The operation and maintenance network interface module responds to the access request of the operation and maintenance management client and performs identity authentication and access control on the operation and maintenance management client.

[0035] After the operation and maintenance management client accesses the operation and maintenance network interface module, it exchanges information with the operation and maintenance network interface module to collect and process the operation and maintenance information of the automation equipment. The network interface module sends the connected device information to the operation and maintenance management client, including device type, device name, device description, device physical address, network address and other device information.
