Allen Bradley 1756-L84E is a ControlLogix controller. This controller belongs to a high-end controller with modern design and connectivity. This controller is very suitable for large-scale applications as it can be used to interface and control input and output devices, especially 128000 discrete inputs and outputs and 4000 analog inputs and outputs. It supports local I/O control and utilizes one or more communication protocols (For example, EtherNet/IP, ControlNet, DeviceNet, Data Highway Plus, Remote I/O, SynchLink, and third-party process and device networks implement a distributed I/O architecture 1756-L84E with integrated communication ports, such as an Ethernet I/P. This embedded port supports 10/100/1000 Mbps transmission speed and can be used to transmit instructions and human-machine interfaces (HMI) through the same Ethernet network.) Communication between SCADA and other controllers. The USB port is a USB 0.12 that supports 2 Mbps communication speed. The 1756-L84E has 20MB of built-in user memory. You can use 1784-SD2 to install extended non-volatile memory, which is a 2GB Secure Digital (SD) card.
