I have a simple problem where I need to report the amount of specific events that have occurred within a time frame. To achieve this I have implemented an Event Frame to detect these events and I was hoping there would be a way to simply count the events triggered by my created Event Frame. I would most preferably like to achieve this in DataLink as I do not necessarily need to keep historical data of the events through a PI tag.
Any help would be appreciated.
I am very new to PI and am trying to keep up with the demand. I try looking online but there is too much data for someone new to sort through.
I've been asked to take 4 tags and calculate the data from the past 24 hours and then add them all up.
I have been successful in calculating the total of several tags but not in calculating the tags based on the data from the past 24 hours.
Any help would be appreciated.
I tried:
Total('SE65BH__0612ENWT','*-24h','*')
TagVal('SE65BH__0612ENWT','*-24h','*')
What am I doing wrong?
Once I get this one tag in the calculation working then I will work to get the others added in.
Thanks
I would like to download a copy of a pi database (2000 tags) into a excel spreadsheet with tag name,descriptor and a snapshot of the data.
I can do a tag seach nd get all the tag names - how do i getthe rest.
thanks in advance
Hi all,
I have an issue in the communication between PI Server and OPC Server.
After many test we have found this trouble occurs each time OPC Server Machine is restarted. Because the user and password configuration in OPC DCOM is missing and communication fail(all tags become Timeout state).
To fix temporaly the problem we have to execute dcomcnfg.exe windows tool, navigate to Component Services | Computers| My PC | DCOM Configuration and search OPC DCOM item. (Right Click), click on Identity tab and fill user,password and confirm password in this user radio button. Yoy can see details in the snapshot attached below. It looks as whether all user and password configuration parameters disappear when OPC Server reboot.
With this solution communication is restablihed until an inesperate or controllated reboot happens.
Could you please help me?
Thanks in advance
I'm trying to use some VBA to make it easier for users to print trends from a Processbook display. With all the different monitor formats these days, it's tough to get a trend that fills a page nicely without lots of blank space. Also I have some VBA controls on the display next to the trend for simplified tag searching and trend config and I don't want those to appear on the printout. I wrote some VBA to dynamically resize the display to one with the correct aspect ratio for 8.5x11, maximize the active trend to fill the display which hides the VBA controls, print it, then un-maximize and return display to original size. This works well except when maximizing the trend, Processbook automatically includes the server name in the tag list on the right hand side and the tag list ends up using ~30% of the sheet of paper. I have the legend set to not display the server name when the trend is not maximized, but it doesn't seem to carry through. Is there any way to change this default behavior when maximizing the trend?
Also, if anyone has other suggestions for making trends easier to print for end users, it would be greatly appreciated? I don't see a Trend.printout method in the ProcessBook SDK, just Display.printout which does the whole display including the VBA controls. If anyone knows a way to directly just print a trend so it is scaled to fit to a 8.5x11 sheet, that would be very helpful.
Thanks,

Hi,
I want to store PE tag value at the frequency of 2 min. I have checked pipeschd.bat and found the default configuration
Good Morning all, I am new to PI and am hopeing someone can help me with a question have.
I am trying to set a up attribute to return a value if an expression is true.
If i were to want to do this in excel it would look like so
=if("pi tag" =0,1,0)
How would i complete this in pi AF?
Thanks
Josh
Morning all, i am looking to try and complete a time filter of a tag in AF.
I would like to know the total time that a pi tag is =0 in a 24hr period. Is this possible in AF?
Thanks, J
Hi all,
I have created a totalizer as:
Counts Event, setting Time when True, block and equal to 1.
My goal is to count how long a signal is set to 1 and with this configuration the totalizer is working properly counting how many seconds the signal value is 1.
But I need to display the result in relative time with this format hh:dd:ss instead of only ss. I tried changing Totalizer Point Type to Timestamp but the result is shown in absolut time from 01/01/1970 01:00.
How can I get to express, for instance, 5400 like 1:30:00 using Totalizers?
Thank you in advance.
How can we rearrange the sequence of Attribute for a element in AF or Need a Specific sequence (such as Sr.No,Date, Name) in a notification content.
This content will be passed to xml file created by a Notification.
We have five (5) PI environments, we have this many to build on interface software that would look at PI and AF for data and information. Our source of truth is our Production environment and this is what we clone to populate the other development environments. The problem arrises when we clone AF and PI tags and populate the other environments with this content. Even thou the servers names are updated in the AF file and tag and security are exactly the same as Production the MDB to AF sync refuses to sync. It might start off and make an attempt but it rarely over time completes.
Has anyone expereinced problems with the sync process, had to transfer between multiple environments and how might you have resolved these challenges?
We have a 32 bit Pi server containing some archive files( less than 10 Gb). We have installed a new 64 bit PI server along with a new data server running the project ( Rockwell Data Server)
Our plan is to run both servers side by side - so all the data from the 32 bit PI server is migrated/ transferred to the new 64 bit PI server. Both the 32 and 64 bit server would continue to run in future and store historical data.
I have tried backing the data from the 32 bit system to a external medium and transferred the files to the new 64 bit PI server. The tags were missing so i have to use excel to import the tags into the new machine i think but not sure.
What is the easiest way for getting the data from the 32 bit systems to the new 64 bit PI server. Pls advise
good Morning
I need to charge the ListBox1 from excel file with clik on button6

Hi to Everyone
I'm trying to apply a PI formula into excel spreadsheet with VBA by this code:
How can resize automaticaly ??
Thanks
I'm trying to make a trend template that lets users do some simple Processbook config all in runtime without have to switch to config. mode and double click the trend.
Currently I'm working to give them a way to change pen colors to a few pre-selected higher contrast colors using VB comboboxes, etc. Does any one know if there is a way to change a pen color without using the .SetFormat method?
While working on some VBA to simplify printing the display, I noticed that the .SetFormat method appears to clear out the cursors. I was using that method to temporarily change the display background from the default grey to white for better contrast on paper (and to save toner!). I wrote some code to capture the cursors and reapply them, and it's not a big deal to do, but I wanted to see if anyone knows if there is a way to prevent that from happening in the first place.

I have 276 AF attributes (from 46 AF objects) for which I want to change the data reference type from "none" to "PI Point". How do I accomplish this without making changes to the template? I am not sure if Datalink can be used since it allows me to search only one object at a time. Am I missing something here?
Any assistance is sincerely appreciated.
Thanks,
Arti
Hi all,
As part of my job I started working with PI and AF.
One of my requirements is to make production accounting data from Tieto Energy Components (EC) accessible by Processbook.
Please correct me if I’m mistaken on any of them but it seems to me there should be several ways to accomplish this:
If you could point me in the right direction that would great thanks
Cheers,

Hi,
I am working on a custom .NET application (Windows Service) that uses the AF SDK (PI AF Developer Tools 2014 R2 v.2.6.1.6238) to query AF/PI and save data into SQL Server on a polling schedule, however sometimes the queries seem to lockup/timeout - no timeout or other exceptions are thrown - the call just seem to hang.
I have tried setting the PISystem.ConnectionInfo.TimeOut value to a low value (e.g. 2 secs) and nothing seems to change in the AF SDK behaviour.
I have looked in PI-SMT Network Statistics and the process seems to be working correctly... no errors are showing for the connection.
If an exception (TImeOut or otherwise) were thrown, I could at least handle that - do some recovery and try again.
Has anyone come across this before and found a solution?
Kind Regards,
Mark
Very new to PI and need some help.
I have two EXACT same tags - one just shows the current value and the second one has a calculation in the Exdesc section but for some reason both tags show the exact live value and I was hoping the second tag would should the calculated value. I am not sure about the total code section. do I need to have this set to 1 for it to process the code? I tried it at 1 for the past 30 minutes and originally I saw a different value but then it changed to Scan Off and never showed again.
Anyone with basic advice for someone struggling?
Thanks
