Post by rckalex on Changing Trace Variable at Runtime ^{CODESYS Forge talk (Post)}
Is it possible to change the variable being traced during runtime? I would like to use the CURRENTCLIENTID in combination with an array of real numbers to alter the traced variable in a display window, without needing to create separate visualizations for each variable.

Post by kuuki on Losing focus of variable ^{CODESYS Forge talk (Post)}
Hi. Does anyone know how to fix a problem with losing focus of a variable in FBD editor. Sometimes when trying to edit variable name, array index, etc. in network, editor randomly exits "text edit mode" and variable is replaced by text you were typing.

Post by peterkcontrols on Making a Visu Element normally invisible and visible if variable is true ^{CODESYS Forge talk (Post)}
Hello I would like an element in my visu to be only visible when a certain Variable is true, currently it is only capable of being normally visible and then invisible if a certain variable is true. Is this possible without programming a new variable to be the opposite of my desired control variable? Thanks.

Post by dogulas on numeric text box control ^{CODESYS Forge talk (Post)}
Ok, this is how I made a numeric text field: use a Text Field properties -> Texts -> Text := %f (or %d or whatever you need) properties -> Text variables -> Text variable := (your numeric variable) properties -> Input configuration -> OnMouseDown -> Configure: Write Variable Input type := VisuDialogs.Numpad Use another variable (your numeric variable) Min val Max val etc. Please tell me there is an easier way to do this.

Post by timvh on Stack overflow with really simple function ^{CODESYS Forge talk (Post)}
You have declared the function block in a function and call the instance also from a function. This is not correct, because a function is initialised with every call. The http client function block should be declared as Global Variable if you want to cal it from a Function, but probably it is better to declare it in a Program and also call the instance of the http function block from the same Program.... The variables of a Program are not initialised with each call.

Post by rodberna on Library for arrays ^{CODESYS Forge talk (Post)}
Hi, I'm creating a program where I need to handle arrays, like: - Declare lenght variable arrays - [array(1..var) of "sometype"]. This is not possible in pure codesys, right? - Know array lenght, min, max, avg values in runtime - append/delete itens in an array - and so on Is there a library know for this in codesys. Is it possible to build our own libraries using some high level language like python or java script?

Post by ojz0r on INT_TO_WORD function not working ^{CODESYS Forge talk (Post)}
That calculation will not work the way you expect it to. If PumpFillSpeed is limitied to 0-50 then the only whole number would be 50/50 = 1 everything else is 0.0-0.9999... and since you are using word and integer only 50 would work since there is no representation for mantissa in integer values. Declare a temporary real variable and do the calculation and then do a REAL_TO_WORD in the DRV2Speed assignment.

Post by carohe on %t SystemTime in Variable ^{CODESYS Forge talk (Post)}
Hello, if you enter %t as a "Text" on a rectangle and do not link a variable in "Text variable", it automatically displays the system time. My question is, where do if find a variable, that contains exactly this time? I tried numerous variants using GetLocalDateTime or GetSysTime but I always have to manage timezones myself (which I do not want to do). I only want a variable with the date an time from my windows system, where the visualization is running. Where can I find this variable?

Post by bmatlove on Variable Length Array - Cannot mix variable and fixed length dimensions? ^{CODESYS Forge talk (Post)}
Using Codesys 3.5.18.30 I am trying to work with an array of variable length in one dimension, but known in the other dimension. For example, using an array that represents a list of items, each with an attribute profile. I do not know how many items will be in the list, but I know that every item has 5 attributes, like size, weight, etc. Codesys does not seem to be able to accept this. I have referenced Data Type: ARRAY OF documentation page, which is not explicit if variable & fixed length array dimensions can be mixed. In the VAR_IN_OUT scope, I initially tried MY_ARRAY : ARRAY [*, *] OF REAL; which was no problem, of course. I then modified it to MY_ARRAY : ARRAY [*, 1..5] OF REAL; which throws C0006: ', or ]' expected instead of '..' among consequent downstream errors. I then used the Auto Declare -> Array Wizard, which accepted (asterisk)-(asterisk) and 1-5 for 2-dimensional lower and upper bounds. It output: MY_ARRAY: ARRAY[*..*, 1..6] OF INT; which throws the same error stream. What's the deal here? Is this possible?
