TOYOPUC Computerlink for Python

Python library for TOYOPUC Computerlink PLC communication over TCP or UDP.

PLC Comm Family

This library is part of the plc-comm family. See the package matrix for protocol, language, registry, and install-command mapping.

Supported PLC profiles

The maintained profile table is in PLC profiles. Choose one exact canonical PLC profile from that table.

Supported device types

The shared device and range tables are in the Computerlink Device Ranges page. Use that page for supported device families, address syntax, and profile-specific notes.

Installation

pip install plc-comm-toyopuc

Quick example

import asyncio

from toyopuc import ToyopucConnectionOptions, open_and_connect, read_typed, write_typed


async def main() -> None:
    options = ToyopucConnectionOptions(
        host="192.168.250.100",
        port=1025,
        transport="tcp",
        plc_profile="toyopuc:plus:extended",
    )

    async with await open_and_connect(options) as client:
        value = await read_typed(client, "P1-D0000", "U")
        print(f"P1-D0000 = {value}")

        await write_typed(client, "P1-D0001", "U", 1234)


asyncio.run(main())
