Unless you know what you want, and describe it better, there is absolutely zero reason to use the TONR instruction for a one second timebase.
In fact, with a real time clock available, there is no reason to use a timer instruction at all. Create an array of 7 DINT's, and use a GSV instruction... GSV WALLCLOCKTIME LocalDateTime MyDINTArray.
MyDINTArray[5] is seconds. Do something every time it changes.
