Asking for your help on why PI UFL tag is having an in and out value discrepancy from the source UFL file.
Here is an example of the discrepancy:
Does i have to configure some settings in UFL?
As per the data provided looks like it is rounded to the nearest integer. Is the data from PI is compressed data or sampled data?
Could you please share the configuration in UFL and screen shots from data archive and source file?
this is my updated issue. I already editted the UFL ini file but when i already run it. Theres still 1 value having disrepancy in each timestamp. already turn off the compression.
attact the INI File. I have two Message type because when csv files were already dump in folder, theres no timestamp for 12 Midnight. but anyhow its still works. Just only the discrepancy values.
attach my sample CSV File
Hopes you could help me with this.
What is the pointtype in PI?
Also, does it only happened for your integers? Seems like you are defining everything as Float (Number) in the INI.
yes it only happens for the integers. All my tag pointtypes are set in float32.Did i miss something on the configuration of point type for the tags?
The values seem too far off to be rounding, but unless you are expecting floats, I would change the data type in PI and in the INI file: FIELD(x).TYPE = "Int32"
So im going to change thr data type on the tag that is having issue. Thanks for the help. Will keep you posted regarding this, will try this later.
Already tried your advise. I just change that data type those have no decimal place. I change it from float32 to int32 for the PI and number to int32 for INI file. But it seems i get the same value that i posted in the previous screenshot. Already turn off and on the compression. Already disable/enable the exception. Tried different data type in PI but still coming up in float32/int32 choices only. Yet still getting the same discrepancy.
I can't really see the interface being the issue here.
Thanks for assisting me on this.
My datalink version is
Current configuration of the tags
For Ini File: (number and int 32)
For PI Tag: (float32 and int32)
While checking the archive editor values still not the same.
Then i configured buffering Manager to check also the logs, when checking the values that it receives are correct.
I dont know if the issue is between pi buffs and PI DA. but my screenshot from the PI Message logs coming from the PI UFL seems correct but when archiving it in the PI DA already have discrepancy.
I am too facing the same issue, I tried to troubleshoot using the above responses but it didn't work.
One thing that I can confirm from the interface log files (debug level 6) is that the interface itself is reading incorrectly , the value is 500 but the interface reads it as 500500 and then writes the same value to PI DA
Please let me know the solution and also if this is a known issue
I would suggest opening up a ticket with our Tech Support team and providing:
