AND LD
AND LD connects in series the logic block just
before this instruction with another logic block.
The logic block consists of all the instructions
from a LOAD or LOAD NOT instruction until
just before the next LOAD or LOAD NOT
instruction on the same rungs.
OR LD
OR LD connects in parallel the logic block just
before this instruction with another logic block.
The logic block consists of all the instructions
from a LOAD or LOAD NOT instruction until
just before the next LOAD or LOAD NOT
instruction on the same rungs.
AND LD
• Three or more logic blocks can be connected in series using this instruction to first connect two of the
logic blocks and then to connect the next and subsequent ones in order. It is also possible to continue
placing this instruction after three or more logic blocks and connect them together in series.
OR LD
• Three or more logic blocks can be connected in parallel using this instruction to first connect two of
the logic blocks and then to connect the next and subsequent ones in order. It is also possible to con-
tinue placing this instruction after three or more logic blocks and connect them together in parallel.
