1772-LG 处理器 控制模块

【产品详情】

Allen-Bradley 1772-LG控制模块是为Allen-Bradley PLC-2/30可编程控制器制造的处理器控制模块。PLC-2/30控制器系统由1771-LP3处理器和I/O结构组成，该结构是包含I/O模块的I/O机箱。当与I/O模块和用户编写的程序结合使用时，PLC-2/30可编程控制器可用于许多工业应用，包括过程控制，码垛，物料处理，污染控制/监测以及测量和测量应用。1772-LP3处理器包含一个CMOS存储器单元(读/写)，用于存储程序指令、I/O状态更新和数值。用户编写的程序包含详细说明需要执行的操作的指令。这个程序是从艾伦-布拉德利1770-T3或17840-T50终端输入的。

在程序执行期间，PLC-2/30处理器监视输入设备，并根据用户程序指令使输出设备通电或断电。用户程序可以根据应用程序的要求进行修改，因为存储器是可编程的。1772-LP3处理器的数据表容量可以在16k内存时增加到8192个字，在8k内存时增加到8064个字。当本地I/O机架使用1771-P3、1771-P4、1771-P5或1771-P7电源供电时，可能会导致1772-LG模块与机架出现问题。处于TEST或RUN模式的处理器在从电源锁定中恢复后尝试读取本地机架。这可能会导致1772-LG模块的处理器故障。如果确实出现问题，则应将处理器断电或将键开关置于程序加载位置，然后返回RUN模式。

【英文介绍】

The Allen-Bradley 1772-LG control module is a processor control module manufactured for the Allen-Bradley PLC-2/30 programmable controller. The PLC-2/30 controller system consists of the 1771-LP3 processor and the I/O architecture, which is an I/O chassis containing the I/O module. When used in combination with I/O modules and user-written programs, the PLC-2/30 programmable controller can be used in many industrial applications, including process control, palletising, material handling, pollution control/monitoring, and measurement and measurement applications. The 1772-LP3 processor contains a CMOS memory unit (read/write) for storing program instructions, I/O status updates, and numerical values. A program written by a user contains instructions detailing what needs to be done. This program is input from an Allen-Bradley 1770-T3 or 17840-T50 terminal.

During program execution, the PLC-2/30 processor monitors the input device and powers on or off the output device according to user program instructions. The user program can be modified according to the requirements of the application because the memory is programmable. The data table capacity of the 1772-LP3 processor can be increased to 8192 words with 16k of memory and 8064 words with 8k of memory. When a local I/O rack uses 1771-P3, 1771-P4, 1771-P5, or 1771-P7 power supply, it may cause problems with the 1772-LG module and rack. A processor in TEST or RUN mode attempts to read the local rack after recovering from the power lock. This could cause a processor failure in the 1772-LG module. If a problem does occur, power off the processor or place the key switch in the program load position and return to RUN mode.
