Development Scope
Scope and Basic Check
Determine the existing foundation, technical dependencies and content that needs to be developed based on the register table, function code, address, byte order, magnification, serial port or TCP parameters and platform fields.
Implementation and integration
Develop device polling, register parsing, exception handling and platform mapping, and design read-only collection and authorized writing processes respectively.
Delivery Documentation
Deliver mapping tables, source code and message records.
Verification and Constraints
The polling cycle is related to device responsiveness and bus load; write permissions and production impact need to be confirmed separately.
Project implementation process
Verification of data and interfaces → Confirmation of technical solutions and verification use cases → Implementation of integration with the target environment → Regression of abnormal scenarios → Transfer of version data.
Verify the implementation results in the target hardware and software environment, and deliver records of associated interface configurations, version dependencies, and problem handling to facilitate subsequent integration and maintenance by the enterprise R&D team.
Project Inputs
- Register table, function code, address, byte order, magnification, serial port or TCP parameters and platform fields.
- Design information, code, interface permissions and target test equipment can be provided.
- Source files, programs or tools expected to be delivered, inter-module integration testing responsibilities and project nodes.
- Acceptance samples, environment, test conditions and passing thresholds.
Deliverables and Acceptance
| Deliverables | Delivery content | Verification method |
|---|---|---|
| achieve results | Deliver mapping tables, source code and message records. | Check the byte order of each type of field. |
| Integrated data | Versions and dependencies, interface configuration, usage or deployment steps, and integration changes | Test exception codes, timeouts and illegal addresses. |
| Verify records | Test conditions, execution records, problem lists and regression results | Verify multi-device polling and write result readback. |
The delivery scope and acceptance criteria are determined based on the target environment. Third-party SDK, licenses, laboratories, cloud resources, equipment materials and on-site support are listed separately; when the existing information is insufficient, follow-up work will be determined through interface verification or key function verification.
Frequently Asked Questions
Are reading deviations necessarily a sensor issue?+
First check the register offset, data type, byte order, scaling and unit, and then compare the original message with the device display. Normal link communication does not mean that the field interpretation is correct.
4G Modbus What information do I need to provide first for acquisition and protocol conversion development?+
Please give priority to the register table, function code, address, byte order, magnification, serial port or TCP parameters and platform fields. At the same time, the existing implementation, problems encountered, expected changes, and compatible test conditions are explained to facilitate the determination of implementation scope and reproduction methods.
Can it be implemented on existing products?+
You can first evaluate the scope of existing designs and versions that can be changed, retain the verified parts, and determine the interfaces and dependencies that need to be adjusted. This service requires attention: the polling cycle is related to device responsiveness and bus load; write permissions and production impact need to be confirmed separately. Existing and new functions must undergo regression testing within the agreed scope after the changes.
