Timer
A coincidence signal: The timer operates in the "coincidence" mode, i.e. the output
signals are enabled for the programmed period of time after reaching the selected
preset value B trail signal: P 2 and P 0 operate in the "coincidence" mode, i.e. the
output signals are enabled for the programmed period of time when reaching the
selected preset value. P 1 is a trail preset and not absolute to 0, but relative to P 2.
If the setting is F8=1, the following will apply:
Signal 1 is returned at P 2 – P 1
Example: P 2=1000, P 1=200, Signal 1 at 800;
If P1 is negative: P 2=1000, P 1=(-200), Signal 1 at 1200
If the setting is F8=2, the following will be applicable:
Signal 1 is returned at P 2 + und – P 1
(Example: P 2=1000, P 1=200, Signal 1 at 800 or/and 1200)
C range signal: P 1 and 2 are range signals:
Output-Signal 1 is active at timer reading < P 1 and
Output-Signal 2 is active at timer reading > P 2
D batch mode: The timer can also be programmed to act as a batch counter.
In this case, P 2= main preset value; P 1= Batch preset.
In the Batch mode of operation, only positive entries are possible for P1;
negative entries will be stored as positive values.
This mode is ideal to default a process time and the number of process sequences
(runs).
