IoT Communication Development
Connect equipment electrical interfaces, communication protocols and network services to complete message parsing, message conversion, connection recovery and two-way data integration testing.
Development Scope
Connect equipment electrical interfaces, communication protocols and network services to complete message parsing, message conversion, connection recovery and two-way data integration testing.
RS-485, CAN and Ethernet Communication Board Development
Add communication interfaces to existing controller boards, including transceivers, isolation, protection, drivers and board-to-board integration testing.
Explore Scope and Deliverables →Communication Protocols and Wireless ConnectivityModbus RTU and TCP Protocol Development
Implement register reads and writes, data conversion, exception codes and timeout handling from the register specification.
Explore Scope and Deliverables →Edge Gateways and Existing Equipment IntegrationModbus-to-MQTT Protocol Gateway Development
Map registers to platform fields, MQTT topics and commands, including polling, write results and exception handling.
Explore Scope and Deliverables →Project Inputs
Information is used to determine interfaces, implementation conditions, and scope of work.
- Existing motherboard interfaces, voltages, connectors and space dimensions
- Modbus register table, device address and function code
- Register table, device address, connection parameters and polling cycle
Deliverables and Acceptance
- Delivery Documentation
- Communication board design data, firmware and interface test records, protocol code, register mapping, message samples and test records, conversion procedures, 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 pin definitions, logic levels and transmit and receive timings
- Check registers, numerical conversions, and reading and writing results item by item
- Check register to platform field conversion
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
Can I delegate only one of the development modules?
Yes. RS-485, CAN and Ethernet Communication Board Development, Modbus RTU and TCP Protocol Development, Modbus-to-MQTT Protocol Gateway Development can be scoped separately. Define the interfaces and integration responsibilities between modules before development.
Does adding a communication board require changes to the main board?
An add-on board can be evaluated when interfaces, power capacity and mounting space are available. Otherwise, the main-board interface or mechanical design may need changes. Schematics and prototypes establish the modification scope first.
