Function and operation explanation
1) This is a retentive timer that counts the time when the variable is ON. It starts counting the current value
when the execution condition of the input argument Coil turns ON.
The timer starts counting from "ValueIn × 1 to 1000 ms". When it counts up to "Preset × 1 to 1000 ms",
the output argument Status turns ON.
The current measurement value is outputted into ValueOut.
2) The condition of measurement ValueOut and output argument ON/OFF status is maintained even if the
execution condition of the input argument Coil turns OFF.
When the execution condition of the input argument Coil turns ON, the timer resume counting from the
measurement it holds.
