Memory Module | 1766-MM1 | Allen Bradley

A MicroLogix 1400 memory module called the 1766-MM1 offers more space for user data and program storage. By using this memory module, controller data corruption or inadvertent deletion are avoided. Program comparison, data file protection, write protection for memory modules, and removal/insertion under power are more features it offers.

Brand:  Allen Bradley

Model:  1766-MM1

Type:    Memory Module

 

Introduction:

A member of the MicroLogix 1400 Programmable Controller family is the Allen-Bradley 1766-MM1 Memory Module. It is a memory module that offers more user program and data backups. It also permits software transfers between controllers. This module offers a memory that is allocated individually rather than increasing the integrated. Its memory is 384 KB in size. MicroLogix 1400 controllers, including models 1766-L32AWA, 1766-L32AWAA, 1766-L32BWA, 1766-L32BWAA, 1766-L32BXB, and 1766-L32BXBA, are compatible with this memory module.

Other capabilities of the 1766-MM1 Memory Module enable it to compare the programs that are kept in its memory. It permits auto-recovery via a power cycle in the event of any controller malfunction. While the controller operates, you can add or delete the 1766-MM1. It protects the data files stored in the memory module from being written to. The Memory Module port and cover for the 1766-MM1 are installed when these controllers are shipped. You can also set it up using the given screen and the system prompts to instruct the memory module’s controller to load. The controller will then get the contents of the memory module.
