Narrow the scan scope

Limit by PLC, DB-number range, or DB branch in the project tree. The main window can scan all proven standard-layout DB members or further retain only members marked HMI/OPC accessible.

Step 3

Step 3: Narrow the scan scope

Narrow the scope before a full project scan to improve speed and review efficiency.

Available scope controls

Limit by PLC, DB-number range, or DB branch in the project tree. The main window can scan all proven standard-layout DB members or further retain only members marked HMI/OPC accessible.

Use the standard-DB scope

Choose all proven standard-layout DBs or keep only members explicitly marked HMI/OPC accessible, then narrow by DB number, PLC name, project tree, or excluded-name rules. I, Q, and M are outside the current scan scope.

What belongs in excluded names

Use excluded-name rules for backup, history, temporary, simulation, retired, or non-delivery naming fragments. Keep each rule reviewable and avoid short fragments that can remove unrelated points.

Why narrowing matters

Large projects can produce many irrelevant points. A smaller first scan makes it easier to confirm the rule and address pattern.

Suggested approach

Follow these steps, verify the result, then expand the scope.

Start from one PLC
Select only required tables or DBs
Run a small initial scan first

DB-number range syntax

Included and excluded DB ranges accept a single number or a continuous range, such as 1, DB1, 10-20, or DB10-DB20. Include ranges define the main scan set; exclude ranges remove DBs that should not be delivered. A range applies only when TIA metadata supplies a recognizable DB number.

Project-tree scope comes before rules

The project-tree selection defines what is scanned; rules operate only on the points that were scanned. An unselected PLC, table, or DB cannot be added back by a matching rule.

HMI/OPC-accessible scope

The HMI/OPC-accessible option checks member access attributes inside standard-layout DBs. It is not an online OPC scan and does not add optimized DBs or I, Q, and M areas to the result.
