1. Cycle time – In Carel μC, the actual cycle time is defined in the project settings (typically 1s for refrigeration). Adjust the compressor_delay decrement accordingly.
2. I/O mapping – You must map AI_AI1, DO_COMPRESSOR, etc., to physical PCO5 terminals via the I/O Manager in the Carel software.
3. Real-time clock – For time-based delays, use GET_TIME_SEC() instead of simple decrements in production code.
4. Compilation – This code assumes the Carel µC IDE (or c.Suite for newer controllers). PCO5 uses the legacy µC language.
5. Alarm management – Add an alarm log using ADD_ALARM() if needed.

Unlike basic controllers, pCO5’s TOP environment includes a PID_AUTOTUNE routine. You can inject a step response into the system (e.g., sudden heat load) and the software calculates optimal Kp, Ki, and Kd values automatically.

The primary programming software for the controller is 1tool . For the newer pCO5+ models, developers can also use the STone environment. Primary Development Environments carel pco5 programming software top
