Ashigo · Rung · Skills

Everything Rung can actually do on your machine.

Nine skill areas, each running locally with its own posture toward your systems — from reading a live OPC UA tag to explaining ladder logic nobody's touched in years. No hidden capabilities: what's below is what it can do.

Read-only — never prompts Changes something — always asks first
The skills, one by one

What each one actually does.

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.

Protocols

Industrial protocols

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.

Reads: safe Writes: approval
PLC programs

Read a PLC program

Parse a Rockwell Studio 5000 / RSLogix L5X export: tags, comments, ladder-logic rungs, and Structured Text — filter to one program, routine, or tag.

Read-only
PLC programs

Trace a signal

Follow a tag across rungs, routines, and multiple controllers exported from the same line — the cross-PLC view for produced/consumed tag issues.

Read-only
Network

Network diagnostics

Ping, traceroute, DNS lookups, and TCP port checks to map segmentation, find comms drops, and validate paths across OT networks.

Read-only
Files & logs

Log analysis

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-only
Files & logs

Files & shell

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.

Reads: safe Writes/commands: approval
Historian

Historian queries

Run read-only SELECT queries against an Aveva Historian Runtime database — tag history, live values, storage nodes.

Read-only · SELECT-only
Shell & knowledge

Knowledge & playbooks

Searches Rung's curated OT knowledge base — vendor notes, runbooks, and structured troubleshooting playbooks it can walk you through.

Read-only
Every skill above

Approval, every time

Every skill above runs locally. Anything beyond a safe read shows you exactly what it's about to do and waits for allow once / allow always / deny — and it's logged.
