Since the version 2.1.1 Advanced PBX Data Logger has an internal OPC server. It means that any OPC compatible client application can get data from Advanced PBX Data Logger without any additional software. To connect to the OPC server, you need the server ID and name (Fig. 5.2.1). Before using the OPC server on your computer, you should download and install the OPC Core Components Redistributable from www.opcfoundation.org (registration required).
Fig. 5.2.1 OPC server parameters
Advanced PBX Data Logger parses all incoming data to one or more variables, and an OPC client gets it (fig. 5.2.2). After connecting to the OPC server, you will get a list of all variables.
Fig. 5.2.2 OPC server active items
Clients activity is showed on the "Active clients" tab. The top node is client, below is a group of items and connected items. By double-clicking, you can get detailed information about each node.
Fig. 5.2.3 OPC server clients
Advanced PBX Data Logger creates new variables at "on-the-fly" mode. The Advanced PBX Data Logger starts without any variables and gets it only after first data had been received. If your client OPC will connect to the OPC server before than data had been processed, then it will get an empty list of variables, and your OPC client should poll the OPC server for updating list of variables. If your OPC client doesn't allow it, then you can pre-define all variables (fig.5.2.4). In this case, the OPC server will create these variables with empty values, immediate after starting, and your OPC client will get these names while connecting.
