Carel 1tool 2646 2657 Sp1 <2025>

Carel 1tool is the primary development software for the CAREL pCO sistema programmable controller platform, used extensively in HVAC/R applications. The versions mentioned—2.6.46 and 2.6.57 SP1—represent specific historical iterations of this toolset widely used for designing, simulating, and commissioning control strategies. Core Software Environments

The 1tool suite integrates five distinct environments into a single software product to streamline the development lifecycle:

Strategy Editor: A graphical and text-based tool for developing the main control algorithms.

Mask Editor: A "What You See Is What You Get" (WYSIWYG) tool for designing the user interface (masks) on controller displays.

Network Editor: Used to graphically define the pLAN network structure, linking controllers, terminals, and electronic expansion valve (EEV) drivers.

Simulator: Provides a virtual environment to test algorithms and masks in real-time, featuring step-by-step execution and break-points for debugging.

pCO Manager: A configuration tool for commissioning, allowing users to set parameters and perform local or remote diagnostics via serial, modem, or GSM connections. Version Highlights (2.6.46 & 2.6.57 SP1)

These versions are typically distributed together in software packages for legacy system support:

Version 2.6.46: A stable release often used for standard HVAC/R project development.

Version 2.6.57 SP1: A Service Pack release designed to improve stability, add library updates, and ensure compatibility with newer operating systems like Windows Vista/7 at the time of its release. Technical Capabilities

Programming Languages: Supports standard IEC 61131-3 languages, specifically Structured Text (ST) and Ladder Logic.

Library Resources: Includes a vast library of "atoms" (80 basic elements), "macroblocks" (121 complex algorithms), and "modules" (45 functional blocks combining logic and UI).

BMS Integration: Simplifies interfacing with Building Management Systems using protocols like Modbus, LonWorks, and BACnet.

Migration: Includes a Migration Wizard to convert older projects from the legacy EasyTools platform. Application Areas

The software is used to create custom logic for a variety of units:

Air Handling Units (AHU): Management of cooling, heating, and heat recovery.

Chillers & Heat Pumps: High-efficiency control for residential and industrial units.

Telecom Centers: Specialized cooling for server rooms and mobile base stations.

The numbers "2646" and "2657" correspond to technical builds (often represented as versions like v2.6.46 and v2.6.57) found in historical software distributions and update packages for the 1tool environment. Overview of Carel 1tool

Carel 1tool is an integrated development environment (IDE) that allows engineers to manage the entire lifecycle of a software application for programmable controllers. It is divided into five core environments:

Strategy Editor: Where the main control logic is designed using functional blocks (atoms, macroblocks, and modules).

User Interface (UI) Editor: Used to design the screens and menus for the terminal displays.

Variable Editor: Central database for managing all project variables, units of measurement, and categories.

Communication Template: For defining network communication protocols (e.g., Modbus, Carel, BACnet).

Commissioning/Debugging Tool: For real-time testing, simulation, and field deployment of the code. Version Highlights (v2.6.x - v2.7.x)

Specific service packs like SP1 and builds near the 2646/2657 range introduced several critical updates to the legacy platform:

Operating System Support: Improved compatibility with newer Windows versions (transitioning from XP/7 to Windows 8).

Customization: Enhanced ability to define custom units of measurement and custom categories for variables.

Optimization: Introduced help pages for custom blocks and improved library grouping to reduce project backup file sizes.

Bug Fixes: Resolved common issues in the simulation and interface editing environments. Practical Application

If you are working with these specific versions, you are likely maintaining or commissioning older pCO3, pCO5, or pCO mini controllers. For modern projects, Carel has largely transitioned to newer platforms like c.suite (introduced in 2014) and STone (introduced in 2024), which use Structured Text (ST) for more advanced programming.
