Frequently Asked Questions (FAQ)

1. How does the DSMB-02C interact with other modules in the ABB INFI 90 system?
   The DSMB-02C acts as a control and interface board that facilitates communication between I/O modules and the main processor unit via the system bus. It helps manage signal distribution and logic control within a closed loop system.

2. What specific role does the DSMB-02C play in closed-loop process control?
   It performs intermediary control logic functions, ensuring that analog and digital signals from field devices are properly conditioned and routed to the main processing unit for real-time decision-making.

3. What diagnostic features are available on the DSMB-02C board?
   The board includes built-in status LEDs that indicate communication health, signal presence, and fault states. This helps during commissioning and troubleshooting in the field.

4. Is the DSMB-02C capable of handling analog signal processing, or is it purely digital?
   It supports both analog and digital signal pathways, depending on the module configuration. It doesn’t perform A/D conversion directly but interfaces with modules that do.

5. What are the main failure symptoms when the DSMB-02C malfunctions?
   Common signs include communication loss with peripheral modules, abnormal LED indicators, system watchdog alarms, or inconsistent I/O response within the control loop.

6. Can the DSMB-02C be used interchangeably with DSMB-01C or other variants?
   Not necessarily. While the boards may share similar functions, they have specific hardware mappings and firmware settings. Compatibility must be verified in the system’s hardware documentation.

7. What is the recommended procedure for replacing the DSMB-02C during plant operation?
   Shutdown is preferred for safety, but if the system supports hot-swapping and is redundantly configured, the board can be safely removed and replaced with minimal disruption. Follow ABB’s standard ESD and module handling guidelines.

8. What is the expected service life of a DSMB-02C control board under normal conditions?
   Typically, 10–15 years depending on environmental factors such as temperature, humidity, and electrical noise. ABB modules are known for extended field service when maintained properly.

9. How often should the DSMB-02C board be inspected or maintained?
   Visual inspection should be part of routine preventive maintenance (every 12–18 months), especially checking connector tightness, dust accumulation, and LED status indicators. No calibration is needed.

10. Does the DSMB-02C support redundant operation for critical applications?
    Yes, in most ABB DCS configurations, the control system can be set up in a redundant mode where two DSMB-02C boards operate in parallel, ensuring uninterrupted function even if one fails.
