"Write value" on Live > Tag is not available for my user

[HMIDesign]

During commissioning I want to test a few PLC bits from Proveris, for example resetting a counter tag after a trial run. On the LIVE > TAG page I can see the values updating, and a colleague told me there is a "Write value" action in the Action column. On my account I can't use it.
My user is a Manager. Is writing to tags a licensed feature, or is it a permission problem? And are there any limits on which tags can be written? I don't want to accidentally write to something critical on the line.

[Technical Support]

This is a permission setting, not a license feature. Writing a value from LIVE > TAG is only open to users with the Developer role. Manager and Operator users can watch values but not write them. That's intentional: a write goes straight to the device on the shop floor.
To get access
Ask whoever administers Proveris to change your role to Developer on the USERS page, or create a separate Developer account that you only use for commissioning. We recommend keeping the number of Developer users to one or two.
How the write works
1. Click Write value in the Action column of the tag.
2. The Write value to tag dialog shows the tag name, data type, protocol and current value.
3. Enter the new value. For boolean tags you choose On (1) or Off (0); for numeric tags the allowed range is shown.
4. Click Continue. A confirmation step follows that warns you the value will be written to the device (PLC) and a wrong value can affect the machine.
Which tags can be written
Only tags on writable protocols, such as Modbus TCP, Modbus RTU, RTU Over TCP, MQTT and internal tags. Tags that are read-only in the PLC will still be rejected by the device.
Good practice during commissioning
- Write only to tags you have agreed with the PLC programmer.
- Avoid writing to tags that start motion. Use dedicated reset or test bits.
- Every write is logged; you can review it later under Report > Event Log.
