The XIC (Examine if Closed) instruction in PLC programming checks if a particular bit or input is ON (logic 1). If the bit is ON, the instruction allows logic to flow to the next element in the program. Therefore, it checks for a logic input of 0 or 1 (A) and returns a true value if the input is logic 1 (B).
