Features:
- Stores shared AutoMax configuration data in 128K bytes of battery-backed RAM.
- Arbitrates backplane access for racks containing multiple processors.
- Includes the documented watchdog, lithium battery and super-capacitor protection.
The module provides shared data storage and bus coordination in AutoMax racks, especially where two or more processor modules operate together.
When installed in slot 0, it holds configuration information common to the processors and arbitrates their access to the rack bus. This removes shared configuration data from individual processor memory.
Preserve the common-memory database, processor-slot arrangement and battery condition before exchange. Do not replace a 57C413B with another revision without confirming memory capacity, backup method and supported programming-executive version.
Availability is reviewed against the exact 57C413B order identity and requested supply condition; manufacturer lifecycle status: Discontinued / Obsolete by OEM.

- A system watchdog supervises multi-processor operation. Battery-backed RAM retains the common database through a power interruption; the battery is not an uninterruptible operating supply.
- It may also be used in a single-processor rack to hold configuration data, or in another even slot as user-definable common storage. Application tasks and local variables are not stored in that auxiliary mode.
- Can provide user-definable common storage in an appropriate even-numbered slot.
- Provides shared configuration storage, bus arbitration, and watchdog functions.
- Coordinates data access for racks containing multiple processor modules.
- Slot-zero installation centralizes configuration data outside individual processor memory.
- Provides 128K bytes, equivalent to 64K registers, in slot zero.
- Uses an onboard lithium battery and super-capacitor for backup.
- The primary module belongs in slot zero of multiprocessor racks.
- Retains RAM for at least 600 days under documented battery conditions.
- An even non-zero slot provides 128K bytes of additional shared data.
- Draws 1.05 A from the rack's +5 V system supply.
