What data for this category looks like
Data for this category comes from multiple business systems of enterprises in the coatings, resins, additives, agrochemical intermediates and specialty chemicals sectors. It includes documents such as batch production instructions, feeding review sheets, reaction process records, site cleaning records, inspection reports, deviation and change orders. Data sources include formula and process libraries, raw material batch ledgers, reactor DCS systems, weighing systems, LIMS laboratory information management systems, and warehouse management systems. Data updates are triggered once per production batch or each key process step. Single-batch documents contain standardized fields with units: feeding amount (unit kg), reaction temperature (unit ℃), reaction duration (unit hours), inspection result values, and other similar fields.
What constraints do these characteristics impose on HTTP interfaces and external systems
The batch-by-batch and key-step update pattern of this category’s data requires HTTP interfaces to support precise data pulling by batch ID or process step timestamp. The need to connect with multiple external systems from different sources requires interface configurations to support concurrent calls to multiple endpoints. The requirement that standardized fields include units requires interfaces to retain unit information for fields during transmission, to avoid data parsing deviations. The high-frequency update characteristic requires interfaces to set reasonable timeout and retry mechanisms. This prevents reaction out of control, batch non-conformity or cross-contamination caused by system response delays or data pulling errors. Due to the confidentiality of formula and process data, interface authentication must strictly distinguish application permission scopes.
How to configure
| Configuration Item | Recommended Approach | Rationale |
|---|---|---|
Authorization | Application-specific key, generated separately per production batch | Matches the data confidentiality requirements of fine chemicals, prevents core process and formula information from being leaked via universal keys |
variables | Pass batch ID, process step timestamp | Enables precise pulling of document data for the corresponding batch or step, adapts to the batch-by-batch update characteristic of this category |
responseData | Retain original fields and unit information | Meets the requirement for standardized fields with units in documents of this category, avoids data parsing deviations |
| Interface timeout setting | 600 seconds | Addresses response delays from industrial systems such as reactor DCS, reserves sufficient time for data pulling |
| Retry mechanism configuration | Retry 2 times after failure, 30-second interval | Addresses occasional network fluctuations in industrial systems, ensures data pulling success rate |
| Multi-system authentication configuration | Configure secrets separately for each external system | Connects to multiple data sources such as LIMS and warehouse systems, achieves permission isolation |
This configuration is based on FastGPT v4.17.0
Three common configuration errors
- Symptom: 403 permission denied error returned when calling
api/v1/chat/completions. Cause: Universal key was used, and exclusive application permissions were not configured for fine chemical batch data. - Symptom: Some fields are empty when importing LIMS data via
api/core/datas. Cause: Standardized fields for documents of this category were not matched, and unit-including field information such as feeding amount and reaction temperature was not passed. - Symptom: Batch data audit process cannot be triggered after calling the workflow creation interface. Cause: Node parameters triggered by batch ID were not configured, and the step-by-step update data rhythm of this category was not adapted.
How to verify correct configuration
- Call the
api/v1/chat/completionsinterface, with the application-specific key and batch ID variable passed, check that the returned result includes the content of the corresponding feeding review sheet. - Call the
api/core/datasinterface to import LIMS inspection data, check thatresponseDataretains the numerical value and unit of the inspection result. - Simulate network fluctuations in industrial systems, trigger interface call failure, check that the retry mechanism is executed as configured.
- View interface logs, confirm that each call only pulls document data for the current batch, and no irrelevant content is returned across batches.
