The OpcBarmeter control displays the value of an OPC item graphically. It has a thermometer-like look and the range of the barmeter is configurable. It has a built in scale that can be shown on either side of the meter, both, or neither. It can be configured to be displayed vertically or horizontally. The barmeter control is inherently read-only; its counter-part, the OpcTrackBar, could be used for a graphical read-write control.
The OpcBarmeter class provides properties that specify to which OPC Server to connect, when to connect to that server, and the OPC groups to add to the server after the connection is made. The ServerIdentifier property identifies the server to which the connection will be made. Using the designer's property grid, you may browse your network for the server, or you may type in a URI type string that identifies the server. The ConnectionScheme property determines when the client connects to the server (i.e. Runtime only, Design-time only, Manually, etc.). The ItemID is the OPC item to which when the connection with the OPC Server is made. After selecting the server, you may browse for the item using the designer's property grid.
