Use Calculation Cycle Inspector

The Calculation Cycle Inspector is a powerful troubleshooting tool designed to provide visibility into the intermediate calculation values processed by the Calculation Service for specific Flowsheet Maps. It offers a dynamic, user-friendly interface to monitor and inspect ongoing calculations in real time.

This tool is primarily used for diagnosing and resolving issues within the calculation logic of Flowsheet Maps. It allows you to:

• View intermediate values that are not stored in persistent tags.

• Observe how values propagate through function blocks.

• Identify anomalies or unexpected behaviors in calculations.

Key Features

• Live View of Calculations: Displays real-time updates of intermediate values as they are computed, offering a snapshot of the internal workings of the Calculation Service.

• Troubleshooting Support: Helps users pinpoint issues such as outdated timestamps, incorrect factors, or stalled values that may affect overall system performance.

• Column Filtering: Enables users to narrow down the data to specific flowsheets, function blocks, or variables of interest, making the inspection process more efficient.

• Export Capability: Allows users to export the displayed data for further analysis or record-keeping.

Example

There’s a function block in a flowsheet that is expected to output a value of 100, but the result is unexpectedly low (e.g., 0.1). The Calculation Cycle Inspector can help trace the source of the discrepancy by showing how the value was derived and whether any upstream inputs are incorrect or outdated.
