Hi, there is a plethora of hardware available for it to be succesful on. In theory every ARM32/64 or x86/64 device is a potential target. Next to this there are embedded device platforms for which specific toolchains are available. A good starting for manufactureres of CODESYS capable devices is available here: https://www.codesys.com/the-system/codesys-inside.html. That should give you a good reference point.

Post by pistola on C0357: "GetNextClient" is obsolete, use VisuUtils instead

I'm having some troubles with this same issue and I'm wondering if someone can help me out. On a settings visual I allow the operator to enter some values however if they activate the page change button it will change the change with the Numpad dialog open. Since I'm using Visuelems.CURRENTVISU to change the pages I came across this code noted below for determining if the Numpad dialog was active. This code worked great however now in 3.5.19 it's now obsolete. I've tried following the directions in the attached program above however I can't see to get it to work in my program. Can anyone provide some help to determine if a dialog is open? FUNCTION Check_Dialog_Open : Bool VAR_INPUT sDialogName : STRING; // Input variable for the name of the dialog END_VAR VAR pstClientData : POINTER TO VisuElems.VisuStructClientData; // Pointer to the client data structure itfDialogManager : VisuElems.IDialogManager; // Interface for the dialog manager itfMyDialog : VisuElems.IVisualisationDialog; // Interface for the specific visualisation dialog END_VAR // Begin the iteration over the client manager VisuElems.g_ClientManager.BeginIteration(); // Loop through each client until no more clients are found WHILE (pstClientData := VisuElems.VisuElemBase.g_ClientManager.GetNextClient()) <> 0 DO // Get the dialog manager interface itfDialogManager := VisuElems.g_VisuManager.GetDialogManager(); // Get the specific dialog interface using the dialog name itfMyDialog := itfDialogManager.GetDialog(sDialogName); // Check if the dialog is open for the current client Check_Dialog_Open := VisuDialogs.VisuDlgUtil_IsDialogOpen(itfMyDialog, pstClientData, itfDialogManager); // If the dialog is open, exit the loop IF Check_Dialog_Open THEN EXIT; END_IF END_WHILE

I had the FB called via a for loop to call a few instances of my FB I have removed it the for loop and just called them 1 by 1. Seems to have sorted the problem. tho, i have other FB's and for loops doing the same thing but they are all fine. below is basically what was happening. var: mVibrator : ARRAY[1..GVL_Settings.Number_Of_Products] OF Main_Vibrator; end_var Controller(PRG) call: FOR v := 1 TO GVL_Settings.Number_Of_Products BY 1 DO; mVibrator[v] (); END_FOR So at state 30: the mVibrator[1].start was turning on 30: Main_Mixer.Start := TRUE; Process_State := 2; IF Main_mixer.Done THEN Main_Mixer.Start := FALSE; Control_State := 40; END_IF but its not till state 50: that it is actual in the code. 50: Main_Suction_valve.Open_Input := TRUE; mVibrator[1].Start := TRUE; Process_State := 4; IF GVL_Weigh_hopper.LoadCell_Weight = 0 THEN Main_Suction_valve.Open_Input := FALSE; mVibrator1.Start := FALSE; Control_State := 60; END_IF Thanks for your input.

Hi mate, With this snippet i was able to see the lastusage variable count, but it would not iterate between clients? i was only able to access the data of the target visu. it threw an error with the array of pointers stating it was not able to convert etc. also when i tried it with the while loop it created an endless loop and crashed the program. any ideas? Thankyou

CODESYS Forge

OK.. so maybe I miss understood for how the forcing order works. It seems that the force list is applied at the beginning of every task call (I'm assuming this based on what I am seeing). If I force my variable FALSE and then write it TRUE in a task, then it stays TRUE for that task, but then in the next task it will go back to FALSE.

Post by rmaas on Strange Behavior on Raspberry Pi
CODESYS Forge
talk
(Post)
Hello, what you are seeing is not strange behavior. The problem is that everyting is happening in the same program cycle. After the variable Stepnumber is changed from 10 to 20 for example then you want the program to wait with the next EQ until the next program cycle. Else every EQ will be be true because in every line the variable Stepnumber is increased. When the program arrives (still in the same cycle) at the line with the timer, the Stepnumber has been increased to 30 in the meantime and the timer will allway be ON because even though the variable is written to 10 in this line in the next cycle it starts with 10 and will be 30 again before reaching the timer in line 8. Not very good at explaining stuff but i hope you get the problem. See screenshot below for an example of one way you could solve this...

Post by farren on How to stay in a method until something is finished.
CODESYS Forge

I know I'm thinking about this wrong -- too many decades of procedural and event-driven programming and only a few months of PLC ST programming...... I've created a visualization with a button that when pushed calls a method. I want the method to take a pressure reading, wait one minute and then take another pressure reading. I'm looking for leaks. I'm using TON for the delay. It seems like what is happening is that the method gets called once and it takes the first reading and starts the TON. But then execution continues, leaves that method call, and the second reading never happens. I can force the method to keep running until the whole thing is done with a While loop, but I understand that is considered BAD in PLC programming. If it push the button again to call the method again, it picks up where it left off and if the timer is complete then it runs the remaining code. How do I keep that method running until it is complete with just one call without using a while loop that ties up the PLC for a minute? Thanks! -Farren

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.
