Merry Christmas and Happy New Year, your videos are insightful and helpful to the PI community, please keep up with your wonderful videos, thank you very much!

No one knows PCS7 inside and out. Been working with it for 10 years every day and only know about 40%.

Thank you for all your informative videos and helpful tips. Happy New Year!

Great video, Ricky!

Hi Ricky - In October we released AVEVA PI Server 2024. This includes a major overhaul of the PI Update Manager on the Data Archive to be able to support the massive demand of PI Analytics during this use case. Alleviating these types of issues is one of the releases' goals. Have you been able to upgrade and test this in your scenario?

A few comments to perhaps clarify some of the items discussed in this video. When an analysis is first started up, PI Analysis Service signs up with the Data Archive for updates for any PI Points that are involved with that analysis. This is so that if a PI Point value changes, PI Analysis Service would know to perform some tasks. Imagine you have 2000 analyses with 100 PI Points in each element involved with an analysis, that's a lot of PI Point and work to sign up with the PI Update Manager. Now when you change template, PI Analysis Service would send requests to PI Update Manager to drop all the previous signups, then re-signup all the PI Points used in the new template. This is necessary because there's no way to know if the same PI Points are used before/after the template change. In addition, for time based aggregations, the initial starting point is when you turn on the analyses so it's necessary to refresh the data cache with the proper data. This is where the bottleneck is in your scenario. Fortunately PI Server 2024 has targeted improvement to PI Update Manager that should alleviate some of this bottleneck. If you have access to the new release, it's worthwhile to give it a try.

Hi Ricky, Do you have expertise on PI Adapter for EventHub

This issue has affected us as well and all we could do is restart the service again and again till we get frustrated.

thanks for the video. i am trying to access PI historic server, could you suggest some best option please

Great video, Ricky!

Thank you very much for the contribution. Can you make a video on how to recover deleted points?

Greatly explain thanks !

Hi Ricky, do you have any code references on how you connect to PI and get data?

@ricky, If we go with odbc or webapi connection to adf, can we ensure real time data streams or it would be schedule based refresh of data

Old pie worked great, was very very easy to use! New aveva pi is absolutely user unfriendly. Why did the take to ease of use away! This new version is like the failed update from windows 2001 to Vista! You made it almost useless from a plant operator stand point!

Please release part 2 😊😂🎉

Hello ricky, can we get multiple values in a single tag from database table.

Informative video! For your information, Ignition MQTT has Store & Forward mechanism to make sure you don't loss data if the primary client (OSI PI in your case) is disconnected from the broker (MQTT Distributor Module in Ignition), the broker notifies the publishers (usually in your case the MQTT Transmission Module in Ignition), so the publisher starts to store all the data timestamped, until the connection is reestablished, then it will starts to sync and push the stored data with the timestamp (with balance to not overload the traffic) to fill the gaps. I know it's not like sync historical data in OPC UA, but I think it can cover around 80-90% of the cases and needs.

This is very helpful on the things to consider especially to save and optimise the PI tags count moving from unlimited tags under EA to Flex.

Can you discuss more on PI DATA HUB.

For small budget companies, take a back-up of tag configuration, historical data into a file and move them to other machine. Then disable the tag and delete it after a quarter. If we need it again, go back to import to PI SYSTEM.

Thanks for putting effort to create this video. Can I please ask you a couple questions: 1. Could you give an example of how to send a request to get PI points using postman. for example , what's the base url if I only know the PI Server name. 2. The configuration screenshot you show in your video, I don't see that configuration page at all when I'm using PI system explorer, could it because of my access level? For example, only privileged user can access that page?

So pi notifications don’t support sms natively right ? I know top view have that

Even do the DA is more faster, but what about the data loss? HDA teoratically ensures that we won't have data loss. Correct me please if I'm wrong.

You should do an interview with one of the ex-OSI folks who is at Databricks now!

Intresing story, I hope she will be good in the long run. I'm a bit sad because I thinked there will be some parallel in the story with the PI World.

Hi Ricky. Thanks for the video! Can you please elaborate more on why it is a bad idea to install the latest version? Thanks!

Great Video Ricky! It's great to see your face on here!!!

Yes job interviews are very stressful and at least 50% of what the interviewers are looking for is how well you can communicate when under pressure as they want a team player as much as an expert in some technical field. Nice video, very humanising and a good topic for people new to the job market. I look forward to watching more.

Congratulations Ricky Sun! 👏🎉 Your video was truly informative and on point. Your thorough analysis shed great light on the complexities and benefits of switching to AVEVA DataHub. It's fantastic to see how you break down technical topics in such an accessible and engaging way. A big thank you for sharing your knowledge and passion with us! 🙏📊

There is definitely a lot of freedom being a contractor and not to forget you can take as much time off to travel as you like.

Nice video and explanation of this situation, Ricky.

This is a great overview. It isn't easy for users to understand the new landscape and how the parts fit together or what use cases are appropriate. Have you signed up for developer access to ADH yet? I've had access in the past, but haven't played with anything recently. I think having some industry veterans kicking the tires and slinging the bits in some demos will definitely help people understand the newer technologies and how they might help them solve some of their pain points.

Ricky, thank you for taking this video in Aveva World. I believe open source plus cloud service will change the data historian industry. My dream is to make TDengine, the next generation data historian, affordable and accessible for millions of enterprises from startups to giants.

I thought AF is the replacement all a long. Thanks for the info

Hey Ricky, I have paid my own way for 7 years now. IAfew years I have got free pass because I was a speaker. I have not regretted it one bit. I think you have the right attitude and will get a lot out of it! See you there - Lonnie

Just found your channel Ricky! Awesome job on the videos!

If the OPC server updates the tags and if the tags still won't update in PI, I would just turn OFF and ON the scan. The good old alternative to restarting the interface instance. Ideally the grouping of tags into different interface instances and scan classes is very important to avoid such issues.

Could you please make a videos on PI accreditation certification??From register to certification to what kind of questions we get in final exam???

Excellent Ricky. Good job. I'll have on count

Superb Ricky it was really helpful

Thanks Ricky really helpful

can sms notification be created in bulk? In PI Builder or anywhere else. Pls suggest.

Are you aware of any part time/side gigs you can do as a PI consultant? Or does these sort of jobs not exist in this industry(kind of like freelance work, maybe while also having your fulltime job)?

Valid çomments. Good work.🎉

Inspiring

Good insight. Thanks

Thanks for sharing, Ricky

The margins are never this thin for a company and the employees are usually asking for relatively small increases 5-10%. If they do their job well and occasionally go beyond that there is no question they merit an increase. Large employers have very large margins per employee so their ability to give raises is large as well.
