Engineering position
Wireless RS485 gateway for the industrial data layer
The product belongs to the acquisition and information layer: it records, converts, exchanges or publishes process and machine data. Deterministic machine or process control remains in the controller; logging, remote I/O and IIoT functions should be designed as a separate information path. Wireless gateway for extending Modbus RTU/RS485 communication across locations where new serial cabling is impractical.
Field-data integrationDefine field signals, channel count, acquisition purpose and the receiving PLC/SCADA/MES/cloud system.
Commissioning and diagnosticsProvide software access, network settings, firmware baseline and a repeatable commissioning procedure.
Documented protocol operationConfirm protocol role, addressing, network topology, security and data ownership for the selected model.
Current product position: Current AirGate Modbus positioning is wireless extension of Modbus RTU/RS485 networks using NOVUS-Air, with configurable topology and AES-CBC-128 data protection.
System role
AirGate Modbus signal and system architecture
The architecture separates the field/process interface, the NOVUS function and the downstream control or information path. Exact electrical interfaces, protocol roles and accessories remain model-dependent.

Application scope
AirGate Modbus application environments
These application classes indicate the engineering context. Final selection still depends on the exact range, I/O, communication, installation and performance requirements.
Distributed Modbus networks
For distributed modbus networks, define the source signals, acquisition rate, record-retention requirement and destination system before selecting the communication and storage architecture.
Remote instrument connection
For remote instrument connection, define the source signals, acquisition rate, record-retention requirement and destination system before selecting the communication and storage architecture.
