    Isn't the use of suppression in a flood condition intended to be a "tacit" acknowledgement of multiple alarms? If the individual alarm triggers outside of the condition that caused the initial flood, when suppression is removed then I would assume it acts as a new alarm.

    Another one I've seen... Does the latest Analyze 4.0 backward compatible with all the previous versions of DeltaV?
  • In reply to GeloCortez:

    latest version of deltaV, is there a way to have separate list for AUTO suppression and MANUAL suppression? currently what we did is to change the alarm priority to "Disabled" for auto suppression and created an Active control to segragate auto suppression from manual
  • In reply to Michael Moody:

    Michael,

    In the latest release of DeltaV Analyze, V4, you can explicitly specify the alarm priority range in the KPI reports.

    In V2 through V4 of DeltaV Analyze there is another built-in filtering function that excludes alarms in new alarm counts if the alarm is assigned a priority that is set up for automatic acknowledgement. The idea here is that if an alarm is automatically auto-acknowledged it's optional for the operator to respond to and thus an alert as far as KPIs are concerned.

    Unfortunately I will miss Austin on account of our shutdown here. I know people are looking for more than just suppression for states - like enabling certain alarms that are only used during shutdowns and changing setpoints, and then setting them all back to "normal" when the outage is over.
  • In reply to Matt Wicks:

    Matt,
    If the alarm wasn't active when the flood occurs but the alarm gets suppressed, becomes active active while it is suppressed, it will still come back as Active and Acknowledged when suppression is removed. This is how the product works with suppression.
  • In reply to Jim Cahill:

    Not to be left out: ISA 18.2 clause 3.1.46 defines "Instrument diagnostic alarm". This is for device problems. Such alarms can be managed through NE107/PlantWeb Alerts to ensure operators only get alarms for device failures that will have an immediate effect on the process, not nuisance alarms for device diagnostics which is predictive, failures that will happen far into the future - which only maintenance needs to know about
  • Common question I've heard about ISA. Q: What are the main differences between the 2016 version of the ISA-18.2 standard and the 2009 version?

  • In reply to GeloCortez:

    Yes there is a way to do this in v13. The auto suppression can be done using the OOS on the alarm and the operators can use the Shelving (old Suppression). Then with the new alarm summary filters you can create two display with Manual Suppression and Auto Suppression to separate them. If you don't separate them you can still tell by looking at the Shlv timer and if this is blank, then suppression is OOS.
  • In reply to Rachelle McWright:

    The two versions are largely the same, however, there are some key differences that end users, integrators and suppliers should be aware. Firstly the definition of an alarm now includes the word “timely”, as in “an alarm requires a timely response by the operator”. This change synchronizes the definition with the international version of the standard (IEC 62682).

    Additional topics were added for discussion / documentation in an alarm philosophy document. The philosophy is now required to address Alarm System (Management) Audit, Alarm Design Guidance, and Alarm Response Procedures. It is recommended that the philosophy document how you plan to use alarm shelving.

    Speaking of alarm shelving (a form of manual alarm suppression)..The standard now dictates that alarm shelving is “required” functionality. This is good news for DeltaV users because alarm shelving is built-in and provides many options for how it can be applied.

    I would like to know what best practices are recommended with regards to "Off Delays" time as a default.
  • In reply to Jim Cahill:

    DeltaV Analyze 4.0 is compatible with DeltaV 13.3.1 and 12.3.1. If you are using DeltaV 11.3.1, you will need to use Analyze 3.0. To get Analyze 3.0, you can buy Analyze 4.0 and download the 3.0 installation media from Guardian.
  • In reply to John Rezabek:

    John,
    This module has been designed to have the ability to change (or don't change) the Enable, Priority and/or Limit based on when the "State" changes. The module needs a single state parameter to exist somewhere (either external or in itself). Sounds like you will be very busy so when you get some time I can give you a quick demo via Webex.
  • In reply to Matt Stoner:

    thanks matt for the response, currently client is on version 12.3. we'll keep it as it is for now.
  • Hello all, sorry for the late entrance. Doing a quick read to catch up.
