Post by niloufar on Execution Order of Function Blocks ^{CODESYS Forge talk (Post)}
Hi, Our program incorporates various function blocks and programs written in different languages such as St and SFC. They implement numerous actions and methods using different languages from their function blocks. My question is whether the execution order of function blocks is associated with the programming languages used. I understand that cycle time can be configured in the task configuration, but I'm curious if there is a specific sequence order of execution for function blocks written in different languages. For example, all function blocks in (ST) are executed first, followed by the execution of (SFC). Specifically, when the function is written in (ST) and the action is implemented in (SFC). I modified all function blocks in the main PLC program and configured a task configuration for the main program.

Post by winki on Modbus TCP Client ^{CODESYS Forge talk (Post)}
Hello, I am new on CODESYS env. I would like to do some Modbus TCP, but I am wondering If using codesys you must use the device "Modbus_TCP_Client" & "Modbus_TCP_Server". I would like to do it without device, only using ST. Is that possible ? I try the example : MODBUS_master_example, but it is not working. If it is possible to dot it without any Device I will show my code. Thx a lot

Post by matthew on New Ladder Diagram conversion does not work due to missing features ^{CODESYS Forge talk (Post)}
Hi @eschwellinger Just wondering if there is any update when the Expression or part of it has no effect will be fixed? Also have the ability to open an FB when online and offline. It would also be great to be able to view the ST code block when online.

Post by davidmic on What is this ST syntax? ^{CODESYS Forge talk (Post)}
I found some structured text code which contained this statement: bHidden:= TRUE(*NOT _somevariable*) I haven't seen TRUE() used like a function before, and I also haven't seen the enclosing asterisks * * before. What do they do? (sorry if this is a duplicate question, I don't know what words to use to search for this syntax)

Hello! I am interested in the Modbus Slave channel parameter uiReadLength to use in the ST-program (see picture). How to read the value of uiReadLength in a ST-program? Only Edwin the Great and Terrible can answer this question.

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');

I think what you want is a declaration period function for the page, but unfortunately CODESYS does not have it.
