How do you check input and output in PLC?

You can check the input and output in PLC by using the force command. Through the programming instrument the input can be forced opened or forced closed depending on what the status of the contacts are set to. This can also be done with the output contacts.

What is the basic function of PLC?

PLC or programmable logic controller is a digital computer used for automation of electromechanical processes, such as control of machinery on factory assembly line, amusement rides, or lighting fixtures.

What is definition of Programmable Logic Controller?

Programmable Logic Controller (PLC) is widely used in Industrial automation system. It has a power supply, memory, processor and input output cards. Field signal are connected to INput output devices

What limits the the number of virtual input and output instructions in a PLC ladder logic?

The only thing that limits the number of inputs and output instructions is the size/amount of the PLC memory.

How do you connect 3x12v solar panels to become 24v?

You don't. 2 12v panels together don't make 24v - doesn't work that way. If you need 24v you need to get 24v panels.
