1785-L40C15 是一款ControlNet PLC5可编程逻辑控制器

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 可编程控制器的专用部分，配备具有二级和三级接口的双 ControlNet 通信接口。

1785-L40C15 设计用于满足高达 48KWord 的最大控制器内存，在互补模式下运行时能够处理 2048 个 I/O 或 2048 个输入和 2048 个输出。它可能与内存模块一起安装以达到内存限制。该控制器能够实现分布式 I/O 体系结构，并兼容各种分布式 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、专用和智能模块。

1785-L40C15 配备电池，用于保留处理器的随机存取存储器 （RAM）。此电池的部件号为 1770-XYC，只有在处理器主动供电时才能更换。

1785-L40C15 还支持通过 1785-CBHM 或 ControlNet 热备份磁带的热备份系统。该模块安装在每个 ControlNet 处理器机架上，用于实现高速处理器切换和数据传输。

1785-L40C15 具有内置通信端口，例如串行、Data Highway Plus （DH+）、使用 1785-KA 的 DH、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。Data Highway Plus 和远程 I/O 协议是高速网络协议，支持与多个设备进行通信。同样，ControlNet 是一种网络协议，但是，2-L1785C40 安装了两 （15） 个 ControlNet 端口，支持热备份配置。

1785-L40C15 是一款ControlNet PLC5可编程逻辑控制器

The Allen-Bradley 1785-L40C15 is a programmable logic controller (PLC) in the classic PLC5 family. The controller is a dedicated part of the 1785 ControlNet PLC5 programmable controller, 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 48KWord and is capable of handling 2048 I/ OS or 2048 inputs and 2048 outputs when running in complementary mode. It may be installed with a memory module to reach memory limits. The controller implements a distributed I/O architecture and is compatible with a variety of 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, dedicated and smart modules.

The 1785-L40C15 is equipped with a battery to retain the processor's random access memory (RAM). This 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 tapes. This module is installed in each ControlNet processor rack for high-speed processor switching and data transfer.

The 1785-L40C15 has built-in communication ports such as serial, Data Highway Plus (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. Data Highway Plus and Remote I/O protocols are high-speed networking protocols that enable communication with multiple devices. Again, ControlNet is a networking protocol, however, the 2-L1785C40 has two (15) ControlNet ports installed and supports a hot backup configuration.
