13.4 Timers in Actions
These actions are executed once when the event occurs and the corresponding
step is active. When the sequencer is run through after this, an event-dependent
action is executed again only when the event occurs again.

S1: Timers in actions linked with activation of a step
S1 TL T
<time>
X As soon as the step becomes active (enters state)
the timer starts. For the specified time, the timer bit
(status of the timer) is set to 1, when the time
elapses, it is reset to 0.
x = no.

S1 TLC T
<time>
X As soon as the step becomes active and the
condition (interlock) is satisfied, the timer starts. For
the specified time, the timer bit (status of the timer)
is set to 1, when the time elapses, it is reset to 0.
x = no.

X As soon as the step is deactivated (leaves state)
the timer starts. For the specified time, the timer bit
(status of the timer) is set to 1, when the time
elapses, it is reset to 0.
