====== MPINO STUDIO 2 Phase 4-2 · Counter Box Functions ======

These commands count signal transitions and provide a current value and completion state.

{{ :en-us_products:mpino_studio2:counter-behavior.svg?1000 |These commands count signal transitions and provide a current value and completion state. }}

===== Common Rules =====

Use ''C'' for a 16-bit counter and ''DC'' for a 32-bit counter. The count changes once on each OFF-to-ON transition. A bit contact for the counter address reads its done state, and a ladder RESET coil initializes the current value. C0 through C10 are mapped to board functions on MPINO-8A4R(T)-S, so the examples on this page use C11 and C12.
