What the data for this category looks like
Data comes from enterprise equipment management systems (EAM), dealer inventory ledgers, and sensor collection terminals deployed on-site. Basic equipment ledgers are updated monthly, including core parameters such as unique device ID, model, rated power (kW), maximum working pressure (MPa), and others. Real-time operating parameters are refreshed every 15 minutes, including dynamic fields such as current load, total operating hours (h), and others. Maintenance records are submitted by on-site engineers as needed, linked to corresponding device IDs. All data is in structured JSON format, with fields tightly bound to industrial measurement standards and no redundant nested structures.
What constraints these characteristics impose on forms and interactions
Dispersed data sources with significantly different update rhythms require forms to support multi-data-source linked loading, avoiding static caching that causes data lag. Most fields are bound to industrial standard units, so forms need built-in unit validation rules to automatically block inputs that do not meet measurement formats. Device ID is the unique core identifier, so forms must call interfaces in real time to check uniqueness before submission to avoid duplicate entries. Some fields have strong relational dependencies, so forms need to support linkage logic: selecting a device ID automatically pulls corresponding rated parameters to reduce manual input errors.
How to configure
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
form_field_unit_switch | Enabled, enable industrial unit presets | Specialized equipment form fields often carry industrial units such as kW and MPa. Enabling this allows automatic input format validation and unit conversion |
form_field_unique_check | Enabled, bound to device ID field | Device ID is the unique identifier. Real-time validation is required to avoid duplicate submissions, which aligns with the uniqueness management requirements of equipment ledgers |
form_dynamic_load_interval | 15 minutes | Real-time operating parameters are refreshed every 15 minutes. Setting this interval ensures that device data loaded by forms is synchronized with on-site data |
form_batch_import_limit | 50 items per batch | Specialized equipment maintenance records or batch configuration data should not be imported in too large a single batch to avoid interface timeouts, which aligns with the reasonable volume of industrial data submitted in a single batch |
form_field_validation_rule | Custom regular expression matching industrial unit formats | Ensure that input parameters such as power and pressure comply with industrial measurement standards and avoid invalid data submissions |
form_linkage_trigger | Triggered after selecting device ID | Automatically pull corresponding rated parameters after selecting a device ID to reduce manual input errors, relying on the strong relational characteristics of device fields |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis. It is recommended to test on your own samples before finalizing settings.
Three common errors
- Symptom: JSON input fields cannot select workflow variables, and fields are empty after submission. Cause: The
form_json_var_bindconfiguration item is not enabled, causing the JSON input field to only support static text input and cannot bind dynamic variables. - Symptom: 408 Request Timeout is returned after form submission. Cause: The
form_dynamic_load_intervalis set too short, frequent calls to the device data interface lead to interface current limiting and exceed the threshold. - Symptom: Some data is not parsed when batch importing maintenance records. Cause: The
form_batch_import_limitis set above a reasonable upper limit, exceeding the single-processing capability of the interface, and some data is truncated.
How to confirm configuration is complete
- Access the form editing page, select the JSON input field, verify if a variable selection pop-up displays, confirm the
form_json_var_bindconfiguration is enabled. - Select the device ID field, trigger the linkage dropdown, confirm that corresponding rated parameters are automatically pulled, verify the
form_linkage_triggerconfiguration is active. - Submit a single test data entry with industrial units, check for automatic system validation of unit formats and error prompts, confirm the
form_field_validation_ruleconfiguration is correctly set. - Import a batch of test data matching the volume specified in
form_batch_import_limit, confirm all entries are successfully parsed, verify the configuration aligns with actual requirements.
