Outline
This counter starts counting when the condition turns ON from OFF and generates an output when counting
up to the set value.
A counter initial value can be set.

Function and operation explanation
The counter starts counting when detecting the rising edge (from OFF to ON) of the input argument Coil. It
does not start counting if the Coil remains ON.
The counter starts counting from the value of input argument ValueIn. When the input argument Preset value
is reached, the output argument Status turns ON.
The current count value is stored in the output argument ValueOut.
