When you are creating SQL Select, Insert, or Update statements for your VisiconX data control in iFIX, you have the option of requiring electronic signatures to be used for these commands when WorkSpace is in run mode. You can apply Perform Only or Perform and Verify signatures to your statements.
When your data control is opened in run mode, you are prompted with the Electronic Signature login dialog box. When you sign in, a message is sent to the iFIX alarm system. If the signature is valid a successful signature message displays. If the signature is invalid, an Invalid Esignature message displays.
For more detailed information about using electronic signatures, see Using Electronic Signatures.
These electronic signatures are provided for added security. For example, if you are changing data in a database and require those changes to be audited. You can access the audit trail from the same esignature audit trail that the other iFIX esignatures use. For more information, see Creating an Electronic Signature Audit Trail.
