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.
When using WindLDR, the user needs not program the AND LOD instruction. The circuit in the ladder diagram shown below is
converted into AND LOD when the ladder diagram is compiled.
OR LOD (Load)
The OR LOD instruction is used to connect, in parallel, two or more circuits starting with the LOD instruction. The OR LOD
instruction is the equivalent of a “node” on a ladder diagram.
When using WindLDR, the user needs not program the OR LOD instruction. The circuit in the ladder diagram shown below is
converted into OR LOD when the ladder diagram is compiled.
