FAQ
Ask Us Anything
Q1: What is an Industrial RTU Gateway?
A1: An Industrial RTU Gateway (Remote Terminal Unit Gateway) is a field communication device used to collect data from PLCs, sensors, meters, and industrial equipment, then transmit the data to SCADA systems, cloud platforms, or control centers. Unlike traditional RTUs with fixed functions, IOTRouter industrial RTU gateways combine data acquisition, protocol conversion, edge logic, and remote communication in one device. They are widely used for industrial monitoring, power systems, water treatment, energy management, and automation projects.
Q2: Does the RTU gateway support Modbus RTU and RS485 communication?
A2: Yes. IOTRouter RTU gateways support Modbus RTU over RS485 as well as Modbus TCP over Ethernet. Multiple RS485 interfaces allow connection with field devices such as: energy meters PLCs sensors frequency converters water pumps industrial instruments The collected data can be converted to MQTT, HTTP, TCP, IEC104, or other protocols for SCADA and cloud integration.
Q3: Does the industrial RTU support remote communication via 4G LTE, Ethernet, and Wi-Fi?
A3: Most models support LTE 4G and wired Ethernet. Select advanced models offer Wi-Fi 6 or 5G connectivity. You can choose the communication link that best fits your deployment environment.
Q4: What applications can use an industrial RTU gateway?
A4: Industrial RTU gateways are commonly used in:
- Power monitoring and substations
- Water and wastewater pump stations
- Energy management systems
- Solar and renewable energy monitoring
- Factory automation
- Building automation systems
They provide remote data acquisition and communication for distributed industrial sites.
Q5: Can the RTU gateway perform edge logic and local automation?
A5: Yes. Our core products fully support Nó-vermelho as a logic orchestration engine. No low-level coding required — you can implement edge-side logic control and data processing quickly through a drag-and-drop flow editor.
Q6: Do your industrial RTU gateways have RS485, RS232, CAN, DI, DO, AI, AO, and LAN interfaces?
A6: Yes, but the exact interface configuration depends on the model. For example:
- Our I/O Industrial Controller provides 4×RS485, 2×DI, 2×DO, 1×USB 2.0, 2×LAN, and expandable I/O interfaces.
- Our Multi-interface ARM Industrial PC provides 2×RS485, 1×RS232, 2×CAN, 2×DI, 2×DO, 1×LAN, 2×USB 2.0, and 1×HDMI.
Q7: Does the industrial RTU gateway support remote operations and debugging?
A7: Yes. Our remote operations platform lets you manage devices remotely — cutting travel costs and boosting maintenance efficiency.
- Remote Deployment & Configuration: After on-site installation, all config changes, logic adjustments, and programming can be done remotely.
- Agile Response: Update RTU logic from the backend anytime to adapt to changing production needs.
- Efficient Fault Diagnosis: Engineers can remotely debug and pinpoint issues directly, significantly reducing downtime.
