O.S.S.D.A.S v1 stands for Open Source Solar Data Acquisition System. I have been working on this project since last few months. The picture below is the not the first prototype, but the first working prototype that looks like quite complete. There will be further revisions to the hardware and software for best efficiency and accurate results. Moreover, the recorded digital data should be rich enough to reflect the real world data’s mirror. [ ]

XIO Examine if Open XIC Examine if Closed Explained

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; ...
