When building an FB that contains sub-components (for example, a Valve Pack FB that controls five individual valves), do not assign a separate Instance DB to every sub-valve. Instead, declare the sub-valve FBs inside the static tag interface of the parent Valve Pack FB. This embeds their memory inside the parent block's DB, creating a clean, single-DB architecture known as a . 6.

For advanced systems containing multiple identical assets, TIA Portal supports . By altering an index variable based on operator selection, a single HMI faceplate screen dynamically rebinds its graphics to read from different data blocks (e.g., switching from Pump 1 to Pump 2 data seamlessly).
