Is there a way to reset the MeasurementIndex of a CANoe Simulation to 0?
I'm currently working on a myCANoe.cfg simulation that was saved multiple times. I'm creating log files with the structure myCANoe_{MeasurementIndex}.blf and MeasurementIndex = 800 right now. I'd like to tweak the text in myCANoe.cfg to reset it to zero. So far, searching for the string was not effective, nor it was changing the preview text myCANoe_800.blf in myCANoe.cfg. Can we achive this result somehow?
Turns out there is a simple way. Please be sure to have a back-up plan in case the following edits go south. You'll need to manually edit the myCANoe.cfg file, possibly resulting in complete corruption of the simulation. I was able to achieve the result with the following:
Note the current measurement index (e.g. 800)
Delete myCANoe.stcfg compiled file
Open the simulation
Check current measurement index again and close simulation
Delete myCANoe.stcfg again
edit myCANoe.cfg with a text editor
Search for the measurement index value (800). I found two results: one on row 609, one with the format <VFileName V7 QL> 1 "myCANoe_800.blf"
Edit both to 0 and 000, respectively. Save
Open the CANoe configuration, My measurement index was re-set.

I am part of tractor pulling team and we have Bechoff CX8190 based PLC for data logging. System works most of the time but every now and then saving sensor values (every 10ms is collected) to CSV fails (mostly in middle of csv row). Guy who build the code is new with the TwinCAT and does not know how to find what causes that. Any Ideas where to look reason for this.
Writing to a file is always a asynchron action in TwinCAT. That is to say this is no realtime action and it is not safe that the writing process is done within the task cycletime of 10ms. Therefore these functionblocks always have a BUSY-output which has to be evaluated and the functionblock has to be called successivly until the BUSY-output returns to FALSE. Only then a new write command can be executed.
I normally tackle this task with a two-side-buffer algorithm. Lets say the buffer-array has 2x100 entries. So fill up the first 100 entries with sample values. Then write them all together with one command to the file. When its done, clean the buffer. In the meanwhile the other half of the buffer can be filled with sample values. If second side is full, write them all together to the file ... and so on. So you have more time for the filesystem access (in the example above 100x10ms=1s) as the 10ms task cycletime.
But this is just a suggestion out of my experience. I agree with the others, some code could really help.
Sometime when edit large files like more than 100GB. (my pc physical memory is 128GB and using nvme ssd)
small change . vs fast save ?
when i did a small change on the file, like deleting the first line of a file. Is there a more efficient way to complete this function ?
200gb file takes half a hour to save.
Sometime emeditor will detect json or csv error rows. Is it easy to mark these rows as bookbooks? So it will be easy to extract or delete these lines.
Can sequence number auto-fulling used in replace ?
When edit more than 100M rows. As I know,
the normal function should be
switch into csv mode and
insert a new column. and
then filled with sequence numbers. these steps also time-consuming.
These step can be fullfilled by replace function? an example bellow.
example:
{"Genres":"Drama","Product":"Ice Cream - Super Sandwich","Title":"White Lightnin'"}
{"Genres":"Drama|War","Product":"Raspberries - Frozen","Title":"Leopard, The (Gattopardo, Il)"}
{"Genres":"Crime|Drama|Film-Noir","Product":"Cookie Dough - Chunky","Title":"Limits of Control, The"}
{"Genres":"Drama|Mystery","Product":"Watercress","Title":"Echoes from the Dead (Skumtimmen)"}
{"Genres":"Drama|Thriller","Product":"Cumin - Whole","Title":"Good People"}
need to convert into
{"id":1,"Genres":"Drama","Product":"Ice Cream - Super Sandwich","Title":"White Lightnin'"}
{"id":2,"Genres":"Drama|War","Product":"Raspberries - Frozen","Title":"Leopard, The (Gattopardo, Il)"}
{"id":3,"Genres":"Crime|Drama|Film-Noir","Product":"Cookie Dough - Chunky","Title":"Limits of Control, The"}
{"id":4,"Genres":"Drama|Mystery","Product":"Watercress","Title":"Echoes from the Dead (Skumtimmen)"}
{"id":5,"Genres":"Drama|Thriller","Product":"Cumin - Whole","Title":"Good People"}

I am converting an SDK vi provided by a data acquisition card company to suit my needs. The original vi records multiple data segments in the card memory and displays in a waveform graph on the front panel without any saving to file function. I can input "Number of Records" to set how many segments (waveforms) I want to acquire. Once the acquisition is over, I can click on "segment" (a "control" on the front panel to input a number) to view the nth segment. To save all the data segments into one file, I put the "Write Delimited Spreadsheet VI" in this VI, with attache to file and transpose function.
My problem is that once I add the save file function, the VI is only saving one segment if the "Run" is set at "False," and then by clicking the arrow to add one in the "Segment" control on the front panel, the next segment data will be saved in the same file and attach after the previously segment. Or the VI will keep saving data without stopping if the "Run" is set at "True. What I want is when I set the "Number of Records" as X (an integer), the file will save X segments. I tried to add a counter to automatically add one each time and replace the "Segment" input but was not working.
I feel that I am getting very close to what I want but after a week I decided to ask for help. Any comments and suggestions welcome. Thank you.
A counter is needed. Add it to shift register of the While Loop (not the For Loop!).
Add saving of data to the While Loop (move it out from For Loop).
Increase counter (in the While Loop), and save data until the counter reaches Segment’s value.
Let me also give one recommendation: try to change current implementation to some more flexible design pattern (such as State Machine or Producer-Consumer). Currently, your code is quite messy, coupled, etc. - so it could be a challenge to debug it or to add new features. Both of the patterns mentioned can be explored more by looking at the Project Templates (available when you create a new project).
I'm trying to automate some set of test cases which would pass inputs from one to another. For instance, if I have 5 test cases then 1st test case would pass input to 2nd - 2nd to 3rd - likewise it goes on.
And another point to be noted is that I won't perform batch execution and there will be a certain time gap between each test case.
So what I'm trying to do is like updating the outputs into some excel sheet and call them during succeeding execution. I have tried searching and tried some codes, but nothing has worked out.
So please share some idea to update excel sheet during run time which is placed in QC. Thanks!
What you're essentially saying is that you have test runs separated by some indeterminate amount of time, and you need to share data between runs. The answer is you need persisted storage of your data. You could use a database, flat file, Excel spreadsheet, or anything else that will let you programmatically write data in one run then read it in the next.
Excel spreadsheets are one such solution. You said you tried it and it did not work. That likely means that the method you used to write or read the data was incorrect, and not that there was a problem with the concept. If you provide some more specifics about exactly what you tried and where it failed, hopefully the community will be able to assist you.
I Believe you have Input Excel Sheet(s) in QC, What you can do is download the excel file from QC to local machine, store output from 1st test case to this excel sheet and upload back to QC. Which now you can use as input to next test case.
I am using JMeter and have 2 questions (I have read the FAQ + Wiki etc):
I use the Graph Results listener. It seems to have a fixed span, e.g. 2 hours (just guessing - this is not indicated anywhere AFAIK), after which it wraps around and starts drawing on same canvas from the left again. Hence after a long weekend run it only shows the results of last 2 hours. Can I configure that span or other properties (beyond the check boxes I see on the Graph Results listener itself)?
Can I save the results of a run and later open them? I know I can save the test plan or parts of it. I am unclear if I can save separately just the test results data, and later open them and perform comparisons etc. And furthermore can I open them with different listeners even if they weren't part of original test (i.e. I think of the test as accumulating data, and later on I want to view and interpret the data using different "viewers").
Thanks,

Don't know about 1. Regarding 2: listeners typically have a configuration field for "Write All Data to a File", which lets you specify the file name. You can use the Simple Data Writer to store results efficiently for later analysis.
You can load results from a previous test into a visualizer by choosing "Write All Data to a File" and browsing for the file you wish to load. Somewhat counterintuitively, selecting a file for writing also loads that file into the visualizer and displays the results. Just make sure you don't run the test again while that file is selected, otherwise you will lose your saved test data. :-)
Well, I later found a JMeter group that was discussing the issue raised in my first question, and B.Ramann gave me an excellent suggestion to use instead a better graph found here.
