1785-L40C15 可编程逻辑控制器 具有内置的通信端口

【产品详情】

Allen-Bradley 1785-L40C15是经典PLC5系列的可编程逻辑控制器(PLC)。该控制器是1785 ControlNet PLC5可编程控制器的一部分，配备双ControlNet通信接口，具有二级和三级接口。

1785-L40C15设计用于满足最大控制器内存高达48KWords，能够处理2048个I/ o或2048个输入和2048个输出，当在互补模式下操作时。它可以安装内存模块以达到内存限制。该控制器能够实现分布式I/O架构，兼容各种分布式I/O平台，如Bulletin 1771 I/O, 1794 I/O, 1746 I/O和1791 I/O模块，包括8点，16点，32点，专业和智能模块。

1785-L40C15配备了一个电池，用于保留处理器的随机存取存储器(RAM)。该电池的零件号为1770-XYC，只有在处理器主动供电时才可以更换。

该1785-L40C15还支持热备份系统通过1785-CBHM或ControlNet热备份墨盒。该模块安装在每个ControlNet处理器机架上，实现高速处理器切换和数据传输。

1785-L40C15具有内置的通信端口，如串行，数据高速公路+ (DH+)， DH使用1785-KA，远程I/O (RIO)和ControlNet。串行通信支持DF1和ASCII协议，通常用于下载、上传和点对点通信。数据高速公路Plus和远程I/O协议是支持与多个设备通信的高速网络协议。同样，ControlNet是一种网络协议，但在1785-L40C15上安装了2个ControlNet端口，支持热备份配置。

【英文介绍】

The Allen-Bradley 1785-L40C15 is a programmable logic controller (PLC) in the classic PLC5 family. The controller is part of the 1785 ControlNet PLC5 programmable controller and is equipped with dual ControlNet communication interfaces with secondary and tertiary interfaces.

The 1785-L40C15 is designed to meet a maximum controller memory of up to 48KWords, capable of handling 2048 I/ OS or 2048 inputs and 2048 outputs, when operating in complementary mode. It can install memory modules to reach memory limits. The controller is capable of implementing a distributed I/O architecture and is compatible with various distributed I/O platforms such as Bulletin 1771 I/O, 1794 I/O, 1746 I/O and 1791 I/O modules, including 8, 16, 32, professional and smart modules.

The 1785-L40C15 is equipped with a battery that holds the processor's random access memory (RAM). The battery has the part number 1770-XYC and can only be replaced when the processor is actively powered.

The 1785-L40C15 also supports hot backup systems via 1785-CBHM or ControlNet hot backup cartridges. The module is installed in each ControlNet processor rack, enabling high-speed processor switching and data transfer.

The 1785-L40C15 has built-in communication ports such as Serial, Data Highway + (DH+), DH using the 1785-KA, Remote I/O (RIO), and ControlNet. Serial communication supports both DF1 and ASCII protocols and is commonly used for download, upload, and peer-to-peer communication. The Data Superhighway Plus and Remote I/O protocols are high-speed network protocols that support communication with multiple devices. Again, ControlNet is a networking protocol, but there are 2 ControlNet ports installed on the 1785-L40C15 that support a hot backup configuration.
