XIO [Examine if Open] & XIC [Examine if Closed] Explained XIO [Examine if Open] Explained Use with processors: All SLC and MicroLogix processors Example of Instruction: Description This instruction (also called "examine off" or "normally closed") functions as an input or storage bit. If the corresponding memory bit is a "1" (on), this instruction will not allow rung continuity and outputs on its rung will be de-energized. (Note Other factors may affect rung continuity.) If the corresponding memory bit is a "0" (off), this instruction will assume its normal status and allow rung continuity and outputs on the rung will be energized. (Again, other factors can influence rung continuity.) If used as an input bit, its status should correspond to the status of real world input devices tied to the input image table by the identical addresses. Addressing Help Sample: I: 12/03 In the sample address, "I" indicates input image table; ...
