An existing manufacturing enterprise needs to collect data from its on-site PLC and upload it to the MES system, but the network adaptability of the PLC is poor, and the multi-brand PLC also puts forward higher requirements for data acquisition equipment. In this regard, Wutong Bolian provides a solution based on network segment isolator + industrial intelligent gateway, which can quickly, stably and safely collect on-site PLC data, and realize the function of external network access to obtain intranet PLC data. At the same time, it provides a system platform that is simple to configure and operate, easy to implement and maintain.
1. For the problem of deploying multi-brand PLC on site, it can be quickly solved through the built-in protocol resolution library of the industrial intelligent gateway. It supports access to PLCs such as Siemens, Mitsubishi, Omron, Schneider, Delta, Inovance, Keyence, Beckhoff, etc., real-time data collection and docking to the cloud platform or MES system of the host computer through 5G 4G WiFi Ethernet, etc., to realize configuration monitoring, large data screen, fault alarm, data analysis and other applications.
2. In view of the problem of PLC network adaptability, the network segment isolation and NAT conversion of PLC are realized through the network segment isolator to solve the problem of IP conflict and inability to access the Internet. It realizes the mapping of LAN port IP to WAN port IP through NAT and IP mapping, so that you can access the network without changing the IP address of the device (IP duplication and conflict do not affect the upper-layer network), and realize the unified planning of IP address through the custom device IP address of the isolator.
3. In view of the problem that the PLC communication interface is occupied, it can be quickly solved through the serial port ** function of the industrial intelligent gateway. Customers can configure the gateway to realize the data of one serial port and the data from the other serial port. On the premise of ensuring the normal communication of the original serial port data, other host computer software can communicate and interact with the device through the **serial port.
In addition, Wutong Bolian provides a convenient equipment access and remote maintenance platform, quickly realizes the configuration of on-site PLC data collection, quickly realizes remote programming and debugging of remote PLC and remote program operation, and provides efficient and reliable management means for production management and control.
