4.3.2 Selecting the parts type
A high-order controller can change automatically between
four different parts types.
The change of types takes place in the stop status. The sig-
nals at the inputs are then set according to the binary coding
of the desired parts type (see following table). The signals
must be applied continuously before the Checkbox PLC can
start again.
