This student, from Wenzhou Vocational and Technical College, successfully completed the graduation project using our Node-Red version (IoT-Fast) of the IM300 multi-function instrument of the ABB brand. Through the requirements of the school, he started from scratch to realize the application of Internet of Things technology, realized the real-time monitoring and remote control function of intelligent electrical equipment, and used the cloud platform for equipment configuration. The following is a tutorial article summarized by the students themselves.
Tutorials|ABB's IM300 multifunction meter was acquired using IoT-Fast software
This article explains how to use the IoT-Fast cloud platform configuration software to collect data from ABB's IM300 multifunction instrument.
##1. Introduction of IM300 multi-function instrument
The IM300 multifunction instrument uses the Modbus communication protocol, 485 lines to transmit data, and the appearance is as follows.
The baud rate of the IM300 multi-function instrument used this time is 19200, 8N1. The modbus register address of the three-phase four-wire wiring is as follows, and the device number is 3.
Second, the device connection data collection
This article uses the DT5019 USB to 485 converter, which connects the computer with the IM300 multi-function instrument, and the device port is configured to be consistent with the IM300 multi-function meter. As shown in the figure below.
Then open the IoT-Fast software acquisition control system, select the Modbus acquisition engine control from the left and drag it into the middle configuration bar according to the communication protocol.
Double-click the control to enter the configuration interface, select the function code FC3 according to the protocol, and then click the small pencil to enter the communication configuration interface.
Enter the protocol type according to the parameters of the IM300, select the connected port, and select RTU-buffered for communication mode
After the communication configuration is completed, return to continue to configure the data that needs to be collected, click on the lower left corner to add, fill in the information of the collection point, check the product manual to fill in the identifier, the identifier is used for equipment and platform association, the function name is remarks, the unit number is the device ID, and the address is filled in according to the register address of the instrument according to the manual query, the length is the length of the read address, the IM300 data type is integer, and the algorithm is.
The collected data is transformed.
Pull out the timer and debug control in the common control, connect it with the modbus control, and set the timer to run periodically for 10 seconds.
After you click Deploy in the upper-right corner, you can view the automatically collected and uploaded data every 10 seconds in the debug box.
Configure the remaining collection points.
3. IoT-Fast cloud platform
Enter the cloud platform system, add a product in the product center, and select a smart meter.
View the created product, and add data points for acquisition control in Function Definition - Custom Parameters.
The configuration is as follows, and the identifier is the one mentioned above, which should be consistent with the one filled in the collection control configured earlier.
Then click on the group, create the group, select up for identifier, select report for type, and select all the points on the left to join the current group.
And then onProduct Center - Device Managementto add a device under the product.
After the creation is complete, return to the acquisition control system and pull it out from the left sideIoT-Fast cloud uplinkcontrols, double-click on the controls to select the product device and group you just created and connect with the modbus control.
Click Deploy when you're doneCloud Platform - Product Center - Device ManagementCheckOperational statusYou can see the uploaded data.
You can also view these data information on the monitoring dashboard.
4. IoT-fast-cloud configuration
Click on Cloud Configuration to enterCloud configurationHome.
Create a new project, fill in the name, click into the project, use the component to draw the configuration screen you want, draw the frame, and pull out the text control from the left.
Click Bind Data on the right.
Bind the data.
Finally, configure all the interfaces, click the upper right corner to complete the save.
5. Realize monitoring at any time through the WeChat applet
