7: contact of the counter, C13 (C14)
• Range A: The relay contact C13 (C14) of the counter with setpoint
value 512 switches as soon as the actual value is 512.
• Range B: When new count pulses or the counter enable are not
present, the actual value is retained.
• Range C: If the count direction is reversed DC13 (DC14), the
contact is reset when the actual value is 511.
• Range D: the count direction is set to up counting
• Range E: The Reset coil RC13 (RC14) resets the counter to 0. No
pulses are counted.
• Range F: the Reset coil is not active, pulses are counted.
Example: counting measuring pulses and setting an
output
Measuring pulses can represent lengths, rotations, angles or
other values. These program sections are required for
applications involving the filling of sacks, bags or the cutting of
foil.
The count signals are continuously present at I1. The high-
speed counter C13 counts these pulses. The counter is
automatically set to zero if the actual value equals the
setpoint. Contact C13 is then set for one program cycle. The
output Q3 is set at the same time. This is then reset by input
I8.
J
In the examples it must be remembered that there may be
a time difference of up to one program cycle between the
setpoint/actual value comparison and the processing of the
result. This may cause deviations in values.
