Dahua Technology SMT Material List and MES Data Collaboration Project

Addressing Dahua Technology's business needs for SMT production readiness and data collaboration, Hegong Software took the consistency of programs, materials, and feeder slots emphasized by the RockPlus PVT Process Error-Proofing and Traceability System as the entry point, and, building on the customer's existing Siemens SIPLACE Pro and MES environment, custom-developed the LLE application to construct a collaborative process from placement engineering data to production material-preparation data.

1. Connecting SIPLACE Pro to automatically generate standardized SMT material lists

Through the SIPLACE Pro interface, the system reads Job, Recipe, and Setup data, extracts lines, equipment, feeder slots, Feeders, components, placement designators, and placement quantities according to production tasks and placement programs, and automatically organizes them into the GF (Setup List, i.e., the loading list).

Engineers can select the loading plan to output by Job or Recipe, preview the material list, and adjust fields, formats, and pagination through configurable Excel templates. The generated lists support Excel export and printing, convenient for line operators and warehouse material-preparation staff to use.

For key components, the list can additionally display package outline reference drawings, angle and polarity-related information generated from SIPLACE Pro component data, assisting on-site loading verification.

2. Establishing a BOM difference verification mechanism to identify material inconsistencies in advance

The system supports importing product BOMs via Excel and comparing BOM part numbers and placement designators against the actually generated placement material lists, automatically outputting a difference report.

Per Dahua's business requirements, the project provides TOP/BOT material addition and deletion difference lists by board side, and also generates material-missing reports for the list, helping engineers quickly locate differences between the BOM and the placement program.

The system can also import work orders, substitute materials, and component moisture sensitivity level information, supplementing substitute part numbers, moisture sensitivity grades and other content when generating the list, reducing duplicated manual maintenance and improving the completeness of material-preparation documentation.

3. Unifying feeder slot data as a foundation for RockPlus PVT placement process verification

In the placement process, consistency among programs, BOMs, Setups, and feeder slot positions is an important prerequisite for preventing wrong materials, wrong positions, and wrong programs.

The project transforms production programs and loading plans in SIPLACE Pro into structured GF data, preserving the correspondences among Job, Recipe, line, machine, feeder slot, Feeder, and material, and supporting batch synchronization by designated program groups, updates by individual Job, and conditional queries.

This standardized data echoes RockPlus PVT's program, BOM, and Setup verification capabilities for placement workstations, providing a consistent data basis for further workstation-level material verification, production process recording, and exception traceability.

4. Connecting Dahua's MES to link engineering material lists with warehouse material preparation

The project integrates the feeder slot list upload function with Dahua's existing MES. After engineers generate and confirm the material list, they can enter the work order number, target production quantity, PCB part number, and board side, writing the feeder slot master data and its details into the MES.

The uploaded details contain the equipment, feeder slot position, component part number, Feeder type, placement designator, and required quantity needed for material preparation, and the system identifies and gives prompts on duplicated work-order slot lists.

This forms the data hand-off flow of SIPLACE Pro engineering data → LLE material list processing → MES feeder slot list → warehouse material preparation, reducing duplicated organization and information transmission between the engineering side and the production management system.

5. Synchronizing CycleTime and CPH to complete placement efficiency data management

Beyond material and feeder slot data, the system can also synchronize CycleTime, ProductionTime, CPH, placement point counts, and panelization information for Recipes from SIPLACE Pro, supporting addition, change, and full-synchronization modes.

The project provides takt query reports comparing by product, board side, and different production lines, with Excel export supported, helping engineering and production managers more conveniently view post-optimization placement efficiency data and providing a basis for line configuration, production readiness, and takt analysis.
