1. Product Overview

• Model: ILX56‑MM (ProSoft Technology)

• Platform: Rockwell Automation ControlLogix 1756 chassis (single‑slot)

• Type: InRAx Message Manager – high‑performance, multi‑protocol communication module

• Purpose: Enables tag‑based, event‑driven data exchange between ControlLogix and disparate networks/protocols without custom code

• Form Factor: Single‑slot, fits standard 1756 backplane

2. Key Features

• Dual Ethernet Ports (RJ45): 10/100 Mbps, independent network segmentation

• Multi‑Protocol Support:

  • EtherNet/IP (native Logix)

  • Modbus TCP/IP (Client/Server)

  • Siemens Industrial Ethernet (S7)

  • ControlNet, DH+, DH485 (via bridging)

• Up to 16 Independent Communications – separately configured connections

• Tag‑Based Data Exchange: Browse local/remote Controller Tags; map directly to messages

• Flexible Triggering:

  • On tag value change (event‑driven)

  • On time interval (polled)

• Built‑in Web Server: Full configuration via browser – no extra software needed

• Data Sizes: Up to 1000 words per message; large transfer support

• Diagnostics: Per‑connection status, error counters, and health tags in Logix controller

3. Technical Specifications

General

• Backplane: 1756 ControlLogix, single slot

• Backplane Current: 1000 mA @ 5 VDC

• Dimensions: 190 × 129 × 20 mm (H × W × D)

• Weight: ~1.6 kg

Ethernet

• Humidity: 5%–95% non‑condensing

• Shock/Vibration: 30 g operational; 50 g non‑operational

Protocols & Connections

• Max Connections: 16 (configurable mix of protocols)

• Message Types: Read/Write, Unscheduled, Event, Polled

4. LED Indicators

• PWR: Green = backplane power OK

• STAT: Green = running; Red = fault

• NET1 / NET2: Green = link; Flashing = activity

• LINK: EtherNet/IP connection status

5. Typical Applications

• Connect ControlLogix to Modbus TCP devices (meters, drives, gateways)

• Exchange data with Siemens S7 PLCs over Ethernet

• Bridge ControlNet / DH+ / DH485 systems to EtherNet/IP

• Centralize multi‑vendor data into a single ControlLogix controller

• Build distributed SCADA with event‑driven updates

6. Advantages

• No Custom Code: Configure via web; map tags directly

• Multi‑Protocol in One Module: Reduce chassis slots and cost

• Event‑Driven = Lower Traffic: Only send data when values change

• Native ControlLogix Integration: Uses standard Studio 5000 tags

• Dual Ethernet: Segregate control and data networks
