Create powerful and flexible custom calculations using OPC Expert’s calculation engine without programming or complicated script. Calculations within controllers (RTU, PLC or DCS) use precious CPU cycles and are difficult to troubleshoot. OPC Expert makes it simple to create calculations with an easy-to-use drag-and-drop interface. Write calculations as they would appear on paper and test each calculation individually before deployment. Calculations can include a single item (measurement) or even multiple items for remarkable results.

Create new items by performing calculations on existing items. Any calculation on an item (either physical or virtual) results in a new calculated (synonymous with virtual) item.
Enter formulas as they appear on paper and avoid complicated scripting or programming requiring special training. Just enter each formula exactly as writing it by hand (for example: Flow1 + Flow2)
Adjust individual measurements by adding an offset and multiplying by a factor. This enables compensation for instrument drift or simply adjusting for proper engineering units. Example: (Flow1 – 4) * 16
Calculate on a schedule or on data change events by selecting as such in the item options. These options enable OPC Expert to optimize operation to generate results only when values change or on a preset schedule thus reducing computer load.
Modify data types by casting calculation results as integers, decimals or even text. OPC Expert explains each data type with examples and ranges.
Test each calculation before deployment with the press of a button. OPC Expert immediately validates the calculation and shows the result if appropriate. Detailed error descriptions help users modify calculations appropriately without having to exit the calculation window.
Take action on new calculations by:

OPC Expert does not require installation, does not change Windows Registry and is free to download, making it safe to use on any computer. Download OPC Expert and find out how easy it can be to create custom calculations without having to program or use complicated scripts.
