Example of retrieving the 2 limits of travel of a pneumatic cylinder
In the table below you will find an excerpt from a STEP 7 user program for
retrieving the two limits of travel of a pneumatic cylinder.
Assumptions
The following assumptions apply to this STEP 7 user program:
In the example the pneumatic module is inserted directly adjacent to the basic
module. Its address is therefore 0.
The pneumatic cylinder is controlled by means of a valve on the pneumatic
module.
The inputs I 0.0 ”cylinder down” and I 0.1 ”cylinder up” are used for the
pneumatic cylinder limits of travel.
The pneumatic cylinder is controlled by means of output O 0.0.

When cylinder at limit of travel ”down”
and instruction ”cylinder up” queued
the output is set, i.e. cylinder moves upwards
When cylinder at limit of travel ”up”
and instruction ”cylinder down” queued
the output is reset, i.e. cylinder moves downwards
