procaaso-eip 0.1.11

EtherNet/IP (EIP) communication driver for industrial automation controllers

procaaso-eip

A Python library for EtherNet/IP (EIP) communication with industrial automation controllers.

Overview

procaaso-eip provides a comprehensive communication driver for EtherNet/IP protocol, enabling Python applications to interface with industrial controllers including VFDs (Variable Frequency Drives), motor controllers, and I/O modules.

Features

• EtherNet/IP Protocol: Full CIP (Common Industrial Protocol) implementation
• Multiple Controller Support: Pre-built drivers for various industrial hardware
• EDS File Parser: Parse and utilize Electronic Data Sheet files
• Type-Safe: Built with Pydantic for robust data validation

Supported Hardware

This library includes hardware interfaces for:

• PowerFlex 750/753 Variable Frequency Drives
• Nanotec motor controllers (C5-E-1-11, C5-E-2-11)
• Moxa I/O modules (E1212, E1242)
• Kollmorgen servo drives (AKD series)
• Mettler Toledo devices (ACT350)

Installation

pip install procaaso-eip

Or with Poetry:

poetry add procaaso-eip

Quick Start

from eip.controller_libraries.powerflex_750_controller.factory import PowerFlexFactory

# Connect to a PowerFlex VFD
controller = PowerFlexFactory.create_controller(
    address="192.168.1.10",
    port=44818,
    model="753"
)

# Control the drive
controller.set_speed_units("RPM")
controller.set_motor_np_rpm(1750)
controller.set_run(True)

Command-Line Tools

The package includes an EDS file parser:

eds-parser --help

Controllers

This library has a number of hardware interfaces that will use ethernet/IP to communicate

Running Tests

For testing changes to this library, install the required modules, then do the following:

For general tests, navigate to the tests folder and eneter the following style, referencing your specific hardware:

python -m tests.test_motor_controller

How to touch a PowerFlex device remotely

1. Ensure that the firewall is open sudo ufw allow 2244/tcp

2. Open up the wire guard connection Make sure you can ping

3. Bring up the ssh tunnel ssh -p 2244 -N -L 3301:195.168.1.11:44818 consynsys@< IP Address of the edge device > -o ExitOnForwardFailure=yes -o ServerAliveInterval=30 -o ServerAliveCountMax=3

4. Activate your VM

5. Run the tester

   python -m eip.controller_libraries.tests.powerflex_tests.UnifiedControllerTester
