Counters - HEIDENHAIN TNC 415 Technical Manual

2.4.2 Counters

32 counters are available in the PLC. Each of these 32 counters is controlled by special markers with
the abbreviation symbol C. After setting a marker from the range C0 to C31 the counter is loaded
with the value from machine parameter MP4120.X. The marker range C48 to C79 indicates whether
the count has been completed or not. The marker range C96 to C127 is used to start the counter
(counter release pulse).
