Cyclic operation in one direction is possible without restriction (this also applies to continu-
ous cyclic operation “backward”).
In the area preceding the first or the last cam a reversal of direction is possible without restric-
tion.
Exceeding the last cam value in a positive direction requires that you maintain the traversing
direction until the first cam value behind the zero point is reached.
Exceeding the first cam value in a negative direction also requires that you maintain the same
traversing-direction until reaching the last cam value after the zero point.
In the event of reversal of direction in the area between the last and the first cam value
(in this case 350 and 20), the track identifier bits of all of your assigned tracks are set or
reset respectively. Enabled interrupts are also triggered by this.
As a remedy, a track with a cam from 20 (E) via O to 350 (A) can be assigned. With this
track identifier bit, the traversing direction in the
SIMATIC S5 must then be linked and
“held”.
