This module handles the hardware configuration of the target controller, mapping physical inputs and outputs (analog and digital), and defining expansion modules.
Before deploying code to an expensive chiller or air handling unit (AHU), it must be tested.
One of the most powerful extensions is . Using Carel’s tERA or pGD touch terminals as gateways, technicians can connect to a controller located in a remote supermarket, data center, or cold storage facility over the internet. This enables:
is the integrated development environment (IDE) used to create, debug, and upload logic (programs) to Carel controllers. It is the successor to the older "1Tool" versions and is designed to work seamlessly with modern operating systems (Windows 7, 10, and 11).
The UIE handles what the end-user or technician sees on the physical controller screen or remote terminals (like the pGD line). carel 1tool software
Optimized algorithms handle the high-inertia nature of HVAC systems, preventing compressor short-cycling and temperature overshoots.
Developers start by creating a new project, setting up inputs and outputs (I/O) mapped to the specific CAREL controller hardware.
, such as specific sensor linearization or compressor management functions. End-to-End Development
What (e.g., pCO5, c.pCO) are you targeting? What type of HVAC/R system are you programming? This module handles the hardware configuration of the
Optimize strategy by removing unused blocks, lowering history logging intervals, or reducing the number of high-resolution graphic assets.
Ensure you are not in "Simulation Mode." 1Tool has a powerful offline simulator for testing logic, but you must toggle to "Online" mode and enter the correct password (usually "admin" or the OEM’s custom password).
Efficiency dictates success in the modern Heating, Ventilation, Air Conditioning, and Refrigeration (HVAC/R) industry. Hardware performance represents only half of the operational equation. The software governing the system manages the rest.
Allows for the creation of control logic. Using Carel’s tERA or pGD touch terminals as
For state machines, operating modes, and configuration parameters. 3. Step-by-Step Development Workflow
CAREL offers specific certification courses for 1tool.
Enables simulation of the application to test behavior before physical implementation.
You cannot control hardware unless you link your logic to physical terminals.
