Step (AF)
An AF represents an interface block with any implementation of the
processing blocks in the PLC. When they are activated their parameters are
written to the interface block (see Technical Data). The behavior of the block
is defined by the PLC planner with the aid of his CFC/SFC tools.
The automation functions are provided with indices which uniquely identify
them within the recipe. These indices are necessary due to the fact that an AF
type and thus its designation can occur several times in the recipe. The
indices are numbers which start at ’1’ and which are unique within the entire
recipe. An AF will retain its index until it is deleted (but this does not result
in the indices being renumbered). The numbers of deleted automation
functions will be reused once the recipe has been saved.
By double-clicking with the lefthand mouse button on the AF you can access
the mask for detailed planning, as described on Page 4-32 onwards. You can
however also select the AF, and then call the ’Edit’ menu and ’Object
properties’.
Once the AF has been parametrized the AF box will show the name of the
interface block – in other words, the AF type designation and the apparatus
designation of up to 3 parameters which can be specified in the detailed
planning of the AF.
