Today’s manufacturing industry depends on Programmable Logic Controllers (PLCs). Throughout the industry, engineers are using these PLCs to collect and keep track of vast quantities data. There are many different ways that the industry uses to accomplish this task of retrieving and reporting useful data out of the PLCs. End-to-end transfers use large application tools, others use open software, and yet others use proprietary solutions. Incorporating laboratory instruction on the handling of such transfers in an educational laboratory has value. Making such capabilities available for senior project work has value. This project considers two very different strategies of monitoring and collecting PLC data for student instruction.
First considered, is the use of free demonstration software to implement an Industry standard solution that works with a broad number of devices. The software includes, but is not limited to, OLE for Process Control (OPC) software interface standard devices1,2.
Second considered, is the use of a proprietary application solution that provides a data logging tool enabled through its proprietary communication standard.
In each case, the data traffic source is a PLC. The data traffic destination is a Windows 10 computer. The PLC and PC share a LAN connection. All data traffic is over Ethernet.
The paper describes the setup of each strategy and ranks them for usability. The study looks at the positives, the downfalls and the limitations of each and estimates why one would be more appealing over the other. The study considers the ability of each to meet needs of PLC curricula and the need of PLCs in senior project and capstone courses.
