1. Function:
Industrial PLC with Ethernet port communication, TCP / IP protocol. The general communication protocol is TCP or UDP, which can communicate directly with industrial control software. The Ethernet port of the PLC is connected to a 4G router, and the industrial router is connected to a VPN network. Realize remote receiving data and controlling PLC.
2. Application:
Smart factory-industrial automation control, heating, and heating automation control.
3. Applicable equipment:
Ethernet port Modbus protocol digital-analog acquisition RTU, Siemens S7-200 / 300 series Ethernet port PLC. Rockwell Ethernet port PLC and inverter.
4. Specific cases:
a. Industrial router USR-G806:
b. Ethernet port PLC: Siemens S7-200
c. Application example: The Ethernet port of a PLC is connected to a industrial router.
d. Data statistics software:
e. Parameter settings in G806：
f. After connecting to the VPN server successfully, we can check the IP assigned by the VPN server in the "Interfaces".
g. Change these two parameters to accept.
h. Port forwarding: Set the IP and two ports of the PLC.
5. Tips:
When G806 is used as a VPN client, the server software actively accesses the G806's VPN address and port mapped external port to achieve remote communication with the PLC.
