This function block generates a clock signal with a period T' given by the value of the input Takt, expressed in seconds. The given period must be two times larger than program block cycle. The clock generated by this function block will effectively have a period which is a multiple of the program block cycle time.
|Takt||I||FLOAT||Cycle period in [s]|
The output Q will stay at a logical 1 for one program block cycle. This time is part of the complete period T' (see figure).
