Carel 1tool Software -

The software is available for free download from Carel’s official website. It connects to controllers via USB, Ethernet, or serial interface (using Carel’s programming keys or gateways). While the software is free, some advanced features or protocol libraries may require a license key.

In short: Carel 1Tool software transforms complex controller configuration into a streamlined, visual, and efficient process — essential for anyone working with modern HVAC/R automation.

Carel 1tool is an integrated software suite used to develop and manage application software for CAREL programmable controllers (pCO sistema). It is a legacy tool that remains highly relevant for HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration) applications due to its five integrated environments covering the entire project lifecycle. Key Components of the 1tool Suite

The software is divided into five distinct environments that share data to streamline development:

Strategy Editor: Used for creating the control logic using Function Block Diagram (FBD) language. It includes a library of atoms, macroblocks, and modules that can be imported to save time.

Mask Editor: A WYSIWYG (What You See Is What You Get) interface for designing the user interface (UI) screens that will appear on the controller's display (like the PGD1).

Simulation Editor: Allows developers to test their application code step-by-step on a PC before ever uploading it to hardware. It can simulate both the logic and the user interface.

Network Editor: Manages connectivity between different devices, allowing you to configure protocols like Modbus, LonWorks, and BACnet to interface with Building Management Systems (BMS).

pCO Manager: The environment dedicated to commissioning. It allows you to configure unit parameters and perform local or remote diagnostics via modem. Core Libraries

The power of 1tool lies in its modularity. The official 1tool documentation highlights three main levels of pre-built logic: 80 Atoms: The most basic logical elements.

121 Macroblocks: Pre-set algorithms based on secure, consolidated logic.

45 Modules: Complete function blocks that combine a control algorithm with its associated UI mask. Getting Started & Resources

If you are new to the software, keep these best practices and resources in mind:

Learning: CAREL typically requires users to attend a specific training course before purchasing the software to ensure autonomy in design and installation.

Development Rules: Follow standard guidelines like using a "Template_Project" to start new applications and ensuring every variable has a description for automated documentation.

Video Tutorials: There are comprehensive video tutorials on YouTube that cover basic exercises like creating a simple thermostat.
