Hello All,
Was hoping I could get a little help with Modicon ladder logic. This is the first time I have seen Modicon logic and currently trying to convert to Rockwell. Any assistance would be greatly appreciated.
1. In the logic below does the vertical short passing through the horizontal short (highlighted) tie the two rungs together? In other words either contact left of the short can pass power between the two rungs?
2. With the SUB instructions placed side by side does that tie all three outputs from the SUB on column 3 to the input side of the SUB on column 4? If so, is this a way to create a limit instruction where if the data in 41001 is between 25 to 33 power is passed through?
