A-B 1771-AL

The 1771-AL belongs to the 1771 series products under the Allen Bradley brand of Rockwell Automation. This series of universal I/O modules provides comprehensive digital, analog, and special function I/O for a wide range of application projects, which can be used for PLC-5 ® The local I/O rack of the system can also be placed in a rack far away from the controller through the I/O communication adapter module

The 1771- adapter module can be used with any 1771 I/O chassis. Communication between the discrete analog module and the processor is bidirectional; the processor block-transfers output data through the output image table to the module and block-transfers input data from the module through the input image table. The module also requires an area in the data table to store the read block transfer data and write block transfer data. I/O image table use is an important factor in module placement and addressing selection.

1771-AL属于罗克韦尔自动化公司Allen-Bradley品牌下的1771系列产品。 该系列的通用I/O模块为广泛的应用项目提供了全面的数字量、模拟量和特殊功能I/O，可用于PLC-5®系统的本地I/O机架，也可通过I/O通信适配器模块将I/O置于远离控制器的机架中.

1771适配器模块可以与任何1771 I/O机箱一起使用。离散模拟模块和处理器之间的通信是双向的；处理器块通过输出图像表将输出数据传输到模块，并且块通过输入图像表将输入数据从模块传输。该模块还需要数据表中的一个区域来存储读块传输数据和写块传输数据。I/O映像表的使用是模块放置和寻址选择的重要因素。
