What Data for This Category Looks Like
Data for this category originates from formulation and process libraries, raw material batch records, reactor DCS systems, weighing systems, LIMS, and warehouse systems of coating, resin, additive, agrochemical intermediate, and specialty chemical enterprises. Daily documents include batch production instructions, feeding review sheets, reaction process records, cleaning records, inspection reports, deviation and change orders. Data is updated per production batch and each critical step. It exhibits characteristics of multiple products and multi-step batch switching. It balances formula confidentiality requirements and confirmation of cleaning residues during product switching.
Constraints for Workflow Orchestration
Batch-level data from multiple sources requires workflows to integrate variables from disparate systems, and support triggering data pulls based on production nodes. The batch-update pattern requires workflow execution cycles to align with production cycles to avoid mixing cross-batch data. Multi-product switching scenarios require conditional branch nodes to be configured. These nodes check cleaning records and residue test results to prevent cross-contamination. Formula confidentiality rules restrict access to variables in workflows, only allowing authorized process personnel to view core formula fields. Multi-step feeding review processes require nodes to be arranged in sequence, to ensure raw material batch verification, feeding amount verification, and other links are completed in order.
Configuration Guidelines
All configurations below are set based on FastGPT v4.17.0.
| Configuration Item | Recommended Approach | Basis for This Approach |
|---|---|---|
| Prompt template | Must include fixed wording for feeding parameter verification, reaction end point judgment, and cleaning confirmation, compatible with full-width and half-width spaces | Matches the core business links of this category, solves parameter identification issues |
| Node trigger condition | Bind triggers by production batch nodeId | Ensures each production batch corresponds to a unique workflow instance, avoiding data conflicts |
| Variable mapping rule | Map LIMS test results, DCS reaction data, and warehouse raw material information to workflow variables | Integrates batch-level data from multiple systems to meet process review requirements |
| Timeout setting | 600 seconds | Matches the average time required for a single critical production step in this category |
| Error retry count | 2 times | Addresses temporary network fluctuations or short system freezes, avoiding process interruptions |
| Feishu multidimensional spreadsheet interface configuration | Use the Feishu Open Platform batch update interface, carry valid application credentials in the request header | Solves common issues with cross-system data writing, matches actual user operation scenarios |
Three Common Misconfigurations
- The workflow stops at a certain node without error logs. The cause is that the trigger is not bound by production batch
nodeId, and cross-batchvariablesconflicts cause the process to terminate silently. - The prompt fails to correctly identify spaces in feeding parameters, leading to failure of the verification link. The cause is that the rule compatible with full-width and half-width spaces is not configured in the prompt template, and only fixed formats without spaces are matched.
- Calling the Feishu multidimensional spreadsheet interface returns a Premature close error. The cause is that a reasonable timeout parameter is not set, or the request body carries sensitive formula fields that are not authorized, causing the connection to disconnect early.
How to Verify Successful Configuration
- Manually trigger the workflow for the corresponding batch, check whether raw material batch, reactor parameters, and other data are correctly pulled into
variables. - Input feeding parameters containing full-width and half-width spaces, verify that the prompt can correctly identify and complete the verification.
- Call the Feishu multidimensional spreadsheet interface, check whether the return status code is 200 and that the data has been correctly written to the spreadsheet.
- Simulate a production deviation scenario, verify that the conditional branch node can correctly trigger the deviation handling process.
