Modbus-to-MQTT Protocol Gateway Development
Map registers to platform fields, MQTT topics and commands, including polling, write results and exception handling. For integrators and equipment manufacturers who need to connect industrial instruments to the cloud.
Development Scope
Map registers to platform fields, MQTT topics and commands, including polling, write results and exception handling.
- Who This Service Is For
- Integrators and equipment manufacturers who need to connect industrial instruments to the cloud
- Deliverables to Agree
- Conversion program, mapping configuration and device to platform integration testing records.
Project Inputs
Information is used to determine interfaces, implementation conditions, and scope of work.
- Register table, device address, connection parameters and polling cycle
- MQTT Topics, message formats, authentication and device models
- Command writing, response, caching and alarm rules
Deliverables and Acceptance
- Delivery Documentation
- Conversion program, mapping configuration and device to platform integration testing records.
- Versions and Reproducibility
- The delivery list records the target hardware, software version, build or deployment steps, interface configuration and test records to facilitate subsequent integration testing and maintenance.
- Check register to platform field conversion
- Check command writing and actual device status feedback
- Test equipment offline, platform offline and recovery and resumable data upload
The acceptance is carried out based on the equipment, version, environment, samples and indicators confirmed by both parties; the scope of source code and design documents, prototype materials, third-party fees and subsequent maintenance are listed in the project documents.
Frequently Asked Questions
How is execution of a platform command confirmed at the device?
Record platform receipt, bus write and device feedback separately. Commands requiring confirmation use status readback or the agreed acknowledgment as execution evidence. Successful MQTT transmission alone is not proof of execution.
What information is required to determine the scope of development?
Please provide: Register table, device address, connection parameters and polling cycle; MQTT Topics, message formats, authentication and device models; Command writing, response, caching and alarm rules. Missing information can be addressed through interface checks or a focused feasibility test before the scope is agreed.
