One of the most critical steps of PLC programming is creating back-ups. This step is present at one form or another within every facility or machine builder in this world. Some programmers will save a file on their laptop, some will save a copy on a shared drive, some will rely on a server that runs FactoryTalk Asset Centre and others will utilize the SD Card feature of the current PLCs. Although it’s not the most reliable way to create a backup, it can be the most cost and time effective way to store a back-up in a small facility or a way to migrate the same program onto multiple machines.
