1764-LPR 处理器 提供大容量存储器解决方案

【产品详情】

Allen-Bradley 1764-LRP 是 MicroLogix 1500 处理器。它是 MicroLogix 1500 可编程控制器的一个组件，可为各种应用提供大容量存储器解决方案。它为数据和程序提供 14K 字的用户可配置存储器。对于 1K 字的程序（包括位、计数器、定时器和数学指令），它的程序执行时间约为 1 毫秒。在控制器系统中，1764-LRP 处理器单元提供微调电位器、运行/远程/编程模式开关、通信切换按钮和逻辑处理。它用作实时时钟、DAT 和内存模块的接口。该处理器使用控制器组合件来支持附加 I/O bank 中最多 8 个 I/O 模块。

1764-LRP 处理器带有一个额外的通信端口，DTE（公）9 针 D 外壳连接器，具有 30 伏直流隔离。该 RS-232 端口是电气隔离的，用于点对点和 SCADA/RTU 网络、DeviceNet、EtherNet/IP 和 DH-485 端口。它可以针对任何支持的通信协议单独配置（通道 1）。由于 1764-LRP 是标准处理单元的增强版本，因此将使用 1764-LRP 的 MicroLogix 控制器系统连接到计算机时不需要隔离器。一旦电池指示灯亮起，该模块就需要备用电池，因为原装电池只能使用至少 7 天。

Allen-Bradley 制造的 1764-LRP 是一款 MicroLogix 1500 控制器，主要用于小型、低级应用。该控制器直接连接到任何 MicroLogix 1500 基本单元，例如 1764-24AWA、1764-24BWA 和 1764-28BXB。它配有一个单独配置的双 RS232 端口。MicroLogix 1500 产品系列（包括 1764-LRP 的基本单元）专为 DIN 导轨安装而设计。它还支持本地扩展模块的安装，以及通过DeviceNet通信模块（特别是1764-SDN）使用I/O通信组进行远程安装。通过使用该模块，控制器能够与多达 63 个从设备进行通信。

1764-LRP 集成内存分为 10 KB 用户程序和 4 KB 用户数据。它的额定处理速度高达每 1K 个用户程序 1 毫秒。通过提供的集成存储器，该控制器能够处理多达 512 个 I/O，包括扩展模块。

1764-LRP 支持数据记录。它可能随时间或事件触发而触发。这允许在 48 KB 内存中存储带有时间戳的受控数据存储。此日志记录可用于数据历史化和分析。

1764-LRP 通信通道 1 是一个隔离的 RS232 端口，可用于点对点通信，通过 DH485、DeviceNet 和以太网 I/P 与 HMI、SCADA、RTU 系统进行数据交换。 |

1764-LRP 中的数据可以使用锂电池进行保护。该电池可更换部件号为 1747-BA。可以通过处理器提供的 LED 指示灯监控此电池。一旦指示灯被激活，这意味着电池电量将在七 （7） 天内耗尽。只要外部电源处于活动状态，就可以随时更换电池。切勿尝试在没有电源的情况下更换电池。

【英文介绍】

The Allen-Bradley 1764-LRP is a MicroLogix 1500 processor. It is a component of the MicroLogix 1500 programmable controller that provides mass memory solutions for a variety of applications. It provides 14K word user configurable memory for data and programs. For a 1K word program (including bits, counters, timers, and mathematical instructions), its program execution time is about 1 millisecond. In the controller system, the 1764-LRP processor unit provides fine-tuning potentiometers, run/remote/programming mode switches, communication toggle buttons, and logic processing. It serves as an interface to the real-time clock, DAT, and memory modules. The processor uses a controller assembly to support up to eight I/O modules in an additional I/O bank.

The 1764-LRP processor comes with an additional communication port, DTE (male) 9-pin D-housing connector with 30 volt DC isolation. The RS-232 port is electrically isolated and is used for point-to-point and SCADA/RTU networks, DeviceNet, EtherNet/IP, and DH-485 ports. It can be configured individually for any supported communication protocol (channel 1). Because the 1764-LRP is an enhanced version of the standard processing unit, an isolator is not required to connect a MicroLogix controller system using the 1764-LRP to a computer. Once the battery indicator lights up, the module needs a backup battery, as the original battery only lasts for at least seven days.

The 1764-LRP, manufactured by Allen-Bradley, is a MicroLogix 1500 controller designed primarily for small, low-level applications. The controller connects directly to any MicroLogix 1500 base unit, such as the 1764-24AWA, 1764-24BWA, and 1764-28BXB. It comes with a separately configured dual RS232 port. The MicroLogix 1500 product family, including the base unit of the 1764-LRP, is designed for DIN rail mounting. It also supports the installation of local extension modules, as well as remote installation via the DeviceNet communication module (specifically 1764-SDN) using the I/O communication group. By using this module, the controller is able to communicate with up to 63 slave devices.

1764-LRP integrated memory is divided into 10 KB of user programs and 4 KB of user data. It has a rated processing speed of up to 1 millisecond per 1K user programs. With the provided integrated memory, the controller is capable of handling up to 512 I/ OS, including expansion modules.

1764-LRP supports data logging. It can be triggered at any time or event. This allows a time-stamped controlled data store to be stored in 48 KB of memory. This log record can be used for data historization and analysis.

1764-LRP Communication Channel 1 is an isolated RS232 port that can be used for point-to-point communication to exchange data with HMI, SCADA, and RTU systems via DH485, DeviceNet, and Ethernet I/P. |

The data in the 1764-LRP can be protected using a lithium battery. The battery replaceable part number is 1747-BA. This battery can be monitored through the LED indicator provided by the processor. Once the indicator light is activated, this means that the battery power will be exhausted within seven (7) days. As long as the external power supply is active, the battery can be replaced at any time. Never attempt to replace a battery without a power source.
