mtecconnect3dcp 2.0.0

OPC-UA client classes for m-tec machines (Mixingpump, Printhead, Dosingpump)

mtecconnect3dcp Python Library

This library provides a simple interface to connect and control m-tec machines via OPC UA and Modbus. It supports different machine types such as Mixingpump (duo-mix 3DCP (+), SMP 3DCP), Printhead (flow-matic PX), Dosingpump (flow-matic) via OPC-UA, and Pumps (P20, P50) via Modbus.

Entwicklerfreundlichkeit & IDE-Unterstützung

Diese Bibliothek verwendet ausführliche Python-Docstrings und Typannotationen. Dadurch werden in modernen IDEs wie Visual Studio Code automatische Tooltips, Autovervollständigung und Inline-Hilfen (IntelliSense) unterstützt. So erhalten Sie direkt beim Programmieren Hinweise zu Parametern, Rückgabewerten und Nutzung der Funktionen und Klassen.

Hinweis: Für das beste Erlebnis empfiehlt sich die Nutzung von VS Code oder einer anderen IDE mit Python-IntelliSense-Unterstützung.

Installation

1. Install this library:

pip install mtecconnect3dcp

Example

See /Python/example.py for a full example. Below is a minimal usage guide:

from mtecconnect3dcp import Printhead, Dosingpump, Pump, Duomix, DuomixPlus, Smp

# Connect to a Mixingpump
mp = Duomix()
mp.connect("opc.tcp://<MIXINGPUMP_IP>:4840")
mp.speed = 50  # Set speed to 50Hz (20-50Hz range)
mp.run = True  # Start the mixingpump

# Connect to a Printhead
ph = Printhead()
ph.connect("opc.tcp://<FLOW-MATIC_IP>:4840")
ph.speed = 1000  # Set speed to 1000 1/min
ph.run = True  # Start the printhead

# Connect to a Dosingpump
dp = Dosingpump()
dp.connect("opc.tcp://<FLOW-MATIC_IP>:4840")
dp.speed = 30  # Set speed to 30 ml/min
dp.run = True  # Start the dosingpump

# Connect to a Pump (P20/P50 via Modbus)
pump = Pump()
pump.connect(port="COM7")
pump.speed = 25  # Set speed to 25Hz
pump.run = True  # Start the pump
