Sepehr Modbus Gateway

Sepehr Modbus Gateway represents an innovative solution in the Industrial Internet of
Things (IoT) domain, designed to aggregate data from industrial machinery and environmental
monitoring sensors. It securely transmits this data to customized SCADA systems or advanced
monitoring platforms via a standard LAN connection utilizing the SNMPv3 protocol. Within the
system architecture, the Modbus protocol is exclusively employed to facilitate
communication between sensing and measurement devices and the central Modbus gateway.

Features of Sepehr Modbus Gateway

•  Supporting up to 30 Sepehr Modbus devices through both RTU and TCP protocols
• Reduces cabling requirements through BUS topology
• Streamlined installation, suitable for large industrial settings.
• Simple configuration using a single IP address for up to 30 sensors
• SMS backup mode for instant alerts in case of power or network failure
• Supports cable lengths of up to 1 km
• Built-in web interface for easy sensor setup
• High-speed and stable performance, even in wide industrial networks
• Continuous software updates and technical support

Sepehr Modbus Gateway Specifications

• Two RJ12 sockets or one 4-pin Phoenix connector (configurable based on user
requirements)
• 12V DC power input
• Integrated Under-Voltage Lockout (UVLO) technology to extend battery lifespan
• Utilizes SNMPv3 protocol with Trap functionality for secure and reliable data
transmission
• Optional backup battery support to ensure continuous operation during power failures

What is Modbus and How Does it Work?

In the Master/Slave Modbus protocol, data is organized and transmitted in tables, where only
the Master device (the gateway) initiates requests for data from Slave devices (such as Sepehr
environmental sensors). Consequently, Slave devices cannot transmit data independently
without explicit permission from the Master. The most widely used types of this protocol are
Modbus RTU and TCP, where a single Master gateway communicates with multiple Slave devices
configured in a bus topology network. In this arrangement, each device is connected
sequentially to its two adjacent devices, except for the devices positioned at the beginning and
end of the chain.

Within this framework, the Sepehr Modbus Gateway functions as the Master, while
environmental monitoring sensors and other industrial equipment act as Slaves. Each Slave
device is assigned a unique, configurable Slave ID—typically set manually via binary
switches. This identifier enables the Master to accurately recognize and associate the data
transmitted by each device, such as temperature measurements, with the corresponding Slave.

Enhancing Industrial Automation via the Modbus Gateway

The Sepehr Modbus Gateway is a robust and reliable device designed to collect data and
manage environmental conditions within industrial and sensitive environments. It supports
simultaneous data acquisition from up to 30 sensors monitoring parameters such as
temperature, humidity, water leakage, and power status, securely transmitting this information
to servers or specialized platforms like SCADA or the Sepehr Monitoring System.

Its straightforward installation process, streamlined wiring requirements, and extensive
coverage make this gateway a perfect approach for applications including manufacturing
plants, server rooms, data centers, large-scale greenhouses, cold storage facilities, industrial
warehouses, power generation stations, and telecommunication infrastructure.

With real-time SMS notifications and secure data transmission, the system enables continuous
awareness of any operational anomalies or disruptions.
