Product Introduction

Model Interpretation

• 0-57407-4: Full part number (leading 0 = standard processor; ‑4 = hardware revision 4).

• 57407: Product family = DCS 5000 Processor Module.

• ‑4: Revision 4, with enhanced firmware, improved fault handling, and backward compatibility with earlier 57407 revisions.

Technical Parameters

• Backplane Power: +5 VDC, ~800 mA.

• Processor: 16‑bit CPU, AutoMax real‑time OS.

• Memory: 64 KB RAM (with parity), 32 KB ROM.

• Isolation: 1500 VAC (field‑to‑logic).

• Operating Temperature: 0 °C to +55 °C.

• Humidity: 5%–95% non‑condensing.

• Weight: ~0.91 kg (2.0 lb).

• Rack Compatibility: 6/10/16‑slot AutoMax card racks (with cooling fans).

Interface & Front Panel

• Backplane: Edge connector for AutoMax dedicated backplane (power + data).

• RS‑232 Ports (2):

  • PROGRAMMER: For programming/debugging via AutoMax ReSource software.

  • LOCAL COMM: For HMI, SCADA, or peer‑processor communication.

• Front Panel:

  • OK LED: Green, indicates normal operation.

  • FAULT CODE (1ST/2ND): Two yellow pushbuttons for fault code display.

  • Reset Button: For module reset.

Core Functions

• Executes ladder logic, BASIC, and control block programs for integrated motion/process control.

• Manages system‑level coordination of I/O, drives, and network modules.

• Provides real‑time fault monitoring, logging, and diagnostics.

• Supports multi‑processor synchronization for coordinated drive systems.

• Enables offline/online programming and remote diagnostics via ReSource software.

Application Scenarios

• Legacy AutoMax DCS/PLC maintenance in metallurgy, paper, power, and material handling.

• Coordinated multi‑drive systems for rolling mills, conveyors, and web processing lines.

• High‑precision motion control for spindles, actuators, and process equipment.

• Retrofit/replacement of aging DCS processors in industrial automation modernization.

Operation & Maintenance

• Installation: Power off the rack; align and seat firmly, tighten mounting screws.

• ESD Protection: Use anti‑static wristband/mat; static damages sensitive circuits.

• Wiring: Use shielded cables for RS‑232; separate from high‑voltage lines to avoid EMI.

• Routine Maintenance: Quarterly inspection of cables/connectors; keep vents clean.

• Troubleshooting: Read fault codes via front‑panel buttons; verify LED status and switch settings.

• Replacement: Replace entire module if internal fault; do not repair PCB.

57407‑4 vs 57407‑2 (Key Differences)

• Hardware Revision: ‑4 is the latest revision; ‑2 is older.

• Firmware: ‑4 has updated firmware with better stability and bug fixes.

• Fault Handling: ‑4 provides enhanced fault diagnostics and error reporting.

• Compatibility: Both are pin‑compatible and interchangeable in AutoMax racks.
