Carel pCO5 series controllers are primarily programmed and managed using a suite of proprietary software tools designed for the pCO sistema
platform. Depending on whether you are developing new application logic or performing field maintenance, you will use different environments. Primary Development Software
For creating, modifying, and debugging the application software that runs on the pCO5, Carel provides the following tools:
: The core development environment for the pCO5 series. It allows for complete customization of HVAC/R unit control systems through a graphical programming interface.
: Includes five integrated environments for design, testing, debugging, and commissioning.
: Offers over 120 macroblocks and 45 modules for rapid application development.
: An advanced development suite primarily designed for the newer c.pCO family, but often used in modern pCO-based system projects. It supports IEC 61131-3 standard languages like Structured Text (ST) and Function Block Diagrams (FBD).
: Carel's newest (released in 2024) development environment focusing on Structured Text (ST) programming, offering enhanced security and efficiency for newer pCO5+ models. CAREL Industries Maintenance & Commissioning Tools
Once a program is developed, these tools are used to upload files or manage the controller in the field: Programming Tools - CAREL
The Carel pCO5 controller is a cornerstone of HVAC/R engineering, designed for high-efficiency climate control. Programming it involves a sophisticated ecosystem that balances powerful software tools with convenient field hardware updates. The Core: 1tool Development Environment
The primary "brain" behind the pCO5 is the 1tool software. It is a comprehensive suite that manages every phase of an application's life, from initial logic design to final testing and commissioning.
Modular Architecture: 1tool uses a library of "atoms" (basic elements), "macroblocks" (complex algorithms), and full functional modules. This allows developers to drag and drop pre-tested HVAC/R routines, such as compressor management or PID loops, significantly reducing development time.
Integrated Environments: The suite contains five distinct sub-environments that share data in real-time, allowing for instant error reporting and seamless transitions between logic programming and user interface design.
Software Portability: One of 1tool's greatest strengths is its portability; programs written for one pCO platform can be quickly adapted for others (like the pCO3) by simply remapping the inputs and outputs. The Evolution: STone and c.suite
While 1tool remains a standard, newer models of the pCO5+ support modern environments:
STone: Introduced in 2024, this environment uses Structured Text (ST) language and focuses on high-level efficiency, security, and IEC 6244 cybersecurity standards.
c.suite: Used primarily for the c.pCO family but sharing logic principles, it supports multiple IEC 61131-compliant languages (Ladder, FBD, SFC) and enables multi-developer teamwork. User Manual User-friendly Interface : The software features an intuitive
If your pCO5 is connected to a pGD graphic terminal, TOP lets you program dynamic softkeys. Example: "Press F1 for Manual Defrost" or "Press F2 to view Historical Alarms."
Many OEMs (Original Equipment Manufacturers) protect their intellectual property by locking the code. If you connect to a pCO5 and attempt an "Upload" (reading code from the controller to the PC), you may find the code is unreadable or encrypted. This is a standard security feature. Always ensure you have a backup of the source code (the .prj or .p5m file) saved on a PC, as reverse-engineering a locked pCO5 is virtually impossible.
