1. Product Overview

Model: CLX-APACS
Manufacturer: ProSoft Technology
Product Type: In-chassis plug-in module for Allen-Bradley ControlLogix system
Function: This module is directly installed inside ControlLogix rack. It enables ControlLogix and Plant-PAx control systems to communicate seamlessly with legacy Moore APACS+ DCS I/O bus. It realizes phased system migration, allowing users to upgrade old APACS DCS systems to modern Rockwell automation platforms without replacing on-site I/O hardware.

2. Main Features

  1. Standard ControlLogix backplane design, plug and play without extra power supply

  2. Support two operation modes for safe system migration: Monitor Mode and Master Mode

  3. Compatible with all mainstream APACS+ digital and analog I/O modules

  4. Support up to 39 sets of IO bus cards on single network segment

  5. Large capacity I/O data processing, support 4464 discrete points and 1116 analog points

  6. Automatically import APACS configuration files from 4-Mation software

  7. Auto map APACS I/O data into native ControlLogix tags

  8. Complete network diagnosis function, all fault status uploaded to controller

  9. Configure and download parameters via RSLinx Classic software

  10. Stable industrial grade performance, suitable for long-term continuous operation in process industry

3. Operation Modes

Monitor Mode

Run ControlLogix program synchronously with original APACS ACM controller, realize data comparison and function verification. It will not affect existing production operation, used for pre-migration debugging and test.

Master Mode

Disable original APACS main controller, ControlLogix takes full charge of APACS I/O bus and all field control logic, complete formal system replacement and upgrade.

Bus LED: Indicate APACS I/O bus connection and data transmission status
Fault LED: Light up when communication error, configuration error or bus abnormal occurs

6. Installation and Configuration Steps

  1. Power off the whole ControlLogix rack system

  2. Insert CLX-APACS module into empty standard slot of ControlLogix chassis

  3. Connect APACS+ field I/O bus cable to module external communication port

  4. Power on the system, confirm module is identified by ControlLogix controller

  5. Import APACS project configuration file through matching configuration tool

  6. Select working mode according to project requirement

  7. Complete data tag mapping, download configuration and run system test

  8. Verify input and output data consistency before formal putting into use

7. Application Scope

  1. Moore APACS+ legacy DCS system upgrade and reconstruction projects

  2. Power plant, chemical industry, oil and gas large process control system migration

  3. Keep original field I/O equipment, only upgrade upper-layer control system

  4. Hybrid networking of new Rockwell system and old APACS automation equipment

  5. Industrial automation system gradual replacement and low-stop production transformation

  6. Centralized unified monitoring and management of scattered APACS remote I/O stations

8. Advantages

  1. Realize risk-free gradual migration, effectively reduce production shutdown time

  2. Reuse existing field I/O hardware, greatly save project renovation cost

  3. Built-in chassis module design, shorter data transmission delay than external gateway

  4. Native integration with Logix platform, convenient programming and maintenance

  5. Perfect compatible with mainstream ControlLogix firmware versions

  6. Professional long-term firmware upgrade and technical after-sales support

9. Safety Notes

  1. All module plugging and wiring operations must be completed under power-off state

  2. Keep APACS field bus wiring standard and correct, ensure communication stability

  3. Confirm working mode selection correctly to avoid production control logic conflict

  4. Regularly check module running status and bus communication quality

  5. Professional automation engineers are recommended to complete configuration debugging and system switching work
