Input/output X and Y are windows for executing communication with the PLC and external device or controller.

 This issued commands or data from an external device such as a push-button, changeover switch, limit switch or digital

switch to the PLC.

 Assuming that there is a hypothetical relay Xn built-in the PLC per input point, the program uses the "A" contact and "B"

contact of that Xn.

 There is no limit to the number of "A" contacts and "B" contacts of the input Xn that can be used in the program.
