Basic Ladder Diagrams Section 4-3
Again, with the method on the right, a maximum of eight blocks can be com-
bined. There is no limit to the number of blocks that can be combined with the
first method.
The following diagram requires OR LOAD instructions to be converted to
mnemonic code because three pairs of conditions in series lie in parallel to
each other.
The first of each pair of conditions is converted to LOAD with the assigned bit
operand and then ANDed with the other condition. The first two blocks can be
coded first, followed by OR LOAD, the last block, and another OR LOAD, or
the three blocks can be coded first followed by two OR LOADs. The mne-
monic code for both methods is shown below.
Again, with the method on the right, a maximum of eight blocks can be com-
bined. There is no limit to the number of blocks that can be combined with the
first method.
