There are two ways to achieve timers that operate for longer than 999.9 se-
conds. One method is to program consecutive timers, with the Completion Flag
of each timer used to activate the next timer. A simple example with two
900.0-second (15-minute) timers combined to functionally form a 30-minute tim-
er.

In this example, 00200 will be turned ON 30 minutes after 00000 goes ON.
TIM can also be combined with CNT or CNT can be used to count SR area clock
pulse bits to produce longer timers. An example is provided in 5-14-4 COUNTER

TIM can be combined with KEEP(11) to delay turning a bit ON and OFF in refer-
ence to a desired execution condition. KEEP(11) is described in 5-9-4 KEEP –

ence to a desired execution condition. KEEP(11) is described in 5-9-4 KEEP –
KEEP(11).
To create delays, the Completion Flags for two TIM are used to determine the
execution conditions for setting and reset the bit designated for KEEP(11). The
bit whose manipulation is to be delayed is used in KEEP(11). Turning ON and
OFF the bit designated for KEEP(11) is thus delayed by the SV for the two TIM.
The two SV could naturally be the same if desired.

In the following example, 00500 would be turned ON 5.0 seconds after 00000
goes ON and then turned OFF 3.0 seconds after 00000 goes OFF. It is neces-
sary to use both 00500 and 00000 to determine the execution condition for TIM
