Symbol Description
=
D5Z08X1B
To obtain more space for representing a group of related
elements, contours of the elements may be joined or cascaded if
the following rules are met:
There is no functional linkage between elements whose common
contour line is oriented in the signal flow direction.
Note:
This rule does not necessarily apply to configurations with two or
more signal flow directions, such as for symbols with a control
block and an output block.
There exists at least one logical link between elements whose
common contour line runs perpendicularly to the signal flow
direction.
