In the past in the industrial field, the HMI touch screen is more often used as a window for human and mechanical equipment interaction, used to connect various PLCs and sensors.
Nowadays, in the context of industrial IoT, manufacturing enterprises need to integrate OT and IT technologies more often to realize their own digitalization, intelligent transformation and upgrading, and improve efficiency. So, the HMI touch screen as a key medium for mechanical equipment to connect to the Internet of Things was given a new mission – to transfer mechanical equipment data to the cloud into the Internet of Things, to help achieve the “Internet of Things”.
At present, there are a few leading domestic products networking type HMI touch screen and Internet of things of both down to connect all kinds of PLC, sensors, up to connect to the Internet of things powerful ability.
HMI touch screen Internet of things function
IOT type HMI touch screen and IoT gateway have comprehensive and various IoT functions to make the “Internet of things” easier and safer.
Through the use of remote service management platform, you can monitor the equipment at any time and anywhere on the computer, cell phone, tablet, to achieve remote desktop, PLC transmission, and online upgrade recipes and other remote service functions, greatly saving the time and cost of travel; through the use of KEM-IoT machine IoT cloud platform (based on Ali cloud platform development), you can achieve edge computing, analysis and storage of equipment data M-IoT machine IoT cloud platform can be fully connected to the Ali ecology, to achieve ten million levels of equipment online concurrency, financial lease and other applications, safe, stable and reliable, bringing greater value-added services for manufacturing enterprises; through the IoT type HMI touch screen and IoT off support MQTT, HTTP, HJ212, OPC UA and other kinds of IoT protocols and remote database writing, which can seamlessly connect to third-party MES/ERP/SCADA and other information management systems, helping to efficiently optimize production operation plans; by using split HMI, i.e. HDMI HD box, only one HDMI cable is needed to adapt to various TVs, monitors and projectors, and HMI configuration software can also be used to easily realize the factory production line Large screen display and monitoring needs, convenient and fast.
HMI touch screen human-machine interaction function
IoT HMI touch screen can be connected with various PLCs and sensors, which is the basic function of the HMI touch screen, and now the national product IoT HMI touch screen is also strengthening this skill: HMI touch screen interface can be up to four serial ports / dual network port configuration, can meet the needs of most applications; support CANopen, Modbus, and other standard common protocols, and support network port The HMI touch screen interface can be up to four serial ports / serial port / CAN port custom development/custom development, etc., to meet the communication needs of non-standard microcontrollers, sensors, etc.
