Product Overview

Model Definition

Technical Parameters

• Network Protocol: Proprietary R‑NET (Reliance Network) for AutoMax systems.

• Communication Speed: Up to 1 Mbps (R‑NET backbone).

• Supported Nodes: Up to 32 nodes per R‑NET segment.

• Isolation: 2500 VAC RMS galvanic isolation between network and backplane.

• Operating Voltage: 5 VDC and ±12 VDC (backplane‑powered).

• Operating Temperature: 0 °C to +60 °C.

• Status Indicators: Dual LEDs (OK/Fault) for module and network status.

• Installation: Single‑slot, hot‑swap capable in standard AutoMax racks.

Interface and Communication Configuration

• Backplane Interface: Dedicated edge connector for power and data via AutoMax Multibus.

• Network Port: Isolated RJ45 or terminal block for R‑NET network wiring.

• Communication Protocol: R‑NET master/slave communication; supports peer‑to‑peer data sharing between AutoMax processors.

• Compatibility: Works with 57C404C, 57C417, and other AutoMax communication modules; integrates with AutoMate PLCs via gateway.

Core Functions

• Establishes and manages R‑NET network communication for AutoMax systems.

• Transmits real‑time control data, status information, and diagnostic messages between distributed controllers and I/O racks.

• Provides galvanic isolation to protect the main system from network‑side electrical noise and faults.

• Supports network configuration, node addressing, and fault diagnosis via system software.

• Enables redundant communication paths for high‑availability system designs.

Application Scenarios

• Process industries: Steel, pulp and paper, water treatment, chemical, and power plants with distributed control.

• Factory automation: Assembly lines, material handling, and packaging machinery requiring multi‑rack coordination.

• System integration: Connecting AutoMax processors, remote I/O racks, and third‑party devices via R‑NET.

• Motion control: Synchronizing multiple drives and controllers in complex motion applications.

Operation and Maintenance Instructions

• Power off the rack before installation or removal.

• Insert the module into the designated slot and ensure firm backplane contact.

• Wire the R‑NET network to the correct port, observing polarity and termination requirements.

• Configure network parameters (node address, baud rate, redundancy) via AutoMax system software.

• Keep the rack clean, dry, and well‑ventilated; avoid corrosive gases and excessive vibration.

• Monitor LED indicators periodically; replace the module with the same part number if faults persist.

• Do not disassemble or modify the module; repairs must be performed by authorized personnel.
