Post by trusty-squire on Strange problem with the ‘MC_SetPosition’ function ^{CODESYS Forge talk (Post)}
Here, it seems to me that we are getting completely off track with the observed problem. If questions clarifying the details of the installation are problematic, it's best to include those details in the original question then... I had already written this elsewhere. The program before being brought into machines was exhaustively tested in SW emulation and the problem did not occur. Testing the full program in emulation is entirely different from creating a simplified program to isolate the function causing problems in the real world. I would recommend trying it to isolate the issue. The drive and motor have been working fine for about 10 years. In replacing the machine control system, I opted for CoDeSys where before there was something else. But this is not the subject of the problem A simple "yes" is the correct answer to my question here... Anyways, you seem to be a very knowledgeable expert, good luck on your problem!

Post by dtamm on How to read string from CharBufferPtr? ^{CODESYS Forge talk (Post)}
I am trying to implement a mechanism to send alarm SMS. For this, I have created an Alarm Class with a Notification Action which calls a POU. This POU implements IAlarmNotifiable making it selectable in the Alarm Class configuration. IAlarmNotifiable has an Execute method which is called by the alarm class. Now, I want to extract the alarm message of the triggered alarm. The Execute method comes with a VAR_INPUT itfAlarm: AlarmManager.IAlarm which supplies a method called GetMessage. The help text says: Returns the message text, that has been configured for the alarm. The result is a pointer to the buffer, where the message text is stored The type of the result is CharBufferPtr, and at some place I read that it can be interpreted as a pointer to string. But I cannot manage to extract the alarm message, all I get are numbers. I have tried the following: psAlarmText := itfAlarm.GetMessage(__SYSTEM.TYPE_CLASS.TYPE_STRING)^; sAlarmText := TO_STRING( itfAlarm.GetMessage(__SYSTEM.TYPE_CLASS.TYPE_STRING)^ ); So how do I get access to the alarm message as clear text? (In this case, "Larm 1")

Post by william-blandon on RecipeManCommands.ReloadRecipes ^{CODESYS Forge talk (Post)}
Hi Dave. Thanks for your answer. I still struggling with this. I have done everything according with the Codesys help even I have looked in detail at the example. I have double checked the recipe manager configuration and the use of all the methods. There are two methods that do not work as expected. I'm using Codesys 3.5.19.20 and recipe management 4.4.0.0 .CreateRecipe just create a recipe in the recipe definition but do not create the file. This have a walk around just giving a .ReadAndSaveRecipe afterwards. .ReloadRecipes do nothing but do not generate any error as well. After calling it I call the .GetRecipeCount and the number is always 0. When I create a new recipe (using the function block methods) then the number changes. Looks like this method is looking to the wrong directory finding nothing. I don't know if there is a missing configuration in the CODESYSControl.cfg file. I'm thinking in a walk around for this but I need to create a strings array with the recipe names as retentive and making all the management when deleting and adding recipes. Have had some one the same problem?

Post by alex-at-xana on EThercat Dynamic configuration ^{CODESYS Forge talk (Post)}
Hi Everyone, For a fast monitoring system I am using Ethercat oversampling and timestamping inputs. As the customers has a lot of different configurations out in the field, we went for a dynamic Ethercat configuration. Already got the whole detection chain working but now I am stuck since two days in debugging the configuration. Here are my quesitons: I extended the dynamic config example for the EL3632 16#0E303052: //EL3632 pSlave^.SetDCSettings(TRUE,TRUE,80,80,TRUE,4000,0,0); pSlave^.AddSyncManager(16#1000,128,16#26,TRUE,3); pSlave^.AddSyncManager(16#1080,128,16#22,TRUE,2); pSlave^.AddSyncManager(16#1100,0,16#4,TRUE,1); pSlave^.AddSyncManager(16#1110,214,16#20,TRUE,0); pSlave^.AddFMMU(0,214,0,7,16#1110,0,1,1); pSlave^.AddFMMU(0,1,0,0,16#80D,0,1,1); xKnown := TRUE; This leads to a PLL Error for these devices. I double and triple checked the configuraton, but cannot find the issue. There seems to be one difference: the config dialog creates a startup parameter: 16#10F3:16#05, Name: Command_0, Value:0. Bitlen: 16, Stop on fault: false, jumpt at fault: false: next line: 0 a) I do not find information on how to set this in my code. Can you help me there? b) Without trying to set the value, I get a PLL error for these devices in the master log. Is the config wrong? c) Do I need to set the Master to Autoconfigure or Manual? I used autoconfigure for my tests. The stack creates input data addresses for the slaves input data range (pSlaves[i].InputData) which are different from those created when I use the Engineering tools dialogs to configure Ethercat. Specifically, the addresses seem to be aligned at 16 byte boundaries when they are created using the engineering tool, but may appear at uneven addresses when I use the script in dynamic config. I did not try to access ULINT at uneven addresses yet, but I am suspecting this may be a problem. Do I need to manually align the addresses ? Any help is appreciated...

Post by aliazzz on Unable to deploy Virtual Control SL on ARM64 (Raspberry Pi5) ^{CODESYS Forge talk (Post)}
Hi, I have successfully deployed "Virtual Control SL" on a few x86/64 machines now. However, I'd now like to deploy this to a Raspberry Pi (ARM64). To do this I prepared the Raspberry Pi5 with the following prereq's; * Minimal PREEMPT Debian * Latest Bootfirmware * full SSH access via non-root account * Podman * RedHat Cockpit with CODESYS LicensServer plugin up and running However, I can't seem to resolve copying the correct (deploy) Images as they wont show up in the CODESYS IDE I have added CODESYS Virtual Control for Linux SL and the CODESYS LicenseServer for Linux SL via the CODESYS installer on my DevBox. I open CODESYS > Tools > Deploy Control SL Next I enter the SSH targets IP and Credentials and for my RPi5 and it shows "Connected". In the next tab, Deployment, the dropdown box only shows one (1) image, which also is the incorrect CPU architecture. Only Virtual Control AMDx64 shows up (!?) while I expect to see the ARM64 based images for both Edge and Control. Has someone encountered this too? I'd like to hear other people experiences with Virtual Control deployment on ARM based architecture. attachment 1: AMD64 based deployment pulldown menu (correct images) attachment 2: ARM64 based deployment pulldown menu (incorrect images) regards,

Post by ivanj on Codesys V3 + Rpi + PCA9685 + two robot arms ^{CODESYS Forge talk (Post)}
greetings to everyone I have a system consisting of rpi3 computer with codesys v3 installed connected to one pca9685 through which the servo motors of the two robotic arms are connected (each robot arm has 6 motors) I managed to get that the pca9685 can only drive 4 servos on the first arm the other 2 on the same robot arm do not respond, nor do the remaining 6 they do not react on the other robotic arm. Power is connected to the pca9685 for motors of sufficient power or amperage. I tried to put another pca9685 but the same thing happens again. What is the possible problem?

Post by fless on Warning C0564 when compiling CNC project with variables program ^{CODESYS Forge talk (Post)}
Update: We managed to avoid the warnings by changing the order of initialization by adding an attribute to the GVL with the variables. {attribute 'global_init_slot' := '49989'} The variables are initialized right before the regular GVLs (default GVL slot 49990). Note to Codesys: I see the problem, Codesys needs to initialize the CNC objects before the GVLs so they can be used in the GVL. But then you can't use variables from GVLs in CNC programs. Maybe you could disable the warning in your generated CNC objects? At least a note for a workaround would have been nice.

Post by imdatatas on Auto Declare window disappears by itself in the Ladder editor ^{CODESYS Forge talk (Post)}
Hello Everyone, The "Auto Declare" window disappears by itself in the Ladder editor. For example, a new function block is wanted to be added to the Ladder editor. (For example; MC_Jog block and instance name will be fbMcJog). To do this, "Empty box with EN/ENO" is added to the ladder line from the Toolbox on the right and when you type MC_Jog in the empty box and press enter, normally the "Auto Declare" window appears and you are expected to be asked to write the instance name here. However, this "Auto Declare" window closes itself immediately, it does not wait for the user to enter a value or close the window. I often encounter this situation in many IDE versions. Does this seem like a bug? If anyone has encountered a similar problem while creating a new program name, function or function block instance name regarding the "Auto Declare" window and knows a solution, I would be glad if you could share it. Best wishes Imdat

Post by farren on How to stay in a method until something is finished. ^{CODESYS Forge talk (Post)}
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

Hi, I got good results with SMC_NCDecoder, SMC_CheckVelocities, etc. in a freewheeling task with lower priority (higher number). Still takes some time but I'm using many variables and loops in my g-code and more preprocessing like SMC_SmoothPath, SMC_LimitDynamics, SMC_CheckForLimits. PS: your buffer size seems a bit high for 34 lines of g-code

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.
