SLE Wireless RS485 DTU Adaptation | Obeita
Delivered project. The completed hardware and software met the customer’s agreed requirements in testing. Specifications for a new project must be agreed separately.
Obeita delivered an SLE wireless RS485 DTU adaptation project, taking customer requirements through contract confirmation, hardware and software design, physical testing and delivery. The integration focus was the connection between an existing RS485 host and remote device links using a defined wireless bridge configuration.
Preserving the serial application’s meaning
The documented architecture places a master-side DTU at the PLC or host and remote DTU nodes at field interfaces. Obeita completed the agreed bridge hardware and software scope. A useful bridge design needs to retain device addressing and align the radio data path with serial-message boundaries, host timeouts and response behavior.
The public topology target is one master with multiple nodes; the listed upper node target remains subject to evaluation. It is not a published statement of the delivered node count. Packet length, polling interval and device timing determine how a particular installation can use the topology.
Roles and configuration across the bridge
The documented configuration scope covers master/node role, serial parameters, target identity and communication mode. Host and mobile configuration approaches appear as design concepts. For an export-facing configuration tool, an English interface is part of the new-project requirements alongside a maintainable provisioning route. A maintainable implementation needs an agreed provisioning route and a way to handle nodes that do not apply new settings; their appearance in the architecture does not establish that every tool option was delivered.
For a similar project, wireless propagation of settings should be defined together with acknowledgement and recovery behavior. Device protocols also need explicit attention to turnaround, inter-frame timing and broadcasts when the wired link is adapted to a radio path.
DTU installation and antenna choices
The hardware direction uses a 35 mm DIN-rail enclosure and an external antenna. Stub and remotely mounted antennas have different clearance and cable-routing requirements. Finished-DTU power requirements must be distinguished from values that refer only to the internal radio module. The public material leaves final assembly rating and site performance qualified for that reason.
Documented architecture and configuration
This table records the project’s documented architecture and selection boundaries. Options, variants and design inputs remain qualified as shown; their inclusion here is not an independent guarantee that every option formed part of the delivered configuration.
| Item | Configuration |
|---|---|
| Wireless direction | Hi3863 / SLE 1.0 |
| Field interface | RS485 |
| Topology target | One master; up to 8 nodes to be evaluated |
| Mounting | 35 mm DIN rail |
| Configuration scope | Role, serial parameters, node identity and mode |
| Power / range | Final assembly rating and site performance to confirm |
Delivered bridge and test boundary
The customer received the agreed SLE wireless RS485 DTU hardware and software implementation. Obeita completed physical testing, and the tested functions met the customer’s requirements before delivery. This confirms the project outcome without asserting a universal protocol bridge, a fixed site distance or successful operation at the maximum illustrated node target.
New node layouts, serial devices and antenna installations need a test scope reflecting their actual message timing and physical setting. A prospective pilot should use the intended packet lengths and polling intervals, include missing or offline nodes, and assess response time, message loss and recovery after power cycling. An existing delivered case provides an engineering reference, while a new deployment needs its own configuration definition.
