I IntroductionFrom Industry 4.0 in Germany and Industrial Internet in the United States to the issue of "Made in China 2025" Program in our country, our company caters to the industry trend. In order to accelerate the development of domestic industrial informatization, we have introduced the first generation of ASC5200 intelligent gateway, which provides rich Hardware interface and supports a variety of communication protocol to solve industrial system networking problem. The realization of remote monitoring, unattended function.II Main featuresMultiple communication interface (2 channel RS485, 1 channel RS232, 1 channel USB, 1 channel GPRS);
Support Modbus RTU Master, Modbus RTU Slave, MQTT protocol;
4 channels DO, 2 channels DI, 1 channel frequency count input interface;
Easy parameter configuration, communication protocol of each communication interface is optional;
Remote access to data, issued control commands;
24VDC Power supply;III Application
Unmanned site, remote control system application
Industrial Internet of Things Systems
DCS system Internet of things transformation and application.
Other data monitoring, acquisition measurement applicationsIVTypical Application Block DiagramAs shown in Figure 1, the second 485 port of the ASC5200 remote intelligent gateway is a Modbus RTU Master, which is hung on three Modbus RTU Slave and an ASC4000 wireless concentrator for collecting wireless instrument data; An ASC5200 data collector collecting for instrument of 4~20Ma; An ASC5120 power monitoring module for collecting electrical parameters. With 485 interface and Modbus protocol, the gateway read the data of these three devices. The PLC and HMI obtain all the data from the ASC5200 via 485 and 232 interfaces, respectively. At the same time, ASC5200 also transmits real-time data alarm information to the server
through GPRS, and receives the control command from distance.
As shown in Figure 2, the application of ASC5200 in the DCS system IOT transformation in the application, without changing anything in the former system, only need to join the ASC 5200 gateway between PLC and HMI/PC. One of the gateway 485 interface connects PLC to do the communicates between Modbus and PLC, while the other gateway interacts with HMI/PC, which
acts as a branch of Modbus to exchange figures. The gateway collects the data and send it to the cloud systems without any effect of original function, so that users can monitor the original DCS systems in any network.
