Outline Performs an OR operation on multiple instruction blocks.
Program example
■ Explanation of example ■ Time chart
• Y0 goes ON when both X0 and X1 or both X2 and
X3 turn ON.
Description
• The ORS instruction is used to connect blocks in parallel.
• A block begins with the ST instruction.
• When two or more instruction blocks are programmed in parallel, make a program as follows.
