ICP DAS USA 产品说明 - 工业级 Modbus 网关说明书

Industrial Modbus GatewayModbus is a standard industrial communication protocol, and is now the most commonly available means of connecting industrial electronic devices. Modbus allows for communication between many devices connected to the same RS-485 network, for example, a system that measures temperature and humidity and communicates the results to a computer. Modbus is often used to connect a supervisory computer with a remote terminal unit (RTU) in supervisory control and data acquisition (SCADA) systems.There are different version of the Modbus protocol for serial and Ethernet communication. Modbus RTU and ASCII are used in serial communication that makes use of ASCII characters for protocol communication. Modbus RTU is the most common implementation available for Modbus. Modbus TCP is used for communication over TCP/IP networks, connecting over port 502.The tGW-700 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. 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 new read-cache function is used to store previous requests and responses in the memory buffer of the tGW-700 module. When other HMI/SCADA master controllers send the same requests to the same RTU slave device, the cached response is returned immediately. This feature dramatically reduces the loading on the RS-485 bus communication, ensures faster TCP responses, and improves the stability of the entire system.DHCP minimizes configuration errors caused by manual IP address configuration, such as address conflicts caused by the assignment of an IP address to more than one computer or device at the same time. The tGW-700 module supports the DHCP client function, which allows it to easily obtain the necessary TCP/IP configuration information from a DHCP server. The module also contains a UDP responder that transmits its IP address information in response to a UDP search from the eSearch utility, making local management more efficient.The tGW-700 module also 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 theDHCP/Static IP, the gateway/mask settings and the serial port settings.The module contains a dual watchdog, including a CPU watchdog (for hardware functions) and a host watchdog (for software functions). 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 dual watchdog is an important feature that ensures the module operates continuously, even in harsh environments. In addition, the tGW-700 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 tGW-700 module offers true IEEE 802.3af-compliant (classification, Class 1) Power over Ethernet (PoE) functionality using a standard category 5 Ethernet cable to receive power from a PoE switch such as the NS-205PSE. If there is no PoE switch on site, the module will also accept power input from a DC adapter. The tGW-700 module is designed for ultra-low power consumption, reducing hidden costs from increasing fuel and electricity prices, especially when you have a large number of modules installed. Reducing the amount of electricity consumed by choosing energy-efficient equipment can have a positive impact on maintaining a green environment.The module is equipped with a male DB-9 or a removable terminal block connector to allow easy wiring. Based on an amazing tiny form-factor, the tGW-700 achieves maximum space savings that allows it to be easily installed anywhere, even directly embedded into a machine. It also supports automatic RS-485 direction control when sending and receiving data, thereby improving the stability of the RS-485 communication.tGW-700 series offers different combination of number of ports to select, including RS-232, RS-422, and RS-485 for your applications.If you have other industrial communication requirements or have questions, we can certainly help you to choose the best solution.

Gateway configuration...............................................................................................................................Step 1 ......................................................................................................................................................Step 2 : (6)Step 3 : (7)Step 4 : (8)Step 5 : (8)Subcribe and publish the MQTT topic associated with each Tag. (10)INTRODUCTIONThe AT-MQTT Gateway is Modbus RTU master to MQTT Converter.It allows to publish the data read from Modbus Slaves into MQTT Server.The gateway allows fast and easy access to IoT world and is compatible with IoT Servers that support MQTT protocol.Example of connection:AT- MQTT-GatewayCONFIGURATIONPrerequisitesBefore configuring communication parameters via Web Interface, you need to connect the gateway to internet network by wire or Wi-Fi connection. For changing IP of the gateway, kindly search on “how to change raspberry IP”.Gateway configurationYou need to access to web Interface (the server runs on your gateway) in order to perform the following:Define the parameter of MQTT.Define the parameter of Modbus RTU channel.Define which Modbus memory addresses sent to MQTT serverChange your account and password.Reboot the gateway to update your configuration.Step 1: Access Web interface with url: “IP:9000”, if you use default LAN IP, the url is “192.168.1.100:9000”.You are prompted to enter username and password. The default user name is “admin”,the default password is “admin”. Then click Login button and you will be logged into web interface:The page is divided in different sections in order to define the different parameters of the gateway:∙ModbusRTUCommunication∙MQTTCommunication∙Tags∙AccountStep 2:Define the parameter of Modbus channel.“Port Name”: the port name to use (/dev/tty/USB0)“Baud Rate”: the baud rate of the serial line.“Databits”: the data bits of the serial line.“Parity”: the parity of the serial line.“Stopbits”: the stop bits of the serial line.“Response Timeout”: the time out of the serial line.“Period”: the period is the Cycle of Modbus master-slave query-response.Click “Apply” to update your configuration.Step 3:Define the parameter of MQTTThe section is used to define the main parameters of MQTT. Meaning of each row:“MqttClient ID”: Mac address of your gateway and cannot be changed.“Server Url”: Url or the IP Address of the defined MQTT server.“Server Port”: the port used for defined MQTT communication.“Username”: the username for the connection to MQTT server.“Password”: the password for the connection to the MQTT server.“Clean Section”: if set to “True”, the last MQTT message is deleted by the server and the client in case of missing ACK. If it is set to “false”, theServer and the client hold the last MQTT messages and , in case ofincorrect disconnection or missing ACK, they try to send again since allthe ACK messages are exchanged correctly (valid only for Qos 1 and QoS2).“Keep Alive”: the delay which the keep alive message is sent on MQTT.“Retained”: if set to “true”, the retained flag is enabled. The MQTT server will hold the last topic published.“QoS”: the Qos level.Clic k “Apply” to update your configuration.Step 4: Define which Modbus memory addresses are sent to MQTT serverMeaning of each field:“Tag Name”: the name of tag. This name must be unique.“Slave Id”: the address of the Modbus device.“Type”: the data type of the Tag. It is possible to choose between the following :o Coil Statuso Input Statuso Holding Registero Input Register“Address”: the starting address of the Tag.“Number Point”: the number of consecutive points.Click “Add” to create new tag.Click “Edit” to redefine tag.Click “Delete” to delete tag.Step 5: After completely configure the Gateway, Log out of Web Interface and Reboot your Gateway.Subscribe and publish the MQTT topic associate with each Tag.Each Tag is sent by gateway to MQTT server by publishing to a MQTT topic. These topics have name in format: Mac address/slave Id/Tag Name.For writing value to each Tag, gateway subscribes to a MQTT topic. These topics have name in the format: Write/Mac address/slave Id/Tag Name.For Example: A gateway has Mac address is “B827EB087532”. If you define a Tag named “Tag 1”and your Modbus Slave ID is “1”, The value of Tag is published to topic name : “B827EB087532/1/Tag1 “ and subscribed to topic name: “Write/ B827EB087532/1/Tag1”.Data Format is in byte array: timestamp (8 byte), Value of Tag, Status (1 byte). The Status byte means: 1 is for good connection, 0 is for bad connection.Other MQTT clients read data of Tag by subscribing to the topic that gateway has published to MQTT server.Other MQTT clients write data to Tag by publishing value to Topic that gateway has subscribed. The Value is written to Tag must be the same type with type of Tag.Change your Web Interface AccountThe default User name is “admin” and the default Password is “a dmin”. After logging in to Web interface you can change your user name and password then click “Update Account”to update your account.。
