Support Alarms and Conditions

We are evaluating support of Alarms and Conditions for a future release of the AVEVA Adapter for OPC UA.

In order to get a better understanding of the user requirements and needs, please comment with the following of information:

  • How do you collect A&C data today?

  • How is your A&C data stored in PI?

  • What sort of alarm data do you have? I.e. instantaneous alarms, acknowledgements, alarms with a start and stop time?

  • What is the preferable way to create Alarms and Conditions within PI (i.e. PI Tags, Event Frames, etc.)

  • What is your best estimate for how many alarms/events should be created in a year?

  • What do you use to consume A&C data? How do you utilize A&C data afterwards?

  • How do you visualize A&C data?


The above information will allow us to build an A&C feature set that fits the needs of our broader customer base.

    • How do you collect A&C data today?

      • We use middleware to convert A&C to OPC A&E

    • How is your A&C data stored in PI?

      • In a PI tag as a string value combing different attributes into a single event

    • What sort of alarm data do you have? I.e. instantaneous alarms, acknowledgements, alarms with a start and stop time?

      • All events from the source system like alarms system events diagnostic events and audit trail.

    • What is the preferable way to create Alarms and Conditions within PI (i.e. PI Tags, Event Frames, etc.)

      • I do not know but currently we only have 1 issue and that is reporting events that have date time attributes. These are converted into text and are not easy to report in RtReports. It is not seen as time date anymore causing issues in converting this value to a time zone incl daylight saving time and sorting on this data.

    • What is your best estimate for how many alarms/events should be created in a year?

      • I cannot answer this because it is depending on the scope of the system

    • What do you use to consume A&C data? How do you utilize A&C data afterwards?

      • Data is used in RtReports and also for adhoc analysis with differnt tools.

    • How do you visualize A&C data?

      • Today we only visualize using PIVISION but these are results of events and not the events.

    An upgrade from a Read-Only to a Read-Write solution would also be useful.

    At the moment alarms and conditions are dependent how a user/administrator configures it in the PI System, most of the time based on tags and analytics. The adapter should allow to connect to OPC UA A&C and create Eventframes. The User/Administrator should be able to choose A&C attributes as EF attributes, as well as the primary referenced Element. If feasible, it should also be possible to configure the A&C as an subeventframe (e.g. subeventframe of a batch-eventframe).

    Speaking from process industry point of view (food, chemicals, pharma)

    -Alarms and Conditions are important to identify discrete events in time, imo this is just as important as the continuous data streams from metrology sensors. OPC UA adapters should be carrying all the features that the OPC UA A&C server is featuring.

    -A&C can represent: Process alarms, warnings, events. But also operator actions and audit trails. I often miss the capability to represent this kind of data in a out of the box / native way(without bespoke development) in PI Vision for example.
    -Right now we often need to connect to Relational databases to read A&E data, but that is not that evident since a lot of vendors don't give visibility into their data model, or have concerns regarding security and performance degradation of a RDBMS connection.
    -Another backside is that we end up (from this relational database from the source) with a lot of string text in the PI data archive, but there is no relation anymore between the events. eg there is no inherent relation anymore between an event representing an alarm that has come up and gone away/acknowledged, except for the text or some alarm ID in the string.

    -Also representation of A&E data is often via a custom solution. It would be great to have some configurable A&E element in PI Vision to represent alarms. I think way back there was something like the PI Alarm Viewer.
    PS
    --> obviously PI Event Frames can be used to configure and represent A&C, but:
    -we often just want a reflection of the A&E data from the source systems.
    -often this is just not realistic to create EF triggers for each possible source alarm

    In Pharma industry, my company utilizes Alarms and Conditions (for OPC UA) and Alarms and Events (for OPC DA) for audit trail logs for different equipment. We currently utilize multiple 3rd party vendors to collect these data. I am quite interested to utilize PI adapters, connectors or interfaces to move these data into PI, so that we have single data historian for all our data. I am quite interested to see what the PI Engineers/Developers come up with.

    Hi! We are about to do a pilot with alarms and events to let them be stored into event frames! I heared it was a new product from OSI regarding this issue! We want to be involved in a Beta test. We use Siemens WinCC and ABB 800 xA DCS systems. //Magnus Holmbom, Vattenfall Vattenkraft AB

    we also use WinCC and other scada systems. about what to collect/ not collect, there should be same filtering possible like in the scada system itself, so i want the possibility to filter on every attribute the scada system offers. Naming for event frame should also be possible. E.g. Asset_Alarmtext or Alarmtext_Messageclass,... The eventframes should be built without using PI Tags (Tagrefference). The behaviour of the end of eventframe (end eventframe when alarm is gone or with quitting) should be configurable in the connector

    Hi!   Currently we are using OPC AE and storing the events in Event Frames. When we move to use OPC UA we need to start to work with Alarms & Conditions instead!   Also i want a way to native create Event Frames within the Connector for OPC UA.   //Magnus

    hi we are using WinCC and other System as SCADA. Today we import the Alarm Data to an Pi Tag with the format String. The different colums from the scada system we sepaerate with a pipe symbol. For history this is fine. But in case of reporting and analytics this is very bad. I would be happy if there is an oportunity or a speicial pi point format for alarms. The nessary coloums are: - Alarm ID - TimeStamp - Location - Messagetext - Duration - Status (Start, End) - Class

    We would appreciate if there would be a possibility to choose between Event Frame storage and PI Tag storage, or even both at the same time.

    For the moment we work with the OPC A&E interrface to get alarms out of Siemens WinCC, but that is not very fexible. So the OPC UA connector should have at least the same functionality, preferable more like eventframes for alarms, one PI tag for all the messages, ...

    Seconding Yusuf Cördük's comment, it would be great to have the option to choose between EF storage and PI tag storage for the Alarms and Conditions. Our end users prefer to have the Alarms data as strings in PI tags.

    Alarms and Events data from automation systems become more and more important to store for long term. This demand comes from the need to optimize processes through data analytics and data modeling tools. Ideally this Alarm & Condition data is store in the same data repository as trend data. Moving from OPC Classic to OPC UA is key as we have systems that are not providing the OPC Classic interface. When the PI connector is not supporting the Alarm capturing, we'll need to setup other systems that does provide the OPC UA Alarms & Conditions and long time storage capabilities.

    OPC UA Alarm and Events retrieval is an important feature that i would like to see in PI, there are different business partner that invested resources to update the shoo floor equipment to allow OPC UA connection, so i consider the unavailability of A&C a gap of the OSiPi system.

    Customers are telling me that in pharma, they've reached the inflection point where vendors are only offering OPC UA. Before when vendors' UA server was a wrapper, they could always get to alarms with OPC A&E. That's no longer the case, and they now must access this data from OPC UA Alarms and Conditions or they aren't going to get it. This is vital for operations as alarm history is required in pharma manufacturing and we've historically had products to get this data.

    OPC UA A&E is a must as this is used in control systems to capture batch exceptions which then need to be captured and reported using RtReports.

    What is your primary use case for collecting A&C data? We use the A&C data for troubleshooting, root case analyses and continous improvements! o How do you collect A&C data today? We use the OPC AE Interface. o How is their A&C data stored in PI? We are currently investigating if we can store it in event frames. o What sort of alarm data do you have? I.e. instantaneous alarms, acknowledgements, alarms with a start and stop time? We have all of the above alarms! o What is the preferable way to create Alarms and Conditions within PI (i.e. PI Tags, Event Frames, etc.) Preferably it has to be stored in a relational database, maybe as Event frames. I think if the adapter can create event frames would be the best! o What is your best estimate for how many alarms/events should be created in a year? We have 10.000.000 events per year and rising! o What do you use to consume A&C data? How do you utilize A&C data afterwards? We use it when a failure occurs in our plants for trouble shooting and root cause analyses. We also plan to use it as reports! o How do you visualize A&C data? We are trying out PI Vision Events list but are not really satisfied with the performance and flexibility. Also reports can be created in Power BI using the integrator for BI.

PI Adapter for OPC UA should be able to capture alarm and events (A&E)

Merged
OPC UA Servers now implement A&E, especially in the Life Sciences industry. We need to be able to capture these into PI tags using the PI Adapter for OPC UA technology.
