![]() ![]() If the user wants to capture more values, increase the size of the array. It uses a first in, first out (FIFO) instruction, which is available in most of the more expensive processors. ![]() This is a method of capturing ten values into an array. If it is necessary to improve precision, a cyclic routine or interrupt can be used. One problem with it is that it is not going to be particularly precise since it operates within the scan. This is one method of creating sampling pulses that will work on pretty much any PLC platform, a free-running timer. After all, it takes time to process the signals and improve them. It is important to note that any modification of data collected will require a delay of the signal.
