Summary
Downloading to a PLC is a fundamental part of PLC programming. However, it is often considered to be a simple click of a button. This chapter has highlighted the important aspects of the download process that are often overlooked, such as the retention of data and methods to keep offline and online projects in synchronization.
TIA Portal always warns programmers of impending changes and will often require the selection of an action in order to proceed. It is important that habits are built by programmers to check the warnings and messages to ensure that the changes about to be actioned are understood.
In the next chapter, we will focus on the same principles, but for an HMI. This includes the configuration of connection parameters, downloading to hardware, and other important considerations.
