Modbus protocol is a common connection method between serial port devices in industrial field,and there are many kinds of protocols based on different connections,among which the most common are serial port Modbus(RTU/ASCII)and Ethernet Modbus TCP.In the actual industrial field,there are many applications that need to convert between the two protocols of Modbus.Traditional equipment such as instruments mostly use Modbus RTU,while the SCADA system mostly uses Modbus TCP protocol.Therefore,when integrating the data of traditional equipment into the SCADA system,the conversion protocol is usually required.To ensure smooth daily operation,engineers must find a solution to simplify complex Modbus protocol conversion.
MaxGate300 series gateway is a new industrial Modbus gateway with redundancy function launched by Maiwei Communication.It can realize the conversion between Modbus RTU/ASCII and Modbus TCP protocol.This series has two types of products,MaxGate300-8D232 and MaxGate300-8D485,which support 8-way RS232 or RS485 serial port to 2-way 10/100Base-T(X)adaptive Ethernet interface,and can meet the requirements of different application sites.
Basic functions
Dual Ethernet cascade cabling is simpler
Two 10/100M adaptive Ethernet interfaces.One port can be connected to the network or server,and the other port can be connected to another Ethernet device.The dual Ethernet ports make the device not need to be connected to different Ethernet switches separately,thus reducing the wiring cost.At the same time,it supports independent network segments and cascades.The dual Ethernet ports cascade well.
High performance protection against changing environment
The Cortex-A7 core is adopted,the operating frequency is up to 792MHz,the metal shell design,the industrial temperature is-40℃~85℃,the DC12~48V dual power supply redundancy,with high level of EMC protection,seismic resistance and impact resistance,and easy to cope with the harsh and changeable working environment.
Large expansion space for intelligent configuration-free
Modbus intelligent configuration-free pre-reading,single serial port supports 256 Modbus RTU instructions;It supports receiving access to a maximum of 256 Modbus TCP client(master)devices and connecting 128 Modbus TCP server(slave)devices.The number of connections can be synchronously extended to other pass-through modes.Support virtual ID and real ID mapping to realize flexible access between master and slave devices.
High compatibility,strong transmission and good stability
In addition to the normal pass-through function,it supports Httpd Client,WebSocket Client and other functions.It can choose any of 15 working modes.It has rich software functions and strong pass-through forwarding performance.Support the functions of customized registration package and heartbeat package,RFC2217 protocol,NTP synchronization time,and restart of devices without data.
Industry application
The MaxGate300 series industrial Modbus gateway of Maiwei Communication is powerful,easy to expand,and easy to install.It can be widely used in industrial automation,intelligent power,intelligent transportation,safe city,petrochemical and other industries.
