Special functions
8 256 IA (internal input A) no
9 512 IB (internal input B) no
10 1024 IC (internal input C) no
11 2048 ID (internal input D) no
Timer display (ru.43 / ru.44)
ru.43 / ru.44 displays the actual counter reading dependent on the adjusted clock source (LE.21 / 26). The
counter can be set to a value by writing on ru.43 / 44. If the clock source is changed during the running time,
the counter content is maintained but is interpreted according to the new clock source.
Timer reset input selection (LE.19 / LE.24)
The inputs which reset the timer can be specied according to the following table. The individual inputs are
OR-operated, i.e. if one of the specied inputs is triggered, the timer jumps back to zero. If a starting and reset
condition are active simultaneously, reset has priority.
(see table "Timer start input selection (LE.17 / LE.22)")
Timer reset condition (LE.20 / LE.25)
According to the following table one can dene the conditions to reset the timer additionally to the inputs. The
individual conditions are OR-operated.
LE.20 / LE.25: Timer reset condition
Bit Decimal value Condition
0 1 Modulation on
1 2 Modulation off
2 4 Actual value = Setpoint value
3 8 Change of parameter set
4 16 Power-On-Reset
Timer display (ru.43 / ru.44)
ru.43 / ru.44 display the actual counter reading depending on the selected clock source (LE.21 / 26). The coun-
ter can be set to a value by writing on ru.43 / 44. If the clock source is changed at run time, the counter reading
remains but is interpreted according to the new clock source.
Comparison level 0...7 (LE.00...LE.07)
LE.00...LE.07 dene the level for the switching conditions 37 / 38 ("Timer > Level").The switching condition is
set if the timer exceeds the adjusted value. A level in the range of -10.737.418,24 to 10.737.418,23 can be
adjusted.But only values of 0...655,35 are sensible for the counter.
