Operators can perform many actions in the iFIX run-time environment. When electronic signing is enabled in iFIX, operators may be required to electronically sign when they:
- Enter data that causes a change to the process.
- Acknowledge an alarm or a page of alarms.
- Manually delete an alarm or a page of alarms.
The need to sign for an action is determined by the way the associated tag is configured in the process database. When the application developer creates a tag, he can optionally require an electronic signature for the tag.
The application developer can configure a tag to be used by the following objects:
- Data links and text objects.
- Data entry forms, such as:
- Slider
- Ramp
- Alarm Summary object.
- Scripts that call global subroutines, such as:
- WriteValue
- ToggleDigitalPoint
- AcknowledgeAnAlarm
When these objects are used at run time to access a tag that requires electronic signature, the operator is prompted to enter the appropriate electronic signature.
