What if the legacy P&IDs are scanned at low quality.

Sharp scans yield a clean result. A degraded scan just means more rows to confirm by hand in the canvas before export.

Can Tagsight feed the DCS modernization tag table.

Yes. Once the I/O baseline is reconciled, exports to TIA Portal, Rockwell L5X, or PLCCreator hand the modernization team a clean tag table. Reconciliation surfaces tags-in-DCS-not-on-drawing and tags-on-drawing-not-in-DCS deltas before the new platform inherits them.

How are recovery boiler SIS tags surfaced.

Black-liquor firing protection, low solids, low gun pressure, drum level is drawn with explicit SIS annotations on most modern standards. The extraction filters those tags into the SIS register for NFPA 85 documentation.

Does this work on hand-redlined P&IDs.

The extraction reads what's printed on the drawing today, including redlines where legible. Heavy redlines reduce confidence on the affected rows. The review step surfaces them for disposition. For mills with unposted redlines, the extraction is often the forcing function to consolidate them into a controlled drawing revision.

Can the extraction support a stock-prep modernization where loop tuning data matters.

The P&ID carries the tag and signal class. Loop tuning constants live in the BPCS configuration and the loop folder, not on the drawing. The extraction is the upstream input to a loop-tuning project, not a substitute for it.

P&ID extraction for pulp and paper.

Pulp and paper mills inherit decades of partial modernization. DCS systems installed in the 1980s, partially upgraded in the 2000s, sit alongside hand-redlined master P&IDs nobody has reconciled against the live point list.

Recovery boiler controls carry SIS scope per NFPA 85. SIS-tagged instruments separated on export
Bleach plant chemistry tags, ClO2, peroxide, NaOH preserve analyzer scope through extraction
Hand-marked redlines on the master P&ID set extract as drawn today, not as originally drafted. Low-confidence redline rows surface for review
Continuous and batch digester scope differ. Batch, Kamyr, Pandia carries phase-stepping interlocks. Continuous digesters carry steady-state level and flow control
Stock-prep and headbox instrumentation, consistency, freeness, basis weight runs at tight loop-tuning tolerances
Power and recovery islands, recovery boilers, lime kilns, turbogenerators carry combustion SIS scope. KKS conventions appear on European-supplied equipment
Effluent treatment and clarifier instrumentation feeds environmental compliance reporting. Audit-trail columns support permit responses
Legacy Allen-Bradley PLC-5 and Provox DCS environments hold tag databases that often diverge from the as-built drawing. The reconciliation report surfaces the deltas

NFPA 85 governs combustion controls on recovery boilers
OSHA PSM applies to certain pulp mill processes, chlorine, NaOH bulk handling
Provincial, state environmental regulators audit emissions instrumentation. The extracted dataset feeds those audit responses
