【英文介绍】
The Allen-Bradley 1756-L71S is a GuardLogix 5570 controller that is part of the Logix5000 family of controllers. It is a ControlLogix controller with security features. It is a dual-processor solution that must be used in conjunction with the 1756-L7SP safety module to meet the requirements of SIL 3 or Cat. 4/PLe Safety standard. The security Partner controller is automatically configured, providing major advantages for individual projects. It has powerful processing power and motion speed as well as high-performance logic. It has a USB port for communication and can support up to 500 controller connections. The 1756-L71S controller has 2MB of user memory, 1MB of security memory, and 0.98MB of I/O memory. It can support 128,000 digital I/ OS and 4,000 analog I/ OS. It absorbs 2mA current at 5.1V DC and 1mA current at 800.5V DC. It has a power consumption of 2.5W and a thermal dissipation of 8.5 BTU/hr. It weighs 0.55 pounds and has an isolation voltage of 30V (continuous) for basic insulation. It can be installed in any slot in the ControlLogix 1756 chassis. For secure communication, it uses ControlNet, DeviceNet, or EtherNet/IP networks. The 1756-L71S controller can control or monitor I/O through the backplane or through the I/O link. For controller diagnostics, it has a front panel display that provides runtime information. It works with 1756-ESMCAP and 1756-ESMCAPK energy storage modules, which means there is no need for a lithium battery. The 1 GB (1784-SD1) secure digital card comes pre-loaded as optional non-volatile storage, expandable up to 2 GB (1784-SD2).
The 1756-L71S mainly has 2 MB of standard user memory, 1 MB of safe memory, 0.98 MB of I/O memory, and 1 GB of non-volatile memory, and is provided by the pre-shipped 1784-SD1 with the controller. Similar to the standard ControlLogix controller, the 1756-L71S has a USB communication port for programming, hardware configuration, and online editing. The controller is capable of handling up to 128,000 discrete I/O points and 4,000 analog I/O points.
The 1756-L71S performs both standard and safety functions. Standard features include I/O control, logic, timing, counting, report generation, communication, arithmetic calculations, and data file manipulation. Security functions are communicated from the master controller to the partner security controller. The 1756-L71S does not support controller redundancy and is programmed using relay ladder logic (RLL), structured text, function block diagram, Sequential Function diagram (SFC) and other programming languages. For programming safety tasks, only relay ladder diagrams are allowed.
Secure communication options supported by the 1756-L71S include Ethernet I/P, ControlNet, and DevideNet. If used with the 1756-CN2/A, 100 ControlNet connections are supported, 40 are 1756-CNB/D, 1756-CNB/E connections, and 128 are connected to the 1756-CN2/B connections. For Ethernet, 256 Ethernet /IP; Allows 128 TCP connections using 128-EN1756X and 2 Ethernet /IP; 64 TCP and 1756-ENBT.
