ABB DSMB116 5736 0001-EB Replacement for DSMB Series

Product Overview

ABB DSMB116 5736 0001-EB Replacement for DSMB Series: Seamless Transition & Legacy System Compatibility

The ABB DSMB116 (Part No. 5736 0001-EB) is a memory module designed for ABB’s DSMB Series within the Advant Controller AC110/AC160 platform — a widely deployed DCS and PLC architecture in process automation, power generation, and heavy industry. As ABB progressively phases out legacy Advant hardware, many facilities operating on AC110, AC160, or Master Bus 300 architectures face urgent decisions: source a verified replacement module or plan a structured migration to a supported platform.

TOPNLMS maintains verified stock of the DSMB116 5736 0001-EB to support both strategies — immediate like-for-like replacement to restore system operation, and phased migration planning for facilities transitioning to ABB’s System 800xA or AC800M controller families.

Seamless Upgrade Solutions

A successful migration from an Advant-based system running the DSMB116 5736 0001-EB typically involves coordinating several interdependent hardware components. The DSPU116 processor unit, which hosts the DSMB116 memory module, must be evaluated first — if the processor itself is approaching end-of-life, a parallel replacement of both the DSPU116 and DSMB116 is strongly recommended to avoid a secondary unplanned outage.

On the I/O side, facilities commonly operate DSDI110A digital input modules and DSDO110A digital output modules within the same S100 sub-rack. These modules communicate over the MB300 bus and are directly supervised by the processor-memory pair. During a phased migration, these I/O modules can often remain in service while the processor and memory are upgraded, provided the new controller supports MB300 gateway bridging via a CI520 or CI522 communication interface module.

Power integrity is critical during any memory module swap. The DSMB116 relies on battery-backed RAM to retain program data during power cycling. Before removal, engineers should verify the DSBAT115 battery module condition and replace it concurrently if battery health is degraded — a common oversight that leads to program loss during the swap procedure.

For facilities migrating to the AC800M platform, the TB820 Modulebus modem and S800 I/O stations (such as AI810 analog input and AO810 analog output modules) form the backbone of the new I/O architecture. The migration project typically includes installing a PM866 or PM891 processor module in the new AC800M rack, reconfiguring I/O channel assignments in Control Builder M, and performing a parallel-run validation before cutting over from the legacy Advant system.

HMI integration is another key consideration. Legacy Advant systems often interface with older Operator Station (OS) hardware running Advant Station software. During migration, these are typically replaced with ABB’s 800xA Operations workplace or third-party SCADA systems communicating via OPC DA/UA. Signal isolation between the legacy and new system during parallel operation is commonly handled using DIN-rail mounted signal isolators or HART multiplexers, depending on the field instrument types in use.

For communication-intensive applications, the DSCB110 communication board and DSCS140 serial communication module are frequently encountered in the same control cabinet as the DSMB116. These modules handle serial fieldbus and inter-controller communication and must be accounted for in the migration bill of materials.

Retrofit Guidance FAQ

Q: Can I replace the DSMB116 5736 0001-EB without rewiring the field terminals?
A: Yes. The DSMB116 is a memory module that plugs into the DSPU116 processor unit — it has no direct field wiring connections. Replacement requires only powering down the processor unit, swapping the module, and performing a program reload from backup media or an engineering workstation. Field terminal wiring on the S100 I/O sub-rack is unaffected.

Q: Will my existing AMPL or Master Pieces program run on the replacement DSMB116?
A: Yes, provided the replacement module is the same part number (5736 0001-EB) and the program backup is intact. TOPNLMS supplies verified modules that are functionally equivalent to the original ABB production units. Program compatibility is maintained at the binary level for like-for-like replacements.

Q: What communication protocols does the DSMB116 platform support?
A: The Advant AC110/AC160 platform communicates via the proprietary Master Bus 300 (MB300) serial bus for inter-module communication. External communication to SCADA or DCS supervisory layers is handled by dedicated communication modules such as the DSCB110 or DSCS140, supporting protocols including MODBUS RTU, PROFIBUS DP (via gateway), and proprietary ABB plant communication bus (PLCB).

Q: How much physical space is required for installation?
A: The DSMB116 occupies a single module slot in the Advant S100 sub-rack. No additional rack space is required for a like-for-like replacement. For migration to AC800M, a new S800 I/O rack and AC800M controller rack must be accommodated in the control cabinet — typically requiring a cabinet expansion or a new cabinet section.

Q: How do I minimize downtime during the replacement?
A: Pre-stage the replacement DSMB116 and verify the program backup before scheduling the maintenance window. Coordinate with operations to schedule the swap during a planned shutdown. TOPNLMS recommends a concurrent DSBAT115 battery module replacement to eliminate the risk of program loss. Total swap time for an experienced engineer is typically under 30 minutes for a like-for-like replacement.

Q: Is the DSMB116 compatible with the DSPU110 as well as the DSPU116?
A: Compatibility depends on the specific firmware revision and sub-rack configuration. The DSMB116 5736 0001-EB is primarily documented for use with the DSPU116 processor. Compatibility with DSPU110 should be verified against the ABB Advant Controller hardware manual for your specific system revision before ordering.

Warranty Assurance

Every DSMB116 5736 0001-EB unit supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each module undergoes functional verification including power-on self-test validation and visual inspection for component integrity.
