This configuration guide applies to FastGPT v4.17.0.
Data Profile for This Category
Data for this category comes from customer manuscripts, color management systems, printing press operating data, ink and substrate batch records, spectrometers, and barcode detectors. Daily generated documents include pre-press files, imposition sheets, printing process sheets, ink color matching records, first article sample approval reports, barcode inspection records, and die-cutting and lamination ledgers. Data updates trigger with each order, each production batch, and each plate change. Core fields include plate number, color parameter values, barcode verification results, and substrate batch numbers. Field units adjust dynamically based on document type.
Constraints for Workflow Orchestration
High-frequency data updates with scattered trigger points require workflows to support production event-based triggering. Standardize formatting for multi-source heterogeneous data across all nodes. Configure dynamic variable rules to adapt to field differences across different document types. Require manual review for first article sample approval and barcode inspection links. Reserve node positions for inserting manual approvals. Obtain equipment data from printing presses, spectrometers, and other devices via external interfaces. Reserve external plugin access ports. Configure verification nodes at key links to intercept abnormal data early, as errors including typos, incorrect plate versions, and unreadable barcodes can lead to full batch scrap.
Configuration Settings
| Configuration Item | Recommended Setting | Rationale for This Setting |
|---|---|---|
| Trigger method | Bind plate change and batch material change events | Align with the feature of this category updating data based on production events |
| Global variable mapping | Enable variables dynamic field rules | Adapt to field differences across multiple document types such as pre-press files and process sheets |
| External plugin access | Configure standard MCP interface | Access detection data from spectrometers and barcode detectors |
| Code run node timeout | Set to 300 seconds | Avoid long-running format conversion tasks blocking the workflow |
| Variable reference scope | Enable global variable optional value display | Cover field call requirements across different document types |
| Workflow node identifier | Record nodeId unique identifier | Enable precise subsequent calls to workflow nodes |
Common Misconfigurations
- Fail to synchronize detection data after configuring an external MCP plugin. The cause is unconfigured interface parameters per plugin specifications, which blocks workflow nodes from accessing data from spectrometers and barcode detectors.
- Receive no return result after a code run node executes. The cause is unset reasonable timeout periods, which leads the system to forcibly terminate long-running color parameter conversion tasks.
- See no optional value list when referencing knowledge base variables. The cause is disabled optional value display configuration for global variables, which prevents the system from loading field parameters for corresponding documents.
How to Verify a Successful Configuration
- Trigger a simulated plate change event, and verify automatic workflow startup.
- Connect an external MCP plugin and push test data, and verify normal data reception by workflow nodes.
- Call the knowledge base variable reference function, and verify display of optional field values for corresponding documents.
- Use the recorded
nodeIdto initiate a workflow call, and verify return of correct execution results.
