Dear Engineer,
I'm actually fighting with Alarm Acknowledgement for a specific Project. Our Customer wants to implement specific alarm Priority, with specific Acknowledgement rights.
That means in the AI block I added a Alarm Block with 6 new alarm level and higher Priorities. This alarm level are enabled/disabled via faceplate, one Check box per level (HI, HI_HI...) and one push button to active the monitoring.
This works well, but the customer wants to use Electronic signature to Acknowledge ONLY this new alarms.
I've added a new Signature Policy with Field Confirmation / Field Name: NALM / Signature Required: Confirm and Verify.
But this Policy is applied to the whole AI Block. Is it possible to assign a Policy to a specific Alarm ?
I've found no help in BOL.
If somebody knows where I could find useful information about Electronic signature, with different Examples and screenshots....
Regardless of the question above, is it possible to Acknowledge one single alarm eg: PT100_HIHI with a push button on the display. A vba code example is welcome
Thanks a lot.

Thank you.
I simply added in the new alarm name in the tab "Parameter Confirmation" in my ES Policy, with "Confirm and Verify " as signature required.
That works fine, but a new problem appears
Example:
5 alarms which require confirmation are active.
The Operator acknowledge them through "Acknowledge All" Button on Alarm Summary Display.
The confirmation pop up appears only one time, and not 5 time how I expect.
I need one confirmation per Alarm (which require confirmation) , how could I resolve this problem?
Thank you for your help.

Hello,
we've implemented the E-Sig as describe above.
We are facing a dicrepancy.
1) HI_HI_Alarm is Active
2) The Operator Acknowledge via Acknowledge All onnfaceplate
3) The E sif Pop Up appears.
4) The operator write a comment and confirm with ID and PW, but the PW is wrong.
5) We expected that the aknowledgement is not confirmed.....But it is not the case.
Please could somebody explain me the logic?
Thank you for your help
E-Sig config:
2) The Operator Acknowledge via Acknowledge All on faceplate

Hello André,
thank you for your help.
This problem happens on the plant (with Operator capabilities).
I've made the print screens on my test station, that's why the user is ADMINISTRATOR.
I've tested an other way to acknowledge, instead of using the "Ack all" button on the Faceplate, I've simply click on the single alarm, on the Alarm Summary on the face plate.
An E-Sig pop up appears with another design (the same as if you write directly the variable in Control studio), and if I press OK with a bad password nothing happens!
The Alarm is still UNACK, that is what we need.
The system also react differently with "Ack All" and the single Alarm Ack (Faceplate on Alarm Sum.).
I will contact our Emerson Support. If somebody knows something thank you for sharing your information.
Kind regards
Christophe.
