Example:

OUT TR0
X9
LD TR0
The above sample diagram shows a typical example of connecting two parallel blocks in series. Block 3 is formed when
the element X9 is introduced into the network and the two parallel blocks become the branched blocks.
TR instruction is not necessary because the（*）point is the origin line.
If have already used TR relay to connect two blocks serially, then ANDLD instruction is not necessary.

1.7 Program Simplification Techniques

If a single element is connected in parallel to a serial block, The ORLD instruction can be omitted if the serial block is
connected on top of this single element.
