    I've discovered at least one instance where implementation of code in ladder diagram leads to a result which goes against the very essence of ladder logic, and possibly doesn't comply with the standard. Specifically, using a CTU instruction. Once the count value (CV) becomes equal to the preset value (PV), the output (Q) is set and remains HIGH. Any logic operations connected to the right of Q are executed regardless of the conditions in front of (to the left) the CTU block. Notice in this example...
