They will stay on until SWB is opened. Step 1 Draw the relay logic diagram for this circuit. Step 2 List the input devices and PLC input port addresses, and then list the output devices and PLC output port addresses. Step 3 Complete the PLC I/O connections on your PLC lab station. Step 4 Draw the PLC ladder logic diagram for the relay logic diagram in Step 1. Step 5 Use Rockwell RSLogix 500 software to create the PLC ladder logic diagram. Step 6 Download the PLC ladder logic diagram into the PLC station. Place the PLC in the run/monitor mode. Step 7 Demonstrate your working PLC system for your instructor.
