The best free and opensource PLC software
by MectIn the world of industrial automation, Programmable Logic Controller (PLC) controllers are key tools for managing and monitoring complex processes. However, the cost of some PLC software can be an obstacle for many companies, especially small and medium-sized ones. Fortunately, there are excellent free and open source solutions that can meet automation needs without burdening the budget.
In this article, we will explore some of the best free and open source software for PLCs, also highlighting the solutions offered by Mect, a leading Italian manufacturer of industrial automation devices.
1. Mect Suite: The Integral Solution for PLCs and HMIs.
Mect Suite is a free, free software-based development environment designed to simplify the development of HMI and PLC applications. This SDK (Software Development Kit) consists of two main tools: Qt Creator and ATCMcontrol Engineering.
- Qt Creator: allows you to create intuitive and customized HMI graphics interfaces, even without the need for in-depth programming knowledge. With drag-and-drop programming and ATCMplugins, you can easily link HMI graphics to PLC variables.
- ATCMcontrol Engineering: allows the development of PLC programs using all 5 IEC 61131-3 languages (Structured Text, Function Block Diagram, Sequential Function Chart, Ladder Diagram, Instruction List).
Key features of Mect Suite:
- Real Time
- Online Debug of both HMI and PLC environment
- Remote Control via VNC
- NTP (Network Time Protocol)
- Online data logging and debugging
- Alarm, recipe and graph/trend management
- Wi-Fi and Mobile management
- Support for Modbus RTU, Modbus TCP and CANopen
Mect Suite is ideal for those looking for a compact and versatile solution that is fully integrated with Mect HMIs and PLCs.
