represent stable iterations of the 1tool platform, which was the primary development standard before being succeeded by newer environments like 1tool 2.6.46:
If you are currently working on a specific development or migration project with these tools, please let me know:
Carel typically provides software only through their (partner login required). If you need the exact changelog or installer for 2.6.57 SP1, contact Carel support or check your local distributor’s archive.
Version 2.6.46 is a mature baseline release within the legacy 2.6 branch. It is highly valued for its stability when maintenance programming is required for older installations. Carel 1tool 2.6.46 2.6.57 SP1
: Allows for real-time error reporting and virtual testing before deploying code to physical hardware.
: Includes a plugin to convert projects from the older EasyTools format, ensuring previous work is not lost.
Reduce the number of logged variables in the simulation watch window. Upgrade to 2.6.57 SP1, as it handles memory allocations for concurrent variables much better than 2.6.46. Conclusion represent stable iterations of the 1tool platform, which
What (pCO3, pCO5, c.pCO, etc.) you are targeting.
Updated standard HVAC/R functional libraries, including enhanced control algorithms for electronic expansion valves (EEV) and inverter-driven compressors.
Resolves critical issues relating to Modbus bridging, BACnet object mapping errors, and graphical rendering inconsistencies found in older 2.6 iterations. Critical Differences: 2.6.46 vs. 2.6.57 SP1 It is highly valued for its stability when
Before opening a 2.6.46 project in 2.6.57 SP1, compress and archive the entire project directory. Once a project is saved in the newer version, backward compatibility is broken, and it cannot be reopened in 2.6.46. 2. Verify Library Dependencies
Do not rely on incremental compilation when upgrading versions. Execute a "Clean All" command within the 1tool IDE to purge legacy compilation artifacts, then execute a fresh build. Carefully review the output log for any new warnings or errors concerning deprecated functional blocks or variable overlapping. Conclusion
Allow the installer to add the virtual COM port drivers required for Carel hardware keys.
