Leo Wei 1.1 2
Hunter 7.2 3 **Open Platform Communications (OPC) **is a series of standards and specifications for industrial telecommunication. They are based on **Object Linking and Embedding (OLE) for process control**.

Hunter 7.2 5 WECON provides **OPC Data Access(OPC DA)** for communicating real-time data from data acquisition devices, which is V-Box.

Hunter 7.2 12
Hunter 8.3 13 Due to OPC is based on Microsoft's COM (COmponent Model), and OPC's remote communication relies on Microsoft's DCOM (Distribute COM), and security is based on Microsoft's Windows security settings. About how to setup the DCOM on Windows PC, please refer to the following two links:

Leo Wei 1.1 35 **Interface function:**
36
37 1. Use the sqlite database to record the users who have successfully logged in. According to the login time, they are arranged in the user name drop-down box from large to small.
38 1. Remember password: use DES secondary encryption, the secret key is CPUID and network card MAC address respectively.
39 1. Configure the server address, and the software restart is required for the configuration to take effect.

Hunter 15.1 41 == **Server setting** ==
Leo Wei 1.1 42
43 The default server address is the V-NET monitoring address. When deploying a private cloud, connect to the corresponding network address. After configuring the server address, the OPC Tool restart is required to take effect.
