Scenario development scope
Field devices and terminals
Focus on 4G industrial DTU development, 4G PLC data acquisition gateway development and other products to clarify the interface, power supply and installation conditions, and develop or transform terminals.
Business and data
Define data, events, commands and results according to the device and controller → collection or routing gateway → 4G link → enterprise platform → after-sales and operation and maintenance, and retain the association between devices, sites or projects.
Platform and operation and maintenance
Connect with existing enterprise platforms, or develop device management, historical data, alarms, permissions and client functions, and determine the scope by module.
system constraints
In the planning stage, check the original control responsibilities, equipment protocol authorization, on-site network and remote operation permissions, and clarify the responsibilities and exception handling of local and remote systems.
product development services
Select corresponding technical services based on field equipment and target business. You can start with a single terminal or combine multiple device types. The following products describe the interfaces, business processes, delivery materials and acceptance methods respectively.

Equipment and controller → Collection or routing gateway → 4G link → Enterprise platform → After-sales and operation and maintenance.
The platform manages devices according to enterprise projects, sites and permissions. After the link is restored, check the data and service status; when control is involved, separately confirm command authority, timeliness, local conditions and execution feedback.
Project Inputs
- Target business, equipment list, on-site location, equipment size and users.
- Wiring, protocols, raw data and open software interfaces to existing equipment.
- Key points to confirm: original control responsibilities, equipment protocol authorization, on-site network and remote operation permissions.
- Platform status, data retention, client and deployment methods, prototype and on-site verification conditions.
Deliverables and Acceptance
| stage | Delivery content | Verification basis |
|---|---|---|
| Needs and plans | Equipment interface list, business process, system architecture and development division of labor | Check original control responsibilities, equipment protocol authorization, on-site network and remote operation permissions. |
| Development and integration testing | Agree on terminal hardware, firmware, interfaces and platform applications | Check the fields, status, instructions and abnormal behaviors one by one according to the actual device. |
| Acceptance and handover | Prototype or program, design and deployment data, test records and version list | Accept according to the agreed environment, sample, duration and threshold, and record the handling of failed items. |
R&D, prototype materials, structure, testing, on-site implementation and subsequent operation and maintenance are listed separately. Project cost and cycle are evaluated based on equipment type, interface complexity, existing foundation and verification workload.

View Development Scope and Deliverables →Frequently Asked Questions
Can I access one type of equipment first and then expand to more models?+
You can first establish the data model, access method and acceptance use case with the target model and point table. Subsequent models will be expanded according to protocol differences, and will verify fields, polling and exception recovery respectively.
Can I reuse existing platforms and terminals?+
You can first check the existing interfaces, data and code, and focus new development on the missing links. In this scenario, it is necessary to focus on checking the original control responsibilities, equipment protocol authorization, on-site network and remote operation permissions, and then determine the reusable scope and return work.
