Modbus Gateway Device FAQs

With Modbus gateways, non-Modbus devices can be connected to a Modbus network or the other way around. Another use for a Modbus gateway is to remap registers so that a new Modbus slave can mimic an older Modbus slave. Translating Modbus RTU to Modbus TCP or vice versa is also a common application of a Modbus gateway. Learn More about What is Modbus gateway in detail.

Using the Modbus TCP protocol, a IoT Modbus gateway converts serial devices into TCP packets for communication. It enables you to connect your smart meters, PLCs, and other devices that use Modbus RTU serial communication to the Modbus TCP protocol, which then enables communication over the ethernet network.

Modbus TCP/IP (also known as Modbus-TCP) consists simply of the Modbus RTU protocol with an Ethernet-based TCP interface. Independent of the data transmission medium, the Modbus messaging structure is the application protocol that establishes the principles for assembling and interpreting the data.

To communicate data between industrial devices, Modbus is a straightforward and frequently used industrial communication protocol. It is simpler to connect devices over longer distances or to connect to devices over a network because Modbus TCP/IP allows Modbus devices to communicate over Ethernet.

Dusun IOT Modbus Gateways support MQTT and Pre-Built 3 rd Platform (such as Thingsboard). You can easily retrieve Modbus data from other devices and make this available to a local visualization or an MQTT cloud service.

The industrial automation and control industry often uses Modbus, a serial communication protocol on the application layer, to send data between electronic equipment. An additional layer called Wireless Modbus makes it possible for Modbus devices to communicate wirelessly.

Modbus comes in two different types: RTU and TCP/IP. These are really just two distinct methods of data transmission. RTU and TCP/IP encapsulate the structured data for the particular transmission techniques, whereas Modbus specifies how the data is formatted for transmission.

RS-232 and RS-485 are the two different serial protocols for Modbus. The concurrent, full-duplex flow of data is supported by Modbus RS-232. Half-duplex Modbus RS-485 uses voltage differences to indicate values.

Modbus messages can be transmitted through Ethernet or TCP/IP as well. These Modbus communications are packed in 16-bit word packets or single bit packets.

Yes. We have LoRa Modbus bridge gateway that allows users to locally collect data on any sensor and centralizes information with a complete system overview displayed in user consoles, or it can also be redirected to the preferred supervision system, such as SCADA.
