4.13.4 Examples
4.13.4.1 Enable Counter
The counter is active, when the variable " EnableCounter_1" is TRUE.
Term2_EnableCounter_1:=TRUE; (*Release of the counter*)
Term2_Counting_1; (*TRUE, if counter is enabled*)
Term2_Clockwise_1; (*Count direction, TRUE, when up*)
4.13.4.2 Counter Set/ Clear
Copying the contents of "SetValue_1" into the current value is executed by a
rising edge to " SetCounter_1". Execution is indicated by
"CounterSet_1=TRUE".
If "SetCounter_1" is reset (FALSE) again, "CounterSet_1" becomes also
again FALSE.
Term2_SetValue_1:=diCounterValue ; (*Copy a number into the source var*)
(* 0 = Clear*) and
Term2_SetCounter_1:=TRUE; (*copy to the counter current value*)
Term2_CounterSet_1; (*TRUE, if set*)
4.13.4.3 Set Compare Value
Configuration settings set in "Zähler 1 Optionen" are activated by the rising
edge of the control bit "SetOptions_1". The successful take-over of the
options is confirmed with the status bit "OptionsSet_1".
e.g. Set compare function.
