Hardware Description

Module
To distinguish between the IP 266 modules in a PLC, you can assign each IP a
number between 1 and 99.
Axis type
This machine data item is used to specify either a rotary or a linear axis. A linear
axis has a restricted traversing range, which must be limited via hardware limit
switches.
There is no limit to the traversing range of a rotary axis.
Start. point=End point
On each revolution, the axis goes from the starting point
to the end point. The values assigned for these points
specify the traversing range of the axis. Both points are at
the same physical position. One complete revolution of
the axis does nothing more than change the actual value
indication from the start value to the end value of the
traversing range.
