Computers have memory, microcontrollers have memory, and programmable logic controllers (PLCs) have memory. However, memory is a very complex topic that many automation engineers often take for granted. Typically, most automation programmers have an if it can be uploaded to a device, it’s fine mentality. This mentality can get a person through their day-to-day activities, but it will hold them back in the long run, especially when more complex topics such as pointers need to be utilized.

Memory is a complex topic that can often baffle inexperienced developers. Memory has hardware aspects and software aspects that have to work in unison for a device to effectively function. The concepts that govern memory can often be very confusing for those who are not well versed in computer science, and as such their...
