Carel 1tool Software

Connects directly to a physical controller via USB or serial adapters to read live variable values, force outputs, and trace errors during commissioning. Key Benefits for HVAC/R Developers

When connected to a physical controller via an unLOADER or USB-to-serial converter, developers can view live variable values directly on the FBD canvas.

: Specifically manages the masks and graphical elements of the controller terminals, supporting multi-language GUIs. Connectivity and Network Configuration

Restrict critical setpoints by defining user, technician, and manufacturer password levels. 4. Network and Connectivity Configuration

: Manages the communication protocols and connectivity between controllers and Building Management Systems (BMS). A Modular Approach to Development carel 1tool software

The built-in oscilloscope function lets users log up to 16 variables simultaneously. This is critical for diagnosing intermittent faults (e.g., a suction pressure that drops only at 3 AM). Logs can be exported to .CSV for analysis in Excel.

The 1tool suite is typically divided into several integrated editors: Application Editor : Where the primary control logic and flow are built. Mask Editor

The greatest advantage of 1tool is its extensive library of certified functional blocks. Instead of coding complex thermodynamic algorithms from scratch, developers drag and drop pre-tested modules for:

Windows 10 or Windows 11 (64-bit recommended). Connects directly to a physical controller via USB

Engineers select visual blocks representing inputs, outputs, mathematical operations, and advanced algorithms.

Use standard industry symbols for fans, pumps, compressors, and valves.

The Strategy Editor is where the core control logic is built.

Carel is a well-known company in the HVAC/R industry, and their 1-Touch software is a popular tool among technicians and service providers. Here's a helpful review: A Modular Approach to Development The built-in oscilloscope

The UI module allows you to create multi-language user menus.

The different environments in 1tool share information seamlessly. This means that a change made during the design phase is instantly recognized during testing, reducing errors and saving development time.

A standard project file organizes information across several operational layers: Layer Name Primary Actions Hardware Definition

The core strength of 1tool lies in its integrated architecture, which replaces older, fragmented utilities like EasyTools. It comprises five distinct sub-environments that allow developers to manage the entire lifecycle of an application—from initial logic design to field commissioning—within a single software package. These environments include:
