Exporting tags in a desired format (separator and column order)

Ewon Support
#1

Hi hms,

A client of mine is currently using 2 differents ewon :

  • An ewon Cosy with this firmware : EW_8_0s2
  • AN ewon Flexy with this firmware : 14…0s0PR

This client is retrieving the var_lst.txt file. The cosy file is comma separated and contains 59 columns. The flexy file is semi-colon separeted and contains 63 columns and the order of somes columns that exist within the cosy file have been reordered in the flexy file.

My client was wondering :

  1. If it was possible to change the separator from semi-colon to comma in the flexy file.
  2. If the column could be in the same order

To be noted, I’m aware that the flexy is using a pre-released version of the firmware. I’m not the person who configured it and I’m more than willing to updating it back to a released version if necessary.

Thank you for your time and your help,

Hi @ktmachinex

The easiest way to do this would just be to take the var_lst.txt file and do a control f to search for commas and then just do a replace all with a semicolon. But I’m confused about how you’re getting tags on a Cosy. The Cosy does have a var_lst file, but you don’t have a way to setup/interact with tags on a Cosy. The Flexy reads the Var_lst as a semicolon delimited file and won’t read it as a comma separated file.

The order of the Var_lst file has changed a few times with each new addition in firmware, so the order of two var_lst files from different firmwares will likely not be the same.

But I’m confused about how you’re getting tags on a Cosy.
I just verify on the Cosy and you can go to Configuration\Tag Setup and click on create new tag link. So there is definitively a way to configure tags in a Cosy.

As I understand from your answer, there is no built-in ways to achieve what I’m asking without doing manual manipulation. Is that correct?

I was looking for a way to do it within the ewon config and parameters without having to program anything (creating an app or a script as I’m a programmer).

The order of the Var_lst file has changed a few times with each new addition in firmware, so the order of two var_lst files from different firmwares will likely not be the same.

Are these changes listed in any documentation? That would be helpful.

Thanks again for your help,

Hi @ktmachinex,

You may be able to store tags on a cosy, but you won’t be able to do anything with them. A Cosy is just for remote connection to devices but a Flexy can be used for remote data.

Unfortunately the Flexy is only programmed to read a semicolon delimited var_lst file.

As for the changes between firmwares, these are listed here:

While it doesn’t necessarily happen each time there’s an update, when something like the addition of string tags. It will add an additional column that modifies the way the var_lst is organized.
