Understanding how scanning works in a programmable logic controller (PLC) is something that needs to be addressed for a user regardless of the program being used.
From minor modifications to major overhauls, an automation system will significantly change during its lifecycle. Good planning, research, and following these guidelines can ensure a successful upgrade.
Once values from an analog card have been captured, there are methods to filter the data and methods to simulate a filter using Microsoft Excel before it is coded into a PLC.
A programmable logic controller (PLC) is designed to not only provide information on signal levels, but it can also capture data and it can be analyzed, but there are a number of challenges the user faces from a software and logistical standpoint.
Part 2 of this 2-part series covers preparing the dataset for training, neural network model training and validation, implementing a neural network model on a control platform, and human-machine interface (HMI) requirements.
