Post by peterned on Array to String ^{CODESYS Forge talk (Post)}
max. string length in Codesys is 255 chars. It's not possible to cram 20,000 things in a string. If you need to send the data to another device, send the whole data[] array (as byte array, without doing anything to it) and extract the information on the other end. As each struct member has a fixed size (81 bytes, as per you declaration), this will be easy. To save some resources, consider declaring string lengths - e.g. if the max possible length for key is 10 chars, declare it key: STRING(10); and it will occupy 11 bytes instead of 81

The string_Util_Intern is not the library I referred to. With a CONCAT function (also with the string util library) a search is done for the NULL character. If you concatenate 20000 characters to one string, then the longer the string, the longer it takes to find this NULL character.

Hello @florian, Could you please help with how to set an array value? I've been trying to use the with the setKeyWithArray method which creates the key with an empty array value. But I have been unable to set items in this array? objindex:= fb_JBuilder.SetKeyWithArray("Key6", diParentIndex := diRootIndex); objindex2:= fb_JBuilder.SetValue(value:= iValue2, diParentIndex:= objindexx); //iValue: array[0..n] of int; Best regards

It seems that there is a limitation with the STRUCTs. Does anybody know, what’s okay to save (add to the recipe) and what’s not okay? Or is there another problem with my project? If I have only an array in the recipe definition everything works perfectly (see project).

Post by tehthoams on Find Function: Object reference not set to an instance of an object. ^{CODESYS Forge talk (Post)}
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...

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

Post by corriibme on Setting array values with JSON Utilities SL ^{CODESYS Forge talk (Post)}
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.

Post by mp9876 on Device User Logon ^{CODESYS Forge talk (Post)}
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

Post by tvm on Cannot pass array of constant size to a function as a reference ^{CODESYS Forge talk (Post)}
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.
