Software: Carel 1tool
| | Primary Use Case | | :--- | :--- | | OEM Programmers | Writing complex application logic for chiller or rooftop unit controllers. | | Field Service Technicians | On-site diagnostics, parameter adjustments, and firmware updates. | | Facility Managers | Monitoring system performance and troubleshooting alarms via remote access. | | System Integrators | Commissioning multi-drop networks and verifying BACnet/Modbus mappings. |
Design the navigation menus and alarm displays for the user interface.
The core programming environment relies on a flow-chart layout. This visual setup simplifies the creation of intricate thermodynamic control algorithms.
1Tool includes an automatic network scanner that discovers all Carel devices on a serial line or IP network. It auto-detects baud rates and communication protocols (Modbus RTU/TCP, BACnet MS/TP/IP, Carel’s native Supervisor protocol), eliminating guesswork during system integration. carel 1tool software
A: STone is a completely new environment based on Structured Text (ST) programming. It is not a direct replacement or an upgrade for 1Tool. Projects created in 1Tool will need to be maintained with 1Tool or potentially re-engineered for STone.
A controller is only as useful as its human-machine interface (HMI). The 1Tool Touch Editor is a specialized environment for designing the graphical user interface for touch-screen terminals, such as the popular pGD Touch series. This environment allows developers to create intuitive screens, buttons, and data displays, allowing operators to monitor and interact with the system easily.
Once the application is finalized, it is uploaded to the physical CAREL controller, and 1tool provides tools to calibrate the system on-site. Applications of 1tool in HVAC/R | | Primary Use Case | | :---
Organize screens into "User Loop" (status viewing), "Installer Loop" (setpoint configuration), and "Manufacturer Loop" (advanced PID tuning protected by passwords).
Built-in blocks compute property values for various refrigerants, dew points, and enthalpy calculations.
Allows you to configure complex master-slave setups or pLAN networks connecting multiple controllers together. | | System Integrators | Commissioning multi-drop networks
In the highly specialized world of Heating, Ventilation, Air Conditioning, and Refrigeration (HVAC/R), control efficiency is everything. CAREL 1tool stands as the flagship software suite designed to program, simulate, and commission CAREL’s programmable controllers, including the widely used pCO system series.
In the Logic editor, you construct your control sequences using standard visual programming.
Supported via specific hardware gateways configured through the software. Step-by-Step Workflow: Developing a Project in 1tool
