1756-L71SK 支持的安全通信选项包括以太网I/P

【功能描述】

1756-L71S主要具有2mb标准用户内存、1mb安全内存、0.98 MB I/O内存和1gb非易失性内存，这些内存由随控制器发货的预供应1784-SD1提供。与标准ControlLogix控制器类似，1756-L71S具有1个USB通信端口，用于编程、硬件配置和在线编辑。该控制器能够处理多达128,000个离散I/O点和4000个模拟I/O点。

1756-L71S支持的安全通信选项包括以太网I/P、ControlNet和DevideNet。与1756-CN2/A配套使用时，可支持100个ControlNet连接，1756-CNB/D、1756-CNB/E、1756-CN2/B分别为40个、128个。对于以太网，256以太网/IP;使用1756-EN2x和128以太网/IP允许128个TCP连接;64 TCP与1756-ENBT。

The 1756-L71S mainly has 2mb of standard user memory, 1mb of safe memory, 0.98 MB of I/O memory, and 1gb of non-volatile memory, which is provided by the pre-supply 1784-SD1 shipped 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 has standard and safety features. Standard features include I/O control, logic, timing, counting, report generation, communication, arithmetic calculations, and data file manipulation. The security function is 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 diagrams, sequential function diagrams (SFC) and other programming languages. For programming safety tasks, only relay ladder logic is allowed.

Secure communication options supported by the 1756-L71S include Ethernet I/P, ControlNet, and DevideNet. When used with the 1756-CN2/A, it supports 100 ControlNet connections, 40 1756-CNB/D, 1756-CNB/E, and 1756-CN2/B, 128 respectively. For Ethernet, 256 Ethernet /IP; Allows 128 TCP connections using 1756-EN2x and 128 Ethernet /IP; 64 TCP and 1756-ENBT.
