With more pre-built libraries and improved simulation tools, developers can develop, test, and deploy applications faster.
Recent updates to the 1tool suite focus on and modern system compatibility :
: Full support for Windows 10 and Windows 11, resolving previous driver issues with USB and serial interfaces.
To leverage the new features of the updated 1tool, the target pCO controller must run matching firmware. Use the integrated tool within 1tool to flash the latest pCO OS via a USB or serial connection. 4. Migration Best Practices for Legacy Projects
Handles fieldbus configuration and hardware-specific parameters.
Complex, tested algorithms ensuring secure logic.
While CAREL introduced the in 2014 and the newer STone environment in 2024 for structured text (ST) programming, 1Tool remains a critical, reliable, and widely used tool for many projects and legacy systems. 1Tool provides a robust alternative for projects requiring traditional function block programming, while STone caters to the demand for advanced, text-based programming. Training and Support
Simplifies integration with Building Management Systems (BMS) protocols like Modbus , LonWorks , and BACnet . Resource Links 1tool - CAREL
: Updated object properties for seamless building management integration.
For those new to CAREL systems, is a comprehensive, functional programming environment used to develop applications for CAREL programmable controllers (such as the pCO sistema family). It allows developers to create custom logic using standard IEC 61131-3 languages, offering a balance between ease of use and advanced customization.
Real-time error reporting and bug fixes enhance the stability of your applications.
The update optimizes compilation processes specifically for the c.pCO controller series, fully leveraging the hardware's onboard Ethernet ports and web server capabilities.
for those looking to leverage Structured Text (ST) for even higher security and efficiency in 2024 and beyond. Best Practices for Your Next Project
