Alen-Bradley controllers such as SLC 500, PLC-5 and Microloaix controllers, and it is compatible with human machine interface (HMI), monitoring and Data acquisition (SCADA) communications with the same Allen-Bradley and even third-party products. It can also work with endosure partner modules and square gateways, converters and devices.
The module also supports embedded Ethernet communication for computers and programming workstations, so there is no need to purchase an expensive communication adapter to establish a connection to the controller. In addition, the cable required for the module is Class 5 or Class 6 cable, which can be made into a communication cable.

The 1756-EN2T A-B Ethernet communication module decentralized control system is A process instrument control system specially designed for industrial process control, also known as distributed control system. According to the analysis of the development of programmable controller and DCS, the main application of distributed control system is continuous analog control, and the main application of programmable controller is the logic control of switching quantity. Therefore, there are certain differences in design ideas.
In factory automation or computer integrated process control system, in order to disperse risk and disperse function, a decentralized integrated control system structure is adopted. Programmable controller is a decentralized autonomous control system, which can be used as a subordinate computer to complete decentralized control functions, and has a qualitative leap compared with the centralized control of direct digital computer. This hierarchical control system is also the basis of decentralized control systems.
