PIM PLC Program logic controller control method using PIMPLC IP Manger

摘要

A PLC control method using a PIM (PLC IP Manger) connected to a local network connected to at least one programmable logic array (PLC) via a hub is disclosed. A PLC control method using a PIM (PLC IP Manger) comprises the steps of: individually recognizing the IP of the PLC having the IP of the PIM by the DHCP method or manually, and recording the information; Providing the TCP / IP address accessible by the PIM to a server existing in a public Internet network; Providing a host PC with a TCP / IP address accessible to the server; Receiving the TCP / IP address of the host PC from the server, and receiving the TCP / IP address of the PIM from the server; And the PIM initiating the secure communication with the host PC. In this embodiment of the present invention, the PLC is indirectly accessible to the Internet network, and the host PC (HOST PC) existing at a remote location can directly access the PLC and the host PC with PIM So that remote PLC equipment can be smoothly controlled.
