Product Overview

The ABB DSMB176 57360001-HX functions as a dedicated memory expansion board for ABB Advant controller systems. This module increases program and data storage capacity for processors in industrial automation environments. We engineered the DSMB176 to provide reliable non-volatile memory for critical application code and process data.

Technical Specifications

Key Features and Benefits

• Expanded Program Capacity: The DSMB176 57360001-HX significantly increases available memory for ABB controllers. You implement larger, more sophisticated control strategies without hardware upgrades.

• Battery-Backed Data Protection: Onboard lithium battery preserves critical data in SRAM during power outages. Consequently, accumulated totals, setpoints, and retentive variables remain intact indefinitely.

• Dual-Technology Architecture: Flash memory stores programs permanently while SRAM handles dynamic data with fast access. This combination provides both security for application code and flexibility for changing process values.

• Hardware Write Protection: A physical switch prevents accidental overwriting of program memory. Therefore, you protect valuable control algorithms from unauthorized or inadvertent changes.

• Clear Status Indication: Front-panel LEDs show battery condition, write protection status, and module activity. These indicators simplify troubleshooting and maintenance significantly.

Detailed Functional Description

The primary function of the ABB DSMB176 57360001-HX involves providing additional non-volatile storage for ABB Advant controllers. Specifically, it plugs into the processor rack and connects directly to the VMEbus. The module appears as unified memory to the processor, automatically expanding the available address space. The Flash portion retains programs permanently without power, while the SRAM section holds dynamic data with battery backup. The module includes memory management logic that handles addressing and bus arbitration transparently.

Memory Architecture Details

We designed the DSMB176 with a dual-technology approach for optimal performance:

Battery Management and Monitoring

The ABB DSMB176 57360001-HX includes sophisticated battery monitoring to ensure data integrity:

• The lithium battery automatically maintains SRAM contents when system power removes

• A front-panel LED illuminates when battery voltage drops below 3.0V

• The module reports battery status to the controller for alarm generation

• Batteries are field-replaceable without removing the module from the rack

• A capacitor provides short-term hold during battery replacement

Installation and Configuration

Engineers install the DSMB176 directly into any available slot in the Advant controller rack. The process involves:

1. Inserting the module into the guided card guides

2. Pushing firmly to engage the backplane connector

3. Securing with the front-panel locking screws

4. Setting the write-protect switch as required

5. Verifying proper recognition by the controller

The controller automatically detects the additional memory during power-up and integrates it into the memory map without user configuration.

Mechanical Details

The ABB DSMB176 57360001-HX features a rugged Eurocard format construction for industrial reliability. Its front panel includes:

• Battery status LED (green/red)

• Write protect LED (amber)

• Module active LED (green)

• Write protect switch (accessible behind sealed cover)

• Captive mounting screws for vibration resistance

The module uses a 96-pin DIN 41612 connector for reliable connection to the VMEbus backplane. Gold-plated contacts ensure low resistance and corrosion resistance over many insertion cycles.
