More Information

Overview Manuals Applications Connectivity Diagnostics Operating Environment

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.
Verified resources for Reliance Electric 57C413B:Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • 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.

The module provides shared data storage and bus coordination in AutoMax racks, especially where two or more processor modules operate together.
Which slot must hold the primary Reliance Electric 57C413B?
The manufacturer data specifies Primary position as Slot 0 in a rack with more than one processor; the installed arrangement must match that exact value.
How does Reliance Electric 57C413B arbitrate shared bus access?
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.
What memory records must be preserved before replacing Reliance Electric 57C413B?
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.
How should Reliance Electric 57C413B obsolescence guide procurement?
The page records Discontinued / Obsolete by OEM. Apter Power reviews the exact order identity and condition without presenting this as an OEM delivery promise.
Which battery and storage mode distinguish Reliance Electric 57C413B?
Submit the complete nameplate, Additional storage mode (128K bytes in an even non-zero slot for user-definable common data), installed system evidence, condition, quantity and destination so the document and quotation match 57C413B.
