The whole OPC UA package is now in .net standard - can some one share any articles on how to build a .nar file from the open source GIT repo ? ... View more

Any updates to this one, Matt ?  ... View more

Attached ny sample template.    1. I get the OPC UA protocol data from the industrial machines - in my case currently, it is a simulation server called prosys.  2. Once the stream is setup - for every second - I am interested in one counter's value and am configuring the nodelist for the same to be pulled.  3. I split out the values and end up with value list which contains counter vd value and timestamp.  4. I need to aggregate 20 -30 of these records - i am using mergecontent for the same  5. Now i will need to calculate the time difference between each of those records and figure out cycle time that has elapsed between first and second record, second and third etc.... only if the time stamps are different.        <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <template encoding-version="1.2"> <description></description>

Thank you Matt. Yes, the content of the flowfile contains the time stamps. But this is after merge content and not before. Let me send a sample tomorrow of what I intend to do so that you could help me out. ... View more

Thanks for the response Matt.    I recieve a continuous stream from one of the machines.  Let's say the timestamp of 1 flowfile is 10 am  And the next is 10 02 am, 10 05 am etc..  I am merging 20 such records using the merge content processor and getting a json response as a single flow file.   Now I need to write a loop to check for the number of records and compare the timestamps vs the previous timestamp and calculate it took 2 mins for first iteration. .. ur. 10 to 10 02. Then 3 mins for next. Etc.  The idea is to calculate cycle time between the first flow file and the next flow file content. Since only one flow file is generated I have to merge contents of the flow file before this.    Let me know if there is a better way to handle this scenario.  ... View more
