Allen-Bradley Memory Communication Module

• Part number: 1775-MX
• Product family: PLC-3
• Lifecycle status: END OF LIFE - Discontinued

Technical Specifications:

• Backplane Current Requirements: High speed transfer of data table and ladder diagram program information from primary to backup PLC-3 processor requires 3.5A max at +5V DC per module.
• The two memory communication modules can be connected using a 1775-CM cable assembly.

Product Features:

• The 1775-MX is a memory communication module that quickly transfers data table information from the primary to the backup processor in a PLC-3 backup system.
• In a PLC-3 backup system, you need to insert memory communication modules in both the primary and backup PLC-3 processor chassis.
• The communication between primary and backup memory communication modules is valuable for critical applications in which large amounts of data must transfer from the primary PLC-3 processor to the backup PLC-3 processor.
• In these applications, memory communication modules provide high speed data transfer which reduces the possibility of unexpected operation at switchover.
• The 1775-MX provides protection from unexpected shutdowns during the industrial processes that can prove to be very costly.
• The memory communication module is used for adding a network interface to the motors and parts it is connected to.
• The major use of 1775-MX is to store data and create a backup system during industrial processes.
• The module has the ability to transfer control to the backup PLC-3 processor when the ladder diagram program detects specific conditions.
• It has a high speed update of data table contents.
• It can update contents of user-selected files.
• It can stop any continuous data transfer at the completion of a data table transfer or at the completion of the current file list transfer
