Similarly, memory M0.2 and M0.3 are memories of switch 3 and Switch 4 respectively. Network 2 is used only to create memories of respective switches that will be further used in the main program in network 3. The PLC we selected has a work memory of 250 kB, 24 V DC power supply with 24V DC 32 digital inputs, 16 digital outputs, 4 analog inputs, and 2 analog outputs on board. In this PLC ladder logic example, we have used Siemens S7-1500 PLC and Siemens TIA portal for programming a ladder logic diagram. Among 6 inputs, 2 are push buttons and the rest switch. In this PLC ladder logic example, we have used 6 inputs, 3 outputs, and 4 memory. Write down a ladder logic diagram for the above problem statement.
