: Provides a highly realistic simulation of hardware (such as voltmeters and switches) to test algorithms and interfaces without physical hardware.

The 1tool suite is built on that work together to manage a software application's entire lifecycle:

While specific changelogs for internal versions are often restricted to CAREL training participants, these versions represent stable iterations of the legacy 1tool platform before the full transition to newer tools like or STone . carel 1tool 2646 2657 sp1

: All environments share a single database of variables, ensuring that changes made in the strategy editor automatically reflect in the mask editor or documentation.

: Manages the communication between controllers and BMS (Building Management Systems) protocols like Modbus, LonWorks, and BACnet. : Provides a highly realistic simulation of hardware

is an integrated software suite used by OEMs and HVAC/R technicians to develop, configure, and commission applications on CAREL programmable controller platforms. The specific version string "2.6.46 2.6.57 SP1" typically refers to a comprehensive software package or update path found in technical repositories like Google Drive , designed to provide the necessary tools for managing pCO series controllers.
