Data Logging

[Ataxie]

Hello,

 

I am looking for a way to record the events occurring in the program, for example:

Employee X changes the position of the height of the robot.

 

Desired result: Timestamp; Variable; Current value Previous value; User

 

In order to export it to a csv file by ftp / mqtt / db / ... (this point is OK)

 

I have at disposal:

an NJ501-1320

an NA5-15w101s

 

The problem would be how to treat a structure that can contain x variable of undefined type, which can also be substructure.

(Recipe.robot1.position [3] .z)

 

I had imagined to transfer the structure in 2 array in order to compare them, and to highlight the data having been modified, except that I did not find adequate solutions.

I also did not discover how to get the name of a variable from a structure, and save it in a string

 

have I been clear enough?

(the only actual way i've found to do so is to get the data by opc and founding something that can do it that way)

 

Thank you for your help

Since you have no idea what data type the variable is going to be, you're really limited.  My recommendation would be to turn all the data into strings and add those strings together, then save that into an array of strings.

I'd already thought about that but a probleme was still there ... how can i manage to get the variable name and not only the value.

I've finally found a solution, using the OPC-DA protocole and KepServerEx. After that, exporting all the data on a SQL server.

 

But thanks for your reply

we can delete or close this if nobody want to fill more info
