Async Python driver for igus dryve D1 motor controllers (Modbus/TCP, CiA 402)

gomc-rest

Python library for Mitsubishi PLCs over MC protocol (3E/4E) — bundles and auto-launches gomc-rest, with optional REST API exposure

factorysemantics-mes

An open-source, modular, agent-native Manufacturing Execution System. OPC UA in, honest OEE out, an ERPNext connector and an MCP agent surface.

simaticai

AI Software Development Kit is a Python library that allows you to create, package, and test AI inference pipelines for the AI Inference Server.

opensmi-server

Asynchronous Python framework for building Smart Machine Interface-compliant OPC UA servers.

modbus-connector

Cross-platform Modbus toolkit (PySide6): master client with register table, polling, live graphs, alarms and bus scanner; device simulator (slave) with register map and expression rules; passive RTU sniffer. EN/RU UI.

plc-comm-slmp

High-performance, strictly typed Python client for Mitsubishi SLMP (Seamless Message Protocol). Supports Binary 3E/4E frames for iQ-R, iQ-F, and Q series PLCs.

gx3-cli-mcp

Trace a GX Works3 ladder without opening GX Works3 — read-only CLI + MCP server so anyone (or an AI agent) can find why a coil never turns on.

metriplane

Open-source physical observability for robotics workcells: deterministic replay, verifiable incident evidence, and generated regression tests.

ignition-mcp

MCP server for Inductive Automation Ignition — tags, alarms, history, projects, and full Perspective deployment

watlowlib

Async-first Python driver for Watlow temperature controllers over RS-232 / EIA-485. One protocol-neutral Controller API speaks both Standard Bus (BACnet MS/TP) and Modbus RTU, with auto-detect, a typed cross-protocol parameter registry, a multi-device manager, drift-free streaming into pluggable sinks, a sync facade, and CLIs.

fanuc-python

A toolkit for controlling a FANUC robot from Python, built on the MAPPDK KAREL driver. Reads and writes the current position, joint angles, registers, and digital I/O, controls a gripper, sends motion commands, runs TP programs, reads alarm state, and ships a fanuc command-line tool you can use straight from the terminal.

kv-hostlink

Reliable Python client for KEYENCE KV series PLCs using the Host Link (Upper Link) protocol. Supports KV-8000, KV-7500, and KV-5500.
