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"
also becomes FALSE again.
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*)
Set Compare Value
Configuration settings set in "Counter 1 Options" 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".
For example, set compare function.
