Data viewing and data analysis can be performed using Microsoft Excel software or a plain text editor. The data records will be stored in the built-in microSD memory card in CSV file format and can be downloaded to the computer through the built-in web interface.

Each data can contain up to 120 parameters. The MDCL-705i uses a periodic method to record user-specified Modbus register data. This allows devices such as PLCs to communicate to devices such as sensors, meters and instruments.

Modbus serial servers from B+B SmartWorx enable smooth connectivity by translating Modbus/TCP to Modbus/ASCII/RTU protocols. By this way it not only makes the data on the RS-485 being able to be shared with multiple Modbus TCP masters but also shorten the time to read data from multiple Modbus RTU slave devices. When communicating with Modbus via serial and Ethernet networks, a communication gateway is a necessity. And it accepts up to 8 Modbus TCP masters to read data from the Modbus registers directly instead of polling each Modbus RTU slave device one by one. It mirrors the data of the slave devices to its own Modbus registers. The MDCL-705i performs the pre-defined Modbus RTU commands to read data from the Modbus RTU slave devices via the RS-485. In this way, conventional devices can be connected to a modern control system and makes it easy to communicate with most SCADA / HMI system and PLCs through the Modbus TCP protocol. The MDCL-705i is used to collect and store data from multiple Modbus slave devices over the serial communication interface and make the data available to back-end management system via Ethernet communication.

With 2 Ethernet ports, the GW-2200 allows daisy chain connection which permits the flexibility in locating devices, eases installation and lowers infrastructure costs.

In addition, the GW-2200 series (for i version) also adds 3000 VDC isolation and +/-4 kV ESD protection component that diverts the potentially damaging charge away from sensitive circuit to protects the module and equipment from the sudden and momentary electric current. The dual watchdog is an important feature that ensures the module operates continuously, even in harsh environments. The CPU watchdog automatically resets the CPU if the built-in firmware is operating abnormally, while the host watchdog automatically resets the CPU if there is no communication between the module and the host (PC or PLC) for a predefined period of time (system timeout). The module contains a dual watchdog, including a CPU watchdog (for hardware functions) and a host watchdog (for software functions).

The GW-2200 module features a powerful 32-bit MCU to enable efficient handling of network traffic, and also has a built-in web server that provides an intuitive web management interface that allows users to modify the configuration of the module, including the DHCP/Static IP, the gateway/mask settings and the serial port settings. This feature dramatically reduces the loading on the RS-485 bus communication, ensures faster TCP responses, and improves the stability of the entire system. When other HMI/SCADA master controllers send the same requests to the same RTU slave device, the cached response is returned immediately. Moxa MGate protocol gateways support an easy.

The read-cache function is used to store previous requests and responses in the memory buffer of the GW-2200 module. This video provides an example of how to convert Modbus RTU to PROFINET protocol with Moxa’s MGate 5103 Series. The module can be used to create a pair-connection application (as well as serial-bridge or serial-tunnel application), and can then route data over TCP/IP between two serial Modbus RTU/ASCII devices, which is useful when connecting mainframe computers, servers or other serial devices that use Modbus RTU/ASCII protocols and do not themselves have Ethernet capability. The GW-2200 is a Modbus TCP to RTU/ASCII gateway that enables a Modbus/TCP host to communicate with serial Modbus RTU/ASCII devices through an Ethernet network, and eliminates the cable length limitation of legacy serial communication devices.
