In recent years, as the "industrial production 4.0" "Industrial Internet", "2025 China's manufacturing industry," the proposed industrial sectors are moving in the direction of intelligent interconnection. Industrial control has also gone three major problems:
1. Device position distribution is more dispersed, difficult operating conditions of equipment on-site supervision.
2. The agreement between the different equipment, different interfaces, brands, it is difficult docking.
3. Simple original network structure, are often not fixed public network IP, the fault diagnosis is large equipment manufacturers specializing in sales staff no remote processing conditions.
For the above problem, zero escape public IP box provides a simple and effective and flexible solution.
The principle:
In the absence of a fixed IP case, it does not change the original network structure, in the core switch next to the hanging hardware to deploy a "zero escape public IP box":
1. establishing a communication tunnel with the local network address of the server cloud zero escape acquires exclusive fixed public IP.
2. open up the local network, network penetration.
3. The desired network address and port of the device through the public IP mapping the acquired remote access to the external network.
"Zero escape" Implementation:
1. PLC apparatus may be distributed in different locations of the unified IP address mapping different ports.
2. The different plant engineering workstation, do remote desktop mapping.
3. The master control room PLC PLC master control server for mapping.
Traditional implementation shortcomings:
Traditional VPN solutions, the need to assist the deployment of multi-party, independent deployment of remote and local needs, transmission stability VPN tunnel is no way to guarantee, leaving the VPN network can no longer available for remote management.
PLC remote control software solutions, high implementation costs, software maintenance late cumbersome, multi-platform docking, node failure increases, it is difficult to guarantee security.
Features Benefits:
1. ease of deployment, reduce risk and cost of network transformation.
2. Transmission stability, according to the real location of the user, access to the nearest server, network jitter and packet loss reducing the maximum extent.
3. A flexible control, remote control according to different scenes, selecting an optimal implementation.
4. open high port supports full-forward mode and multi-protocol.
5. The safety UE extension of the user's existing security system, using the cloud Ali cloud security system.
6. confined to a small remote control, remote control can be carried out anytime, anywhere via the Internet and mobile networks.
