okay but will this pass the array by copying it or it will be a reference to original array only.

Hey, Sorry this isn't super helpful, but i had this problem once and was able to resolve it. I can't recall how I solved it and whether it was a problem with my codesys installation or the project itself. If it is the codesys installation, make sure all your required libraries and plugins are installed and available. compare with a colleagues installation if possible. I vaguely recall saving a copy of my project and deleting things one by one until the error went away...

I have been trying to set an array value to a JSON structure of this form: {"key": [1,2,3,4]} While I have been able to create the key and set its value to an empty array, I've not had any luck in putting any value in that array. objindex:= fb_JBuilder.SetKeyWithArray("Key6", diParentIndex := diRootIndex); objindex2:= fb_JBuilder.SetValue(value:= iValue2, diParentIndex:= objindex); iValue2: ARRAY[0..3] OF INT:= [1,2,3,4]; The two lines of code above produce {"key6": []} . The second line essentially has no effect.

Hi everyone, Had that problem before where I could not create another user but used the method just above and it worked great. My problem now is that I get this message when attempting to logon to the device: invalid user authentication on the target dev5, the new user created is pretty much a copy of the user 'Owner' except for the password. Any idea as to why I am always getting this "invalid user authetication on the target" message ? Using Codesys V3.5 SP19 Patch 6 + (64 bit) Regards

It will be a reference, because it's a VAR_IN_OUT. it's a little weird debugging the array online. It just shows as a POINTER TO INT, and you can't actually see the array from the function side. But you can still work with it as a normal array, not a pointer.

on a raspberry pi delete the folder and its content before licensing. /var/opt/codesys/cmactlicense If you plug this SD card in another raspi ( which has another hw-serial number) you'll get a second empty softcontainer. This could lead to an unlicensed PFC (it could only handle one container) The solution is: To delete the /var/opt/codesys/cmactlicense directory and content of it and then aktivate the lizenz via WibuCmRau file and Lizenzmanager.

(Post)
Updated the Codesys Safety SIL2 package from v3.5.18.1 to v3.5.22.10 Codesys Version 64 3.5.18.0 After the update the assignment of variables from different VarGlobal lists was unstable. Selecting one group could cause another group to be deselected after code generation. I was unable to perform a compilation were all variables maintained the selection after code generation. Rolled back to the older version and the issue seem to be mostly solved.

To search for an exact phrase, put it in quotes. Example: "getting started docs"
To exclude a word or phrase, put a dash in front of it. Example: docs -help
To search on specific fields, use these field names instead of a general text search. You can group with AND or OR.
