Dialog Box
The high-performance Valve Dynamo dialog box contains the following properties:
- Valve Data Source - Allows you to enter the data source that animates the Valve Dynamo. Click the browse button (...) to browse data sources in Expression Builder. Click the down button to view the last data sources you used. These Dynamos are designed to support iFIX real time data, OPC, and Proficy Historian. Proficy Historian data source is supported for the current value.
-
Valve Values - Allows you to enter the following:
NOTE: Currently, this dynamo does not support complex mathematical expressions, Picture object properties, or Global Variables.
- Valve Closed and Open values - Specify the values for the valve to close or open, and allows you to accept corresponding default colors or select new colors from the high performance Color Box. The following illustration shows the default colors.
- Tolerance - Specifies the rounding factor to be used for the Valve Closed and Valve Open values. Typically, iFIX uses this value when comparing a process value to a target value. If the process value is within the specified tolerance, iFIX assumes the two values are equal. For example, if the target value is 1.0, the tolerance is 0.1, and the current value of a data source is 0.8, iFIX does not assume the two values are equal because the data source is not within the specified tolerance. The value must be within the range 0.9 to 1.1 to equal the target value.
