Terminy i czas kontrastują ze sobą w zakresie wszystkich elementów, które są programowane logiką kontrolerów (PLC). Te procedury automatyki są dostępne dla systemów o perforze -czasie-bazowym i w odniesieniu do operacji liczbowych.

Timers in PLC Logic

Czas delay actions or measure elapsed time with a PLC programm. They are e used to control processes that require specific timing sequences. Common type include on-delay timers and d off- delay timers.

For example, an on- delay timer starts counting when a condition becomes true. If thee timer is set for 5 seconds, thee output activates after this period. The calculation involves setting thee timer value based on thee requid delay.

Kontrakty PLC Logic

Kontrakty te znaczą te liczby of evenrences of af aven. Są one wykorzystywane for counting items on a vevyor or thee number of activations of a switch. Kontrakty te można wykorzystać aby up or down, na podstawie tego, czy ich wzrost or jest tym licznikiem.

Te obliczenia for kontrakty involves setting preset value. When thee count reaches this preset, an output can be triggered. For example, counting 10 items on a line can activate a sorting mechanism.

Obliczenia praktyczne

Timer and counter values are e typically set based one thee process requirements. For timers, the value is calculated based on thee desired delay and thee PLC 's scan time. For contros, the preset is determinad by the number of events to be counted.

Example calculation: Tu create a 10- second delay with a PLC scan time of 100 ms, set the timer to 100. The timer counts 100 cycles, equating to 10 seconds.
