- In this example, hypothetically, we are going to record, load the sequence of moving this robotic arm. We have different sensors along the arm. I chose 4 for simplicity. We are going to load the position of each sensor when I press on the record push button. The sensors are connected to input 1, and data will be recorded every time the record push button is pressed. Then sequence has load instruction, will read and record them in a data file B3. The record push button is connected to input 3, bit 0. The sequence will load instruction, replaces the manual loading of data into the file. It copies the data directly from the source address to the sequencer file. The length is determined by the amount of data needing to be loaded into the file. So, I'll chose 10 different data sets to be recorded within the time selected. When using Logic Simulation Software, the sensors are connected this way: sensor 1 is connected…
