Fig. 13.2−49 Terminal assignment of the 2/4xcounter in the mode 27
The mode 27 offers two 32−bit counters which can be assigned with a starting
value.
The counting direction is determined via the signal level at input IN3 / IN6 (DIR):
Upcounter: LOW level
Downcounter: HIGH level
If a HIGH level is applied to input IN3 / IN6 (G/RES), the counter is incremented or
decremented by 1 with each LOW/HIGH edge.
During the counting process a HIGH level must be applied to input IN1 / IN4
(G/RES). With a LOW level the counter content is frozen. With a rising edge at the
input IN1 / IN4 (G/RES) the counter is deleted.
When the counter reaches zero, the output OUT0 / OUT1 is set to HIGH level for
at least 100 ms, even if the counter continues to count. When the counter stops
at zero, the output OUT0 / OUT1 remains on the HIGH level.
