Signatures for Device Dataset Changes

ABB Field Information Manager Learning Center

Signatures protect device datasets from unauthorized changes.

Users with "Full Access" can configure the signature level per device via Device Tile Context Menu - MORE - SIGNATURE LEVEL.

The currently configured signature level is displayed in Configuration View and every device dataset change is protected accordingly.

Signature Level Dialog

Note:
Plugins can change datasets, thus the signature workflow is performed before opening a plugin (UIP) to protect the device dataset against unintended changes.

Note:
Entered signature information (e.g. reason for change and approver name) is included in Audit Trail events (e.g. Parameter Change, Send to Field Device).

No Signature

Device dataset changes require no further authorization.

Note:
The default signature level for devices is "No Signature".

1-Factor Sign Off

Any change in a device dataset (e.g. via DEVICE SETTINGS or SEND TO FIELD DEVICE) requires an authorization by the currently logged-in user.

Before applying the change to the device dataset, a signature dialog is opened, requesting the correct password from the user and a reason for change in text form.

The change in the device dataset is only performed if the authorization is completed successfully.

Signature Level 1-Factor

2-Factor Approval

Any change in a device dataset (e.g. via DEVICE SETTINGS or SEND TO FIELD DEVICE) requires an authorization by the currently logged-in user and a second user as approver.

Before applying the change to the device dataset, a signature dialog is opened and the 1-Factor Sign Off is performed. In addition, a second user must approve the device dataset change with user name and correct password.

The approver must have at least Write Access to authorize the device dataset change.

The change in the device dataset is only performed if the authorization and approval is completed successfully.

Signature Level 2-Factor
