Reliance AutoMax common memory module, M/N 57C413A, is the shared memory component used in AutoMax racks that contain multiple processor modules. It stores configuration data and I/O definitions that must be accessible by all processors, enabling coordinated operation of the multi-processor control system. In AutoMax DCS 5000 racks, this module is typically installed in slot 0 when more than one processor module is present, enabling inter-processor communication and a consistent system state. It is listed alongside other common memory options (such as 57C423) as an approved memory module for AutoMax.
