Configuration Manager

OPC connection

This section describes the additional configuration parameters when you plan to use the OPC connection client. More information about OPC and the PRODBX-OPC driver see Knowledge base OPC.

Select OPC in the connection type listbox when defining the database connection. Your screen will look like:

• Node name or IP address: the machine name or IP address where the OPC server is installed. If you leave this field blank, the system will assume the OPC server is installed on the same machine the connection client is running on. If you leave it blank, and the connection client will run on a different machine than the configuration manager is running on, you will have to enter some entries manually. (The configuration manager will connect to the OPC server to facilitate some of the input)
• OPC server name: the registered name of the OPC server. You can enter this manually, or select from the list providing you can connect to the OPC server machine. You must have authorization to read the registry of the machine your OPC server is installed on.
• Locale Id: the numeric identification of the language supported by your OPC server. The value will be defaulted to the locale id of the machine running the configuration manager.
• Update rate: time in milliseconds the OPC server should report changes of tags. This parameter is relevant when you use the asynchronous options of the OPC server.
• Time Bias: Value in minutes. In some cases the data may have been collected by a device operating in a time zone other than that of the client. Then it will be useful to know what the time of the device was at the time the data was collected (e.g. to determine what ‘shift’ was on duty at the time). The Time zone Bias provides the information needed to convert the time stamp on the data back to the local time of the device.
• % Deadband: The % difference the value should have before a tag is reported through the asynchronous channel.
