Abstract
The textile industry is a typical manufacturing industry of assembly line, its control is given priority to with switch quantity, and its characteristics are more procreative machines and wide distribution area. The PROFIBUS field bus technology was presented in this textile industry informatization network architecture,in order to meet their requirements of high intelligent information systems and strong communications networking capabilities. The scheme of network architecture planning was as follows:the data acquisition of textile production process and the processing systems backbone network to PROFIBUS, to the top connected to the enterprise information via industrial Ethernet, and to the bottom integrated all the field level device control systems, the process of PROFIBUS networking should be noted that the use of repeaters, network termination resistors and independent power supply. In the process of networking a variety of communication protocols conversion method was as follows:the machines that own with PLC controller are able to be added corresponding DP extension module, corresponding DP extension modules are articulated to their controlers; for the equipments with RS232/RS485 universal serial interface, the gateway device can be used to realize the serial port and PROFIBUS communication; the devices with RJ45 Ethernet interface, can be directly through the industry switches connected to Ethernet, or through the corresponding Ethernet module connected to field bus; for machines with specialized independent control system, OPC technology was used to a-chieve system integration.
