Always create a full backup before opening a 2.6.46 project in 2.6.57 SP1, as the library references may need to be updated.
A tool to manage communication protocols (Modbus, BACnet, LonWorks, CAREL pLAN) and map variables between controllers and supervisory systems (Boss, PlantWatchPro).
When 2.6.57 neared completion, it felt like the product of many small, careful improvements rather than a single big rewrite. The changelog read like a sequence of patient decisions: a hardened update flow, expanded device compatibility, tightened security around remote sessions, and a new “diagnostics suite” that bundled the automated tests. The release candidate passed an exhaustive set of lab tests and a week of pilot deployments. Carel 1tool 2.6.46 2.6.57 SP1
