【功能描述】

Allen-Bradley 1785-L40C15 是經典 PLC5 系列的可編程邏輯控制器 （PLC）。該控制器是 1785 ControlNet PLC5 可編程控制器的專用部分，配備具有二級和三級接口的雙 ControlNet 通信接口。

1785-L40C15 設計用于滿足高達 48KWord 的最大控制器內存，在互補模式下運行時能夠處理 2048 個 I/O 或 2048 個輸入和 2048 個輸出。它可能與內存模塊一起安裝以達到內存限制。該控制器能夠實現(xiàn)分布式 I/O 體系結構，并兼容各種分布式 I/O 平臺，如 Bulletin 1771 I/O、1794 I/O、1746 I/O 和 1791 I/O 模塊，包括 8 點、16 點、32 點、專用和智能模塊。

1785-L40C15 配備電池，用于保留處理器的隨機存取存儲器 （RAM）。此電池的部件號為 1770-XYC，只有在處理器主動供電時才能更換。

1785-L40C15 還支持通過 1785-CBHM 或 ControlNet 熱備份磁帶的熱備份系統(tǒng)。該模塊安裝在每個 ControlNet 處理器機架上，用于實現(xiàn)高速處理器切換和數(shù)據傳輸。

1785-L40C15 具有內置通信端口，例如串行、Data Highway Plus （DH+）、使用 1785-KA 的 DH、遠程 I/O （RIO） 和 ControlNet。串行通信支持 DF1 和 ASCII 協(xié)議，通常用于下載、上傳和點對點通信。Data Highway Plus 和遠程 I/O 協(xié)議是高速網絡協(xié)議，支持與多個設備進行通信。同樣，ControlNet 是一種網絡協(xié)議，但是，1785-L40C15 安裝了兩 （2） 個 ControlNet 端口，支持熱備份配置。

【英文介紹】

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 1785-L40C15 is installed with two (2) ControlNet ports that support a hot backup configuration.
