Eyal Koren Posted June 22, 2014 Report Share Posted June 22, 2014 Hi all,This is an open invitation for you to suggest new ideas and thoughts for Unilogic UDFB's.It is very important for us to keep track of our customers needs. As part of this agenda we want to create and develop useful tools for your benefit.These UDFB's will be attached to the next releases of Unilogic.Please feel free to suggest any idea that seems useful.Thank you Quote Link to comment Share on other sites More sharing options...

YINGD Posted November 16, 2014 Report Share Posted November 16, 2014 I'm not sure if this is the sort of suggestion you are looking for on this subject but I'll put it here anyhow. I think it would be great to have some statistical calculation functions. If there was the ability to read a vector/array of values and determine the statistical profile, that would be excellent! The values that would be most helpful I think would be those that are available in Excel when using the statistical analysis tools such are seen here (http://www.real-statistics.com/descriptive-statistics/descriptive-statistics-tools/ ) Quote Link to comment Share on other sites More sharing options...

I assembled it according to the "Descriptive Statistics" feature in Microsoft Excel. You may find it useful. Statistics_04_12.ulpr Quote Link to comment Share on other sites More sharing options...

YINGD Posted January 9, 2015 Report Share Posted January 9, 2015 Eyal, I was testing the Statistics program you made and I found a bug that I can't seem to figure out. The Max Value function seems to work fine but when the Minimum Value is less than 0, it sometimes rounds to 0. I tries to narrow down the symptoms and it is somewhat inconsistent. for example: - When I set the range to 2 and I put a 0.1 on the first register and a 5 in the second register, it works but if I reverse the positions so that the 0.1 is in the second register, and 5 is in the first it does not work. - When I set the range to 2 and I put a 0.1 on the first register and a 5 in the second register like the previous example, it works but then if I change the range to 5, it does not work. Attached are a few pictures to show what is happening. Quote Link to comment Share on other sites More sharing options...

Using your reference I found out that there is a bug in the "Sort Array" function block (which is used to determine min/max values in the application) - apparently It does not sort certain values. I referred it to our R&D department and this bug will be fixed in the upcoming Unilogic version. Thanks again for bringing this up. Quote Link to comment Share on other sites More sharing options...

Hi Y.INDS, FYI, the bug in Sort Array function block is fixed, and will be included in the next release of Unilogic (which should be available next month).

YINGD Posted September 10, 2020 Report Share Posted September 10, 2020 It would be great to have a filtering Algorithm such as the Stavitzsky-Golay Smoothing method shown here. https://www.mathworks.com/help/curvefit/smoothing-data.html I have struggled with a product of ours to find a good way to smooth data before charting it to a Trend. My issue looks the same as this example but I cannot seem to get my math right in Unilogic to get this to work in a UDFB. I think that even if I could get it into a UDFB, I find that sometimes a UDFB of this level of complexity would be better off as a Fixed Function Block rather than a User Defined Function Block simply because it would be cleaner and less likely to muddy up an already complicated program. I think that many other users could benefit from this as well. Thanks, Joe Quote Link to comment Share on other sites More sharing options...
zed Posted May 26, 2021 Report Share Posted May 26, 2021 Perhaps a little simple but how about a rate indicator like pcs/min or an hour meter like machine run hours. Quote Link to comment Share on other sites More sharing options...
TomButlerandLand Posted February 15, 2022 Report Share Posted February 15, 2022 A simple to use and understand 4-20 in/ 4-20 out Pid block like this HC900 example below would be very helpful. https://www.industrialcontrolsonline.com/sites/default/files/pdf/hw/HC900/HC900_SOFTWARE_SPEC.pdf BR, Tom Quote Link to comment Share on other sites More sharing options...

Yep! Kalman filters! and Point-in-Polygon! Quote Link to comment Share on other sites More sharing options...
RickL Posted October 22, 2023 Report Share Posted October 22, 2023 ………. and an “Indexed” Sort would be awesome!! : ) Quote Link to comment Share on other sites More sharing options...
