An asset register for your CMMS, built from the P&IDs.
The CMMS is supposed to know about every instrument and every piece of rotating equipment in the plant. In practice it knows about the ones that broke. You schedule planned maintenance against a register that is partially populated and never matches the drawing pack.
Three drawings included on a new account.
What you do today.
- Pull the equipment list off whatever P&ID revision the engineering team last issued
- Cross-walk against the CMMS register, flag the missing entries
- Open work orders to populate the gaps, wait on data entry
- Schedule planned maintenance against a register you only half trust
What changes with Tagsight.
- Run the controlled P&ID set and get the equipment and instrument register, with the sheet on every row
- Export the register for IBM Maximo or SAP PM, or as Excel for any other CMMS
- Compare against the CMMS export, surface the missing entries in one report
- Re-run after each revision so the register stops decaying between turnarounds
The method behind the register.
Our article “From P&ID to CMMS: Building the Maximo or SAP Asset Register” sets out what Maximo and SAP PM expect at minimum, how a drawing tag maps to a functional location, and why the instrument index is the handover document.
EMS, Engineering Maintenance Solutions also published it on September 18, 2026.
Where it fits in your week.
Maintenance manager wants to know how many instruments in the plant are missing from Maximo. Run the current drawing register through Tagsight, diff against the CMMS export, report the gap by unit. The conversation with the asset information team starts from data, not anecdote.
Quarterly PM scope is built against the equipment list. Tagsight produces the up-to-date list off the latest controlled P&IDs, so the schedule aligns with what is actually in the plant.
Storeroom holds spares against a register that drifted from the drawings. Pull the equipment list, compare against the storeroom catalog, surface the spares that no longer have an installed parent.
Common questions
Does Tagsight write to my CMMS directly.
What about non-instrumented equipment like manual valves.
