Hello Dan, Simply, the Shift Right or Shift Left instructions shifts Right or Leftthe inputvalue (IN) by number of bits (N) and put the output in the output value (OUT). This instruction is executed when the EN bit became high. So, if EN bit is low and there are more than one change in the IN value as per your question, then the OUT value will not be affected. Please check the shift instructions in this manual: S7-200 System Manual Hope this helps. |
