Learn the programmable logic controllers with the example programs of Omron PLC ladder logic coding with a solution.

Design the basic ladder logic program for the example logic gates circuit for the image as shown in below.

Write the ladder logic for the above-shown logic diagram.

Example Programs OMRON PLC

PLC Program Description

• A, C, and inverted B are in OR operation. D and E are into OR operation. Those two results will make AND operation with G and inverted F. Final result is stored in memory coil M0
• H and I are into OR operation and the result is AND with J. Final result is stored in memory coil M1.
• M0 and M1 are in OR operation to enable or disable output Y.

Note: This PLC example is from the Omron PLC training course.
