  • Page 37 Programming LOGO! LOGO!’s connectors The term connector refers to all connections and states in LOGO!. The inputs and outputs can have the state ’0’ or ’1’. ’0’ means there is no voltage at the input; ’1’ means that there is. But that is unlikely to be new to you. We introduced the connectors hi, lo and x, in order to facili- tate program entry for you.

  • Page 55 Programming LOGO! What does ”LOGO! is in RUN?” mean? In RUN, LOGO! executes the program. First of all it reads the states of the inputs, uses the program you have speci- fied to determine the states of the outputs, and switches the relays at the outputs on or off.
