Timer Circuit
The preset value 0 – 9999 can be designated using a data register D0 – D99 in
the standard mode or D0 – D31 in the high-speed mode. When a data register is
used, the information in the data register becomes the preset value.
Enter the TIM, TMH, or TMS instruction with the two required addresses.
Then, enter the output (OUT) instruction.

Countdown from the preset value is initiated when the operation results
directly before the timer input is on.
The timer output turns on when the timed value reaches zero.
The timed value returns to the preset value when the timer input is off.
The same timer or counter number cannot be programmed more than once.
In this event, an error message will result.
Timer preset values can be changed without transferring the entire program
to the PLC base unit again. If the timer preset value is changed during timedown, the timer remains unchanged for one cycle. The change will be
reflected in the next cycle.
If the timer preset value is changed to zero, then the timer stops operation
and the timer output is turned on immediately.
