Carel PCO5 is a compact programmable controller (PLC-like device) used in HVAC/R and refrigeration control. It handles I/O, sensor inputs, PID loops, timers, and communication (Modbus, CAN, Ethernet depending on model). Programming is done with Carel’s development environment (often called PCO5 software or Carel programming suite) which provides ladder-like and function-block tools, parameter configuration, and uploading/downloading to the controller.
1tool: The primary development environment for the pCO series. It’s known for a visual "function block" approach, allowing you to drag and drop elements like logic gates or HVAC-specific modules. carel pco5 programming software top
A PCO5 is useless without a user interface. The c.STER software is used to program the graphic displays (pGD1, pGD2) that connect to the PCO5. Carel PCO5 — Programming Software: Overview & Guide 1
