  2. Can any one help me

    Hello, I am a late beginner with plc, sorry for that. I have a siemens s7 1200, 1212c Ac/DC/Relay type.I started a simple program and wired the plc using a breadboard,: input, mini bush button and output led light.The wiring seems good, because i see input led light branding when l push the push button but it does not initiate the output. But within the program by forcing the input it works. what went wrong? Thanks in advance
