Thirteen skill areas, each running locally with its own posture toward your systems — from reading a live OPC UA tag to drafting a fleet-wide PLC obsolescence plan. No hidden capabilities: what's below is what it can do.
Every skill runs on the engineer's machine, not in our cloud. Read-only skills act without asking; anything that changes something on a real system always stops for your approval first.
Read and write Modbus registers/coils and OPC UA tags directly against live equipment. Reads run automatically; writes are always scoped to the device and wait for your yes.
Parse a Rockwell Studio 5000 / RSLogix L5X export: tags, comments, ladder-logic rungs, and Structured Text — filter to one program, routine, or tag.
Follow a tag across rungs, routines, and multiple controllers exported from the same line — the cross-PLC view for produced/consumed tag issues.
Git-style +/- diff between two L5X exports — tags and rungs — so you can review a backup vs. a working copy, or before/after a migration, like a code change. Rungs match by content, not position, so a rung that only moved shows as unchanged.
Grounded in platform instruction-set notes, propose translated rungs for a version bump or vendor change, shown as the same git-style diff — written to a review patch file, never a live controller.
Pull a controller's full I/O and communication-module inventory from its program export — catalog numbers, revisions, rack/adapter topology — to see what hardware a migration actually touches beyond the CPU.
Every program Rung parses — during ordinary troubleshooting, not a special audit — quietly builds a shared, site-wide inventory of vendor, model, and firmware on the on-site relay. Ask what's on this site and how old it is, any time, without walking the plant. Opt-in via /memory auto.
Grounded in the site's PLC fleet, the I/O footprint, and a curated vendor lifecycle/replacement reference, draft a structured migration + validation plan — replacement hardware, code/I/O/comms impacts, phased steps, test plan — as a review document, never a live change.
Ping, traceroute, DNS lookups, and TCP port checks to map segmentation, find comms drops, and validate paths across OT networks.
Parse ArchestrA SMC exports, Windows event logs, and generic text logs by severity, with regex filtering — built for logs too large to read by hand.
Read, search, and edit local files and exports with diff previews; run shell commands for diagnostics. Anything beyond a safe read waits for your approval.
Run read-only SELECT queries against an Aveva Historian Runtime database — tag history, live values, storage nodes.
Searches Rung's curated OT knowledge base — vendor notes, runbooks, and structured troubleshooting playbooks it can walk you through.
