Under the same network segment, how to realize PLC networking and realize remote debugging of PLC? How to upgrade the PLC remotely? PLC remote upload and download? How to configure PLC remote? How to realize PLC remote monitoring? All Baima gateways can use EOIP two-layer networking. This article uses Baima BMG5100 industrial grade 5G/4G gigabit gateway as an example to introduce the EOIP-based PLC remote upgrade configuration method under the same network segment networking mode.
With the development of the Internet of Things technology and the popularization of information technology, more and more PLC, HMI and other automatic control product manufacturers or integrators urgently need to remotely monitor, debug and maintain field devices. From the economic aspect, remote management and control can reduce the cost of manpower travel and free up the time of engineers on the road; from the technical aspect, remote management and control realize the equipment networking function and realize the industrial Internet of Things guarantee.
1. Typical application scenarios of PLC remote upgrade under the same network segment
There are multiple on-site network ports PLC, the control room needs to realize remote control PLC and remote upgrade PLC. Some PLCs can only be accessed in the local area network, and cannot be accessed across the three-layer network. At this time, the on-site PLC and the host in the control room need to be in the same network segment. For example, the PLC ip is 192.168.1.101, and the control room computer ip is 192.168.1.100 , So that it can scan to the PLC.
Second, the realization of PLC remote upgrade
Baima Technology is a manufacturer of industrial-grade IoT communication products and solutions. The current product line mainly includes: edge computing gateways, encrypted communication gateways, industrial IoT gateways, security management gateways, smart light pole gateways, industrial-grade wireless routers, etc.
Baima Technology's full series of industrial wireless gateways and industrial-grade wireless routers can use EOIP two-layer networking, and use EOIP's two-layer tunnel transmission function to open up the network.

Fourth, the effect of PLC networking
After the PC in the central computer room is configured with 192.168.1.100 ip, it can directly communicate with two remote PLCs (which can support more), as if connected to the same switch.
Realization environment: support EOIP gateway, dedicated network card (fixed public IP), if there is no dedicated network card, EOIP channel can be configured on the basis of VPN.
5. Industrial wireless gateway configuration:
Baima BMG5100 edge computing gateway , rail-mounted installation, supports MQTT, JSON, HTTP and other northbound protocols, supports OPC, Modbus, TCP, UDP, some brand PLCs and other southbound protocols, wide access, smart matching, powerful computing, 5G /4G wireless communication is the gateway box of the Industrial Internet of Things.
Log in to the Baima BMG5100 industrial 5G/4G gateway configuration interface with a PC , enter the EOIP configuration item, and enable the EOIP function.
Tunnel ID: The settings of the center and the client are the same.
Peer address: fill in the IP of the peer WAN port.
Enable bridging: After enabling, the two layers can communicate with each other.
5. Remarks:
1. The field device can be any IP device, and the network segment can be any. It only needs to be in the same network segment with the IP of the central computer room to achieve two-layer interconnection.
2. EoIP (Ethernet over IP) tunnel is an Ethernet tunnel protocol established between the IP transport layers of two routers.
3. Multi-channel can be realized, and on-site equipment can also realize mutual access.
