Our last example may at first appear very complicated but can be coded us-
ing only two logic block instructions. The diagram appears as follows:
0000 0001
0505
0002 0003
0100 0101
0004 0005
0500
0006
Block c
Block b
Block a
The first logic block instruction is used to combine the execution conditions
resulting from blocks a and b, and the second one is used to combine the
execution condition of block c with the execution condition resulting from the
inverse condition assigned 0003. The rest of the diagram can be coded with
ladder instructions. The logical flow for this and the resulting code are shown
below.
