This weeks Q&A is a quirky question about Tags and Function Blocks

If we have Function Blocks and their instance data, why do we need tags?

Well the truth is, they're completely different in TIA Portal and have very different uses....

Hopefully this question helps distinguish the differences on where these Tags and FB data are used

Latest Tip

Bespoke variables are frequently adjusted by opera Bespoke variables are frequently adjusted by operators through the HMI. These values define process behavior and must persist across power cycles.

In TIA Portal, retention is applied at the structure level. If it is not enabled, all values inside the structure reset on power loss, regardless of intent.

Treat retention as a design decision, not an afterthought. Understanding where bespoke data lives and how it is stored is critical for reliable, maintainable automation systems.
