Post by manuknecht on Opening a Dialog on a specific Client from ST ^{CODESYS Forge talk (Post)}
I managed to find a solution that seems to work reliably. As the VU.Globals.CurrentClient-filter accesses the CURRENTCLIENTID or at least a similar, internal variable it can only be used if called from a certain client (e.g. from a button in a visualization). My solution works by implementing a new client filter that compares the client ID of all clients to the ID of the last client that was used. The variable containing the data of the last client is defined as: G_LastClient : VU.IVisualizationClient; // Copy of last client that detected click This last client is then updated every time a button is pressed using the Execute ST-Code input configuration of the button: G_LastClient := VU.PublicVariables.Clients.Current; Next, I created a function block that implements the client filter interface as so: FUNCTION_BLOCK FB_LastClientFilter IMPLEMENTS VU.IVisualizationClientFilter VAR_INPUT END_VAR VAR_OUTPUT END_VAR VAR END_VAR Then i added a method to the FB called IsAccepted which is used to filter out the client. When creating the method, it should automatically be filled with the according variable declaration, as it is defined in the interface: (* For every client can be desided, if it is accepted. ``TRUE``: Client is accepted*) METHOD IsAccepted : BOOL VAR_INPUT (* The client, to check*) itfClient : VU.IVisualizationClient; END_VAR Now the client can be compared to the last used client as such: // check if clientID corresponds to clientID of last recorderd client IF itfCLient.ClientId = G_LastClient.ClientId THEN IsAccepted := TRUE; ELSE IsAccepted := FALSE; END_IF To make use of this custom client filter, initialize a variable with the client filter: LastClient : FB_LastClientFilter; // Client filter to find last used client Then use this client filter when opening or closing a dialog from ST: fbOpenMyDialog(itfClientFilter:=LastClient,xExecute:=TRUE,sDialogName:='VIS_MyDialog_DLG');

Post by manuknecht on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
Thanks for your responses. The close listener sounds like an interesting approach, will have to see what I can do with it. I actually solved it as suggested by sturmghost by setting an enum variable to a certain state as soon as I open a dialog. This way I always know which dialog was opened last.

Post by leon78 on Codesys 3.5 SP17 Patch 2 CheckBounds (POUs for Implicit Checks) ^{CODESYS Forge talk (Post)}
Hello! I use CheckBounds (POUs for Implicit Checks). But I have a problem. I use an array as an VAR_IN_OUT of Function Block. If I try to monitor the array of variable length ([* ]), its does't work. The CheckBounds POU isn't called. If I use the array of fixed lenght ([lower..upper]), the CheckBounds POU is called. Why?

Post by ewi04 on Recipe Manager - RecipeManCommands, load & write wrong values, Bug? ^{CODESYS Forge talk (Post)}
The individual structures were declared in a separate global variable list on a trial basis. But even this did not change the behavior. A total of 1667 variables are processed in a recipe. A reduction (e.g. saving only the first three drive parameter sets) also brought no change.

Ich würde gerne bestimmt Modbus RTU Slave Adressen auslesen, leider bekomme ich keine Werte vom Bus. Verbindung erfolgt über einen Raspberry mit Modbus RS485 Adapter, welcher erfolgreich verbunden ist. Mit einem IOBroker kann ich die Daten erfolgreich auslesen. In der Modbus_COM_Port => Modbus_Serial_Device habe ich Input Register 4000 %QW und Startadressen auf Input Register 3000, als Variable ein Array[0..2999] of Word, kann aber keine Werte auslesen.

Post by scarter on Bit / Bool data types in function parameters ^{CODESYS Forge talk (Post)}
Any reason BIT and BOOL data types are not interchangeable? Trying to make a function which takes a BOOL IN/OUT parameter (Not allowed to use BIT) In the main logic if I make a DINT variable, and want to use each bit on different functions CODESYS will not allow it.

Post by gurkan on OPCUA array max length? ^{CODESYS Forge talk (Post)}
We are using codesys 3.5.16.30 and we have a array with strings of length 5000. We are having issues subscribing to this variable from an OPCUA client. Is there any limit in the OPCUA Server in codesys for how long an array can be on the opcua server?

Post by evanclegg on Digital Clock ^{CODESYS Forge talk (Post)}
To display the current time, you’ll need to retrieve it from the system clock. In CODESYS, you can use the built-in function SysTime to get the current system time. Here’s an example of how you can use it: VAR dtCurrentTime: DATE_AND_TIME; sTime: STRING(8); END_VAR dtCurrentTime := SysTime(); sTime := TIME_TO_STRING(dtCurrentTime.t); The sTime variable now contains the current time in the format “HH:MM:SSuno online".

Post by struccc on Release SP20 - Changes in behaviour? ^{CODESYS Forge talk (Post)}
Wow.... I missed this one in the manual - so there is a special syntax to invalidate a reference... Great :) Seems to work. (it's just mentionned in the examples line)... I've always assigned 0 to the variable, with := 0 - like setting a pointer to 0. In theory, that should work as well. Thanks!

I'd like to measure tool length using SW. How do I set variable from the accurate drive position when switch turn ON/OFF? Hopefully, I'd like to measure Z-Pos with M-Function in G-Code automatically, And I'd like to set it to G43 as tool length correction.

Could this be turned into a library? I'd love for a way to have the main program call a function block method using the program's I2C_master device. I assume I should be passing the master as a variable for the function block, but I don't see how that could be achieved

have a look at UNIONs. With a union you are able to write single bytes to the same adress area which belongs to a float variable at the same time. I like to do a lot of convertions belonging to interfaces and fieldbus in this way, f.eg. word / byte swapping etc.

Hi everyone, I am facing issues with persistent retain variables. It was working fine. I added a few new Persistent variables and it stopped working. If I do cold reset it holds persistent variable values. But when I close control win gracefully, and opens it again then it does not. Even, it is not saving ret file in application.
