neqsim-plant-data SKILL.md skillA
neqsim-plant-data from equinor/neqsim is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add equinor/neqsim/neqsim-plant-data@git:20261103.75a0473Pins git:20261103.75a0473 in mdr.lock. Pin the fingerprint instead.

Connecting NeqSim simulations to plant historian data via tagreader. USE WHEN: reading OSIsoft PI or Aspen IP.21 data, building equipment tag maps, comparing simulated vs measured values, running digital-twin loops, or extracting event windows for water-hammer screening. Covers tagreader API, tag mapping, data quality, mock data, model-vs-plant comparison and valve/pump transient snapshots.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Plant Data Integration with Tagreader
Patterns for connecting NeqSim process simulations to real plant data from
OSIsoft PI and Aspen IP.21 historians using the tagreader package.
For P&ID-driven operational studies, also load `neqsim-pid-process-operations`
to map instrument bubbles and valve symbols to logical tag names, infer active
state, and drive steady-state or dynamic NeqSim scenarios.
For water-hammer or liquid-hammer screening, also load `neqsim-water-hammer` and
extract short event windows with inlet pressure, temperature, flow rate, valve
position, pump speed/status, and observed closure/trip timing for MCP
`runWaterHammer`.
## Installation
```bash
pip install tagreader neqsim
```
## Tagreader API Reference
### Listing Available Data Sources
```python
import tagreader
# Discover what historian servers are accessible
pi_sources = tagreader.list_sources("piwebapi") # OSIsoft PI Web API
aspen_sources = tagreader.list_sources("aspenone") # Aspen IP.21 REST API
```
For custom historian deployments, supply `url`, `auth`, and optionally
`verify_ssl`:
```python
from requests_ntlm import HttpNtlmAuth
auth = HttpNtlmAuth("domain\\user", "password")

How to install
mdr add equinor/neqsim/neqsim-plant-data@sha256:031575a87b1a0d1dThe line at the top of this page pins the label git:20261103.75a0473, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
