Technical Field

[0002] Four / Eight-way Solenoid Valve Controller It can control four or eight solenoid valves. This controller is commonly used in industrial automation systems, communicating with other devices through the ModBus protocol to achieve precise control of the solenoid valve. ModBus is an open protocol that allows devices from different manufacturers to communicate without paying royalties, so it is widely used in the connection and communication of industrial electronic equipment. The ModBus protocol supports a variety of electrical interfaces, such as RS-232, RS-485, etc., and can be transmitted on various media, such as twisted pair, optical fiber, wireless, etc. This enables the ModBus four / eight-way solenoid valve controller to be flexibly applied in different industrial environments. In addition, the ModBus protocol adopts master-slave communication technology, that is, the master device actively queries and operates the slave device. Typical master devices include industrial computers and industrial controllers, etc., while the slave device can be a programmable logic controller, etc. In the ModBus system, data is sent in the form of a series of 1s and 0s, called bits. Each bit is sent as a voltage, where 0 is sent as a positive voltage and 1 is sent as a negative voltage. Data is stored in four different tables in the slave device, including discrete values ​​and numerical values. Each coil or register has a read-only table and a read-write table for storing and controlling the state of the solenoid valve. Each slave in the network is assigned a unique unit address. When the master requests data, the slave device to be accessed and the operation to be performed are specified by sending the slave address and function code. The function code tells the slave which table to access and whether to read from or write to the table, thereby achieving precise control of the solenoid valve. With the development of society, controllers are used when solenoid valves need to be controlled.
