Carel is a development environment used to program the pCO sistema family of controllers for HVAC/R applications . It integrates multiple editors to manage a project from design through commissioning. Core Environments The software is divided into five main functional areas:
The software is built on the and utilizes a modular "plug-in" technology. It is structured into five distinct environments that manage the entire software lifecycle:
The industry standard for device-level communication.
Run the software in a "test mode" to verify that the logic reacts correctly to simulated sensor inputs.
Instead of writing complex lines of code, users can design control logic using intuitive function blocks and flowcharts. This visual approach reduces errors and speeds up development. carel 1tool software
Designing how users scroll through status screens, setpoint menus, and alarm history.
The pCO Manager environment assists with local or remote diagnostics, maintenance, and field setup. Pros and Cons 1tool - CAREL
Create intuitive menus for the keypad display. Ensure that critical parameters, such as setpoints and active alarms, are immediately accessible to field technicians. Step 4: Local Simulation

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.

To understand the place of 1tool, it is essential to see how it fits within CAREL's broader evolution of programming tools. The company has developed a suite of tools to address the growing complexity of the market:
: Must be explicitly declared in the Variable List. 1tool supports Boolean (0/1), Integer, and Analog data types (real/float values are treated as scaled integers). It is structured into five distinct environments that
Developing an application in Carel 1tool typically follows a structured four-step engineering workflow:
The you are programming (e.g., Chiller, AHU, Heat Pump).
Control logic requires an accessible operator interface. The suite includes an integrated module for designing user menus on built-in controller screens or external pGD displays.
