AND LOD (Load)
The AND LOD instruction is used to connect, in series, two or more circuits starting with the LOD instruction. The AND
LOD instruction is the equivalent of a “node” on a ladder diagram. The AND LOD instruction is keyed after entering those
circuits to be connected.
The AND LOD (load) instruction reads programs stored in the stack register by the LOD or LODN instruction and then
AND’s them.
