A DXMR50-LB-2PA-2P Logic Block is inserted into the existing monitoring solution, connecting a QS18 discrete PNP sensor and a red TL70 Tower Light using only a splitter and two short, double-ended cordsets. When the sensor on Input 1 detects a package, the Logic Block copies the output value to a register, forwarding it to the PLC on Output Pin 4 while leaving the existing monitoring solution undisturbed. At the same time, the Logic Block starts a 5000 ms timer, delaying the signal on Output Pin 2. If the output signal remains high for greater than 5000 ms, then the output passes to Output Pin 2, switching the red TL70 Tower Light ON. If the sensor's output signal is low before the time limit, then the timer resets and the TL70 Tower Light remains OFF, ensuring personnel are only alerted when their attention is needed while leaving the existing monitoring solution undisturbed.
