The details you provided refer to specific version or patch identifiers for Carel 1tool, a specialized development suite used to program pCO sistema family controllers in HVAC/R automation.
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: carel 1tool 2646 2657 sp1
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.

is an integrated development environment (IDE) specifically designed for creating and managing software for the programmable controller platform. CAREL Industries The version numbers 2.6.5.7 SP1
refer to specific software releases and service packs within the 1tool ecosystem, commonly used for programming pCO system controllers. scanref.ru Core Environments of 1tool
1tool comprises five integrated environments that manage the entire software lifecycle from design to field commissioning: Strategy Editor
: The primary workspace for developing control logic using atoms, macroblocks, and functional modules. User Interface Editor
: A WYSIWYG editor for designing controller masks and terminal interfaces. Network Editor
: Manages connectivity between controllers and peripheral devices. Simulation Editor
: Allows developers to test algorithms and interfaces in detail, including step-by-step execution and real-time value display. pCO Manager
: Assists in the configuration, setup, and commissioning of HVAC/R units, available as both an integrated and stand-alone tool. Key Features of Versions 2.6.x The Carel 1tool 2646 2657 SP1 is more
While specific release notes for 2.6.4.6 and 2.6.5.7 SP1 are often detailed in internal Carel Documentation , the 2.6 series generally includes: 1tool - CAREL
The Carel 1tool 2.6.46 2.6.57 SP1 refers to a specific service pack update for CAREL's legacy development environment. This software is the standard suite for programming, debugging, and commissioning the pCO system family of programmable controllers used in HVAC/R industries. 🛠️ Key Integrated Environments
The 1tool suite is unique because it integrates five distinct modules that share a single database to streamline the development workflow:
Strategy Editor: A graphical environment for creating the control logic using functional blocks.
User Interface Editor: Tools to design the screens for pGDE/pGD1 displays.
Module Editor: For defining the hardware input/output (I/O) configurations.
Communication Editor: Manages network protocols like Modbus, BACnet, and LonWorks.
ST Editor: Allows advanced users to write custom logic in Structured Text for complex calculations. 📦 Features of the 2.6.x SP1 Update
While version 2.6 is a legacy release (superseded by c.suite and STone), the SP1 (Service Pack 1) focuses on stability for long-term maintenance:
Full pCO compatibility: Supports the entire pCO3, pCO5, and pCO compact range.
Simulation mode: Allows developers to test logic on a PC without needing a physical controller.
Live Debugging: Connect directly to a running unit to monitor variables and "force" I/O states for troubleshooting.
Compiler Optimization: Improved memory management to fit larger programs into older hardware. 💡 Pro-Tips for Users Keywords integrated naturally: Carel 1tool 2646 2657 SP1,
Default Password: Most CAREL controllers use 22 as the default password for parameter access.
IP Access: If using pCOWeb for remote monitoring, the default IP is often 192.168.1.1.
Transitioning: For new projects, CAREL recommends moving to the STone environment, which offers better security and modern versioning.
