Internet of Things control has always been a hot spot in industrial informatization. With the rapid advancement of various Internet of Things applications, remote data collection and equipment monitoring through the network have become the most economical and reliable way. Network controllers are used in smart building monitoring , industrial automation, power systems, intelligent manufacturing and other industrial control fields have been widely used.
The latest industrial-grade network controller developed and produced by Chengdu Zongheng Intelligent Control provides I/O data conversion to Ethernet functions, allowing the host to remotely control relays through Ethernet and control the operation of corresponding equipment through relays.
The network controller also provides an RS485 interface, supports RS485 local control, and has good expansibility. It can flexibly connect the same series of serial port I/O networking devices through its own RS485 bus to achieve various digital quantities, The combination of analog quantities expands the collection function.
This product adopts the standard Modbus TCP/ RTU communication protocol and can communicate with all configuration software and PLC devices on the market that support the Modbus TCP/RTU communication protocol. The network controller interacts with the host through RS485 communication mode, and the communication protocol is the industry standard Modbus RTU protocol.
The ModBus protocol defines a message structure that a controller can understand and use, regardless of the network through which they communicate. It formulates the common format of the message field and content, and describes the process of a controller requesting access to other devices. , respond to requests from other devices, and detect and log error messages.
Through this protocol, the exchange and transmission of information and data can be completed between controllers, controllers and other devices via the network, allowing programmable logic controllers (PLC), RTU, SCADA of various companies and manufacturers to The system, DCS or third-party equipment compatible with the ModBus protocol can be connected to form an industrial network to build various complex monitoring systems and facilitate system maintenance and expansion. This communication protocol has been widely used as a system integration solution by various industries at home and abroad. A common industry standard protocol.
This product realizes remote control function through 4G networking, and the working mode of master and slave can be freely selected; dual watchdogs of software and hardware keep the device stable online; it has good protection measures such as power overcurrent, overvoltage, and anti-reverse connection, and is easy to install. It is easy to use and reliable, ensuring that the module is suitable for industrial field environments.
