Demo Prompt

The following prompt was submitted to FrameworX AI Designer along with the two attached documents. The AI read both files and built the entire solution autonomously based on this input.

<role>
You are an automation engineer in life and science business and specialized in FrameworX.
</role>

<context>
I have attached 2 files, one is the specification which describes how the project is actually planned in .pdf, it mentions the UNS structure (tags), device information and alarms, and the other one is an excel which defines the address for the device. And my final goal here is to create a FrameworX solution to implement an automation project
</context>

<instruction>
1 - Read both files and understand the implementation
2 - Make the plan to implement the UNS, alarms, historian, 3x2 dashboard displays with 3 gauges, 2 trends, 1 alarmviewer.
3 - Wait for my approval to start creating the solution 
4 - When building this FrameworX solutions module by module, always stop and wait for explicit confirmation before starting the next module, no exceptions.
</instruction>

Devices and OPC-UA Connection

Field data flows in over OPC-UA from the DeltaV controller. The connection uses one channel feeding one node and 21 read-only points; the two computed Calculation tags do not map to a device address and are populated by server-side scripts.

Certificate Setup Required

On first Runtime start, the OPC-UA connection requires manual certificate trust exchange between FrameworX and the DeltaV server. Use the OPC-UA Certificate Manager in FrameworX to trust the server certificate, and ensure the fxopc_svc account is configured on the DeltaV side with appropriate read permissions on all ns=2 nodes.

Critical Alarm Limits

cGMP Design Note

The Critical alarm group requires operator comments on acknowledgment (AckRequired: Comment). This ensures every critical alarm acknowledgment generates an audit trail entry — a requirement under FDA 21 CFR Part 11 and EU Annex 11 for electronic records in pharmaceutical manufacturing.

Historian Configuration

The demo records 20 analog process values continuously, organized into two historian tables and kept on disk for 365 days using the built-in tag historian. Deadbands are set in engineering units so logged values reflect process-significant change rather than sensor noise.

Quality Flag Logging

Both historian tables have SaveQuality: true — OPC-UA quality flags (Good/Bad/Uncertain) are stored alongside every value. Bad-quality readings must be excluded from batch records and process capability calculations.

Displays

The demo opens to a single process overview screen that shows all six suites at a glance. Suite panels are color-coded, each suite has tank visuals and vertical bargraphs for every process variable, and a full-width 30-minute trend strip runs across the bottom.

Process Notes for SCADA Configuration

  1. OPC-UA Security: All process tags use SignAndEncrypt / Basic256Sha256. Certificate exchange must be completed on first runtime start. The service account fxopc_svc must have read permissions on all ns=2 nodes in DeltaV.
  2. cGMP Audit Trail: Critical alarms require operator comments on acknowledgment. All alarm events (active, acked, normalized) are logged to historian for regulatory compliance.
  3. Calculation UDT Tags: The DOStats and PressureStats tags have no device points. They will be populated by server-side Script Tasks computing rolling statistics to feed ML.NET pipelines.
  4. Historian Quality Flags: SaveQuality is enabled on both historian tables. OPC-UA Bad quality samples must be excluded from batch record analysis and process capability calculations.
  5. ML Opportunity: Bioreactor DO and temperature, UV absorbance chromatography peaks, centrifuge pressure patterns, and WFI conductivity drift are the primary candidates for ML.NET anomaly detection and forecasting models.
