Installation Steps

1. Download the file using the green button above. The permalink always serves the most recent version.
2. Close TIA Portal completely. The Add-In cannot be replaced while TIA is running (the DLL is locked).
3. Copy BlockParam.addin into:
   C:\Program Files\Siemens\Automation\Portal V20\AddIns\
   Windows will prompt for administrator rights — confirm the UAC dialog.
4. Start TIA Portal. On first load it will ask to trust the Add-In — click Yes. The Add-In appears under Options → Add-Ins.
5. Activate the Add-In in the Add-Ins panel if it is not already enabled.
6. Use it: right-click any Data Block in the project tree and select "BlockParam...".

First-Run Checklist

After the Add-In loads, you can try it immediately with no configuration:

• Right-click a Data Block with nested UDTs → BlockParam...
• Try the "Show setpoints only" filter to see the value members
• Select a member, pick a scope level, enter a new value, click Set (yellow staging)
• Review the pending changes, then click Apply (or Apply & Close)

Upgrading to Pro

The free tier is limited to 3 bulk operations and 50 inline edits per calendar day. To remove those limits, buy a Pro license — then follow the three activation steps below.

1. Receive your key. After checkout you'll get an email with a license key in the format PRO-XXXX-XXXX-XXXX.
2. Open BlockParam. In TIA Portal, right-click any Data Block and choose "BlockParam...". At the bottom of the dialog, click "Enter License Key".
3. Paste & activate. Paste your key and click "Activate". The status changes to Pro and all daily limits are removed.

FAQ / Troubleshooting

The context menu entry doesn't appear after installing.

Go to Options → Add-Ins inside TIA Portal, locate BlockParam, and toggle it to Active. Restart the project view.

TIA Portal refuses to load the Add-In with a trust warning.

Confirm the trust prompt on first load. If you accidentally declined, remove the entry from Options → Add-Ins and reload the project.

How do I uninstall?

Close TIA Portal, delete BlockParam.addin from the AddIns folder, restart TIA Portal. Your license data in %APPDATA%\BlockParam\ can be deleted manually if you want a clean wipe.

Where are config and logs stored?

Config: %APPDATA%\BlockParam\config.json, logs: %APPDATA%\BlockParam\logs\, rule files: %APPDATA%\BlockParam\rules\.

Can my team share rules?

Yes — point rulesDirectory in config.json to a shared network path. Local rules override the shared ones on conflict. See the configuration docs for details.
