除了支持大量的I/O设备外，该控制器还能够实现远程I/O架构，因为它可以连接到最多28个远程I/O机架。为了实现远程I/O架构，可以利用DH+和Remote I/O (RIO)通道等集成通信端口。另外，可以添加以太网接口模块以在以太网网络上实现相同的体系结构。

1785-L30B内置电池，供控制器断电时使用。该电池维持存储在控制器用户存储器中的用户和程序数据。它被分配了一个BATT指示灯LED报告电池的当前充电。对于1785-L530B，在100%断电的情况下，电池续航时间可达84天，在60摄氏度的工作温度下，电池续航时间可达150天。当BATT LED通电时，电池从第一次出现信号开始保持5天的工作状态。当电池电量完全耗尽时，用户存储器的内容将保持，除非控制器通电。它只会被擦除，当电源被移除和电池耗尽。

1785-L30B有两个内置端口:通道1A和通道1B。这些端口可以配置为远程I/O扫描器、远程I/O适配器和DH+通信接口。此外，1785-L30B控制器提供了一个25针连接器串行端口接口。该串口支持RS232C标准，可配置系统协议，如ASCII和DF1。全双工和半双工主协议和半双工从协议。还提供标记为1A通道的8针mini-DIN连接器，支持DH+连接。

1785-L30B前面板上有几个指示灯，便于与用户交互。这些指示灯被标记为BATT，用于显示电池的状态。标有“PROC”的指示灯表示控制器状态。FORCE指示灯用于指示是否启用I/O强制。COMM指示灯与通道0连接，用于报告通信活动，而通道1A和1B都有专用的状态指示灯。

控制器有三个位置键开关，用于设置控制器模式。每个位置对应处理器的一种模式，如Run、PROG和REM。当处于Run模式时，控制器执行程序并激活输出设备。PROG停止逻辑执行，并允许控制器配置和编程。REM执行逻辑程序，允许配置和编程。

1785- l30b有32000字的内存和备用电池。对于程序备份，可以在前面板插槽中安装EEPROM模块。不同容量的内存模块可供选择。I/O的总数(包括本地I/O和通用远程I/O的组合)是1024个任意组合，或者1024个输入和1024个输出互补。1785-L30B总共可以利用29个I/O机箱，其中28个可作为通用远程I/O机箱。背板的电流负载为1785-L30B在5伏时为2.3安培。1785-L30B不具备连接扩展本地I/O机箱的能力。

【英文介绍】

The 1785-L30B is an Allen-Bradley controller belonging to the PLC5 controller family. The controller features 32Kwords user memory, two (2)DH+/ remote I/O combination ports, configurable adapters or scanners, and one (1) serial port with support for RS-232, 423, and RS-422A communication standards.

The 1785-L30B supports a large number of I/O devices. It supports up to 1024 I/O devices and can be composed of any combination of discrete and analog input and output devices. In addition, it supports complementary 1024 input and 1024 output devices.

In addition to supporting a large number of I/O devices, the controller enables a remote I/O architecture as it can be connected to up to 28 remote I/O racks. To implement the Remote I/O architecture, integrated communication ports such as DH+ and Remote I/O (RIO) channels can be utilized. In addition, Ethernet interface modules can be added to implement the same architecture on an Ethernet network.

1785-L30B Built-in battery for use when the controller is powered off. The battery maintains user and program data stored in the controller's user memory. It is assigned a BATT indicator LED to report the current charge of the battery. For the 1785-L530B, the battery lasts up to 84 days with 100 percent power off, and 150 days at an operating temperature of 60 degrees Celsius. When the BATT LED is powered on, the battery remains in working condition for 5 days from the first signal. When the battery is completely drained, the contents of the user's memory are maintained unless the controller is powered on. It will only be erased when the power supply is removed and the battery is exhausted.

The 1785-L30B has two built-in ports: Channel 1A and Channel 1B. These ports can be configured as remote I/O scanners, remote I/O adapters, and DH+ communication interfaces. In addition, the 1785-L30B controller offers a 25-pin connector serial port interface. The serial port supports the RS232C standard and can be configured with system protocols such as ASCII and DF1. Full duplex and half duplex master protocols and half duplex slave protocols. An 8-pin mini-DIN connector labeled 1A channel is also available, supporting DH+ connections.

The 1785-L30B has several indicators on the front panel for easy interaction with the user. These indicators are labeled BATT and are used to show the status of the battery. An indicator labeled "PROC" indicates controller status. FORCE indicator Indicates whether to enable I/O force. The COMM indicator is connected to channel 0 for reporting communication activity, while channels 1A and 1B both have dedicated status indicators.

The controller has three position key switches for setting the controller mode. Each position corresponds to a mode of the processor, such as Run, PROG, and REM. When in Run mode, the controller executes the program and activates the output device. PROG stops logic execution and allows controller configuration and programming. REM executes logic programs that allow configuration and programming.

The 1785-l30b has 32,000 words of memory and a backup battery. For program backup, an EEPROM module can be installed in the front panel slot. Memory modules of different capacities are available. The total number of I/ OS (including a combination of local I/ OS and generic remote I/ OS) is 1024 in any combination, or 1024 input and 1024 output complementary. The 1785-L30B can utilize a total of 29 I/O enclosures, 28 of which can be used as general purpose remote I/O enclosures. The backplane has a current load of 1785-L30B and 2.3 amps at 5 volts. The 1785-L30B does not have the ability to connect to an extended local I/O chassis.
