Post by atcprojectteam on Modbus Function Code 15, writing multiple coils ^{CODESYS Forge talk (Post)}
Hi all, I am using an RSTI-EP I/O card along with the EPXMBE101 Modbus/TCP network adapter. I have a Control Standard L license. I successfully connected to the I/O card via Modbus and can read inputs without any issues. However, when I try to write to the digital output modules using function code 15, I am unable to make any changes. Here’s what I have done so far: I created a small project using Structured Text. I set up Modbus channels (as shown in the attached image) and mapped the pins. When I use cyclic mode, the connection results in an error. However, when I use the rising edge, the connection works, but I don’t see any changes on the I/O card. For the output module, I assigned one bit to high. After that, I ran CODESYS Control Win V3. (Should I be running the PLC as well?) I built the program, but I am not receiving any response from the I/O card. Could you please advise on what might be causing this issue?

Post by pernockham on Inheritence of struct, ^{CODESYS Forge talk (Post)}
Im looking for a way to define predefined version of the same structures through "extends"/inheritance. What I want to do is best shown with an example: TYPE log_item_val_type : ( BOOL_ := 0, INT_, REAL_, STRING_ ); END_TYPE TYPE LOG_DATA_BASE STRUCT val_type : log_item_val_type; (* value, name etc *) ENDSTRUCT ENDTYPE (* this/below is not possible as I understand from the compiler?? *) TYPE LOG_DATA_BOOL extends LOG_DATA_BASE : STRUCT val_type : log_item_val_type := log_item_val_type.BOOL_; END_STRUCT END_TYPE TYPE LOG_DATA_INT extends LOG_DATA_BASE : STRUCT val_type : log_item_val_type := log_item_val_type.INT_; END_STRUCT END_TYPE etc. for LOG_DATA_REAL and ..STRING. The system will not allow me to "re-define" "val_type" however. Instead I must do the work-around of defining four different types with all fields individually defined. The benefit if I could extend the base item would be that Im (more) sure the structures are identical. In usage I can call in a specific type rather use the base type and assign which type. Usage by pointer/ref to log_data_base would also be easier.. (* Usage: *) log_data : log_data_int := (name, value etc.) (* Instead of: *) log_data : log_data_base := (name, value, val_type).. Is this possible to achieve in some way that I have missed?

Post by egau on Enable and Disable Project IO programmatically ^{CODESYS Forge talk (Post)}
Hi @eschwellinger, I tried this with Modbus COM slaves. I was able to disable them (slave becomes greyed out in the device tree), but the DED.Reconfigure "eError" output shows "NOT_SUPPORTED". After this, when I tried to re-enable the slave, it did not work (device stayed greyed out in the device tree), and the DED.Reconfigure "eError" output also showed "NOT_SUPPORTED". Is there something to do about this, or the device just doesn't support reconfiguration? P.S: I tried this running locally on my computer (not in simulation mode). So of course I was not physically connected to the devices. I have two similar projects, but one of them doesn't have the Modbus_COM devices. I know I can "Exclude from build" the devices for that project, but I would really prefer not to do this if possible. I would prefer to dynamically toggle a configuration variable that would enable or disable the slaves.

Post by pernockham on Persistence Manager: Config File not found? ^{CODESYS Forge talk (Post)}
Back in november I paused this, but wanted to reattempt using the persistent manager, the behavior is still the same. Most "login attempts" s are stopped with the message "One or more errors occurred" but I have no idea what that error might be. The only clue is this message is presented while the lower left status box says "Generating code...: relocation pou". For clarification. Build/Generate code is successful, no errors. Error appears when I try to download/login (physical or simulation) to a device. I did manage to login (in simulation mode) at one point, but then the error message "PersistenceChannel: Config file not found!". And no persistence files were created. I have done device-tree/reset-orgin also clean/clean all etc. Removed/re-inserted persistance manager. Behaviour is just the same. Removing Persistence Manage and everything is working OK. Is there possibly more info somewhere about the "One or more errors occured"-message?

Post by mondinmr on Unexpected behavior in cyclic encoder read method during INT overflow (wrap-around) ^{CODESYS Forge talk (Post)}
Hi everyone, I’m investigating a potential issue with a cyclic method we use for reading incremental encoders in our libraries. I’ve come across two implementations that, at first glance, appear to perform the same operation: motionUnit.vlPositionActualValue is UINT due strange encoder type. Version A METHOD PROTECTED cyclicReadField VAR_INST actPosFieldOld: INT; rI: INT; delta: INT; END_VAR rI := TO_INT(motionUnit.vlPositionActualValue); delta := rI - actPosFieldOld; m_actPosRaw := m_actPosRaw + TO_LREAL(delta); actPosFieldOld := rI; IF settings.velocityFeebackMapped THEN m_actVelRaw := TO_LREAL(motionUnit.velocityActualValue); END_IF Version B METHOD PROTECTED cyclicReadField VAR_INST actPosFieldOld: INT; END_VAR m_actPosRaw := m_actPosRaw + TO_LREAL(TO_INT(motionUnit.vlPositionActualValue) - actPosFieldOld); actPosFieldOld := TO_INT(motionUnit.vlPositionActualValue); IF settings.velocityFeebackMapped THEN m_actVelRaw := TO_LREAL(motionUnit.velocityActualValue); END_IF Both use INT and the same delta logic, so they seem equivalent. However, when an overflow (wrap-around) occurs, version A continues correctly as expected, while version B unexpectedly resets to -32768 without a clear reason. Has anyone experienced similar behavior or can shed light on what might be happening here? It almost seems as if the cast to LREAL is being applied before the calculation — but that would be illogical and potentially very dangerous in many situations! Thanks!

Note it is now part of Codesys IIoT Libraries SL in the form of Web Client SL, but I am not using this version. I was sending Content-Type: application/json, HTTP POST using a HTTPS URL. No issue observed initially, successful operation. At some point operation stopped and the codesyscontrol.log file started to accumulate errors: ERROR: TlsCreateContext2: Failed to save context. An application reset failed to resume operation and I was unable observe any TCP connection forming to a destination port 443. The error appeared as a TCP_INIT error. I can find no details as to what may have happened or why a reset of the PLC application did not resume operation. Testing with a curl operation proved to be successful, so I am confident there was no fundamental networking issue preventing a TCP connection forming. The solution was to reboot the hardware itself, but this is not satisfactory in the long term. Is there any description of the TLS error I received? Is there any suggestion here that there might be an issue with certificates? Any advice or information is appreciated.

Post by erictur on CODESYS Control for Linux ARM SL (32 bit) on Moxa UC-3100 IPC ^{CODESYS Forge talk (Post)}
UC3100 comes with Arm Cortex-A8 1 GHz and belongs to Moxa Industrial Linux 1 (Debian 9) for Arm-based Computers. I tried to install the CODESYS Control for Linux ARM SL (32 bit) on Moxa UC-3100 IPC. Unfortunately, the Third-party requirements: - libc >= 2.27 (required by CodeMeter Runtime) of the CODESYS Control for Linux ARM SL cannot be met on the Debian 9, which comes with glibc 2.24. I read the post by @johnlee (Getting Start with Codesys Control for Linux SL) (https://forge.codesys.com/forge/talk/Runtime/thread/0a515ced3f/). Where he discusses installation of CODESYS Control for Linux ARM SL on Debian 9. There was CODESYS Linux runtime v3.5.14 availble and it was successfully intalled on the Debian 9. However, the CODESYS Store has the oldest version V4.1.0.0 32 bit available. There is no way to find the CODESYS Linux runtime v3.5.14. So is there any work around for this? Or I cannot install the CODESYS Runtime on any of the Moxa IPCs based on the Moxa Industrial Linux 1 (Debian 9)?

Post by timvh on Current Visu name without Current Visu Variable ^{CODESYS Forge talk (Post)}
To get the current visu for all your individual web clients, you could iterate over them, using the same library 1) Create a new function block which implements VU.IVisualizationClientIteration 2) Create an instance of this function block + add an instance of the "iterate" function block fbIterateCallBack : FB_IterateOverClients; // this implements VU.IVisualizationClientIteration fbVuIterate : VU.FbIterateClients; // this FB iterates over all clients 3) Call the fbVuIterate and set the reference to the call back FB. Then it will automatically call the method "HandleClient" of this function block. fbVuIterate( xExecute:= NOT fbVuIterate.xDone, xDone=> , xBusy=> , xError=> , itfClientFilter:= VU.Globals.OnlyWebVisu, eError=> , itfIterationCallback:= fbIterateCallBack); In the HandleClients method you can use the property of the interface of your webclient to which page it is currently on: sCurrentVisuOfClient := itfClient.CurrentVisuName; 4) Optionally from here you could also set the visu for the webclient, but this might be obsolete, because the other function block is now available... xQueryOK : BOOL; xChangePage : BOOL; itfVisuClientRawData : VU.IVisualizationClientRaw; xQueryOK := __QUERYINTERFACE(itfClient, itfVisuClientRawData); IF xQueryOK AND xChangePage THEN VisuElems.g_VisuManager.SetMainVisu(pClientData := itfVisuClientRawData.ClientDataPointer, stVisu := 'Visu2'); xChangePage := FALSE; END_IF

Post by gseidel on AXIS_REF_SM3 Error Codes? ^{CODESYS Forge talk (Post)}
Hi SLUCodesys, dwErrorId is a drive specific error number. The drive documentation should be consulted to interpret it. (Note that you should use MC_ReadAxisError to read this error, see https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Diagnostics/MC_ReadAxisError.html. Accessing the internal variable will result in outdated values if the acis error is not mapped by PDO and is not recommended in general.) uiDriveInterfaceError holds errors of the SoftMotion driver for the drive. It is also an internal variable, not intended for direct access. It is intended for logging, the PLC log will contain the drive interface error, consisting of this number and an error text. My recommendation for handling axis errors in the CODESYS application: 1) Use MC_ReadStatus on the axis to find out whether it is in state Errorstop 2) If in Errorstop, there are two possibilities: an error reported by the drive (MC_ReadAxisError) or an error of the SoftMotion function blocks (output MC_ReadStatus.FBErrorOccured). 3) If there is no drive error, you can use SMC_ReadFBError https://content.helpme-codesys.com/en/libs/SM3_Basic/Current/SM3_Basic/POUs/Diagnostics/FBError/SMC_ReadFBError.html Best regards, Georg

Post by nicetuxedo on Can not activate license on Raspberry pi ^{CODESYS Forge talk (Post)}
Hello everyone, I'm hoping for some assistance with a license activation issue: a software crash has left my license in a strange state. Here is the sequence of events: I purchased a new license for the Raspberry PI from the official CODESYS web store. I opened the CODESYS and started the online activation process using the ticket number I received. During the activation, the CODESYS software threw an exception and crashed. I was not able to see if the activation completed. After restarting CODESYS, I attempted to run the activation process again with the same ticket number. The License Manager now gives me an error stating that the ticket has already been activated/used. I am now stuck because my installation is not licensed, but the activation server believes my ticket has been consumed. Has anyone encountered this before? Is there a way to have the ticket status reset?

Post by axilleas on SMC_Interpolator + SMC_controAxislbyPos ^{CODESYS Forge talk (Post)}
dear all I am working on a very generic gantry system (virtual drives + win v3 control) reading gcode from external file. In order to stop the interpolator function from running when gaps are detected, SMC_controlAxisByPos FB has the bStopIpo output which according to the manual is connected to the Interpolator's bEmergencyStop. Lets assume that the axis are parked in position X1000 Y1000 and the initial G code movement is G00 X500 Y500. The normal behavior is to travel from the actual x1000 y1000 to G00 X500 Y500. The SMC_Interpolator always gets the X0 Y0 as the initial position, meaning that the bStopIpo is active until the axis are in X0 Y0 and the release the interpolator to set the new positions to X500 Y500. Is there a suggested method to solve this behavior? bonus question: I get a lot of bStopIpo during standard interpolation movements (not gaps). While working with virtual axis this is not a problem but when real axis are installed this will be an issue. What exactly triggers the bStopIpo output? Slow axis accelerations compare to Gcode defaults? Kind Regards

Post by danieldiaz on Problem with FB execution ^{CODESYS Forge talk (Post)}
Hello everyone, I've been working on a system which needs an error function, with this purpose I've created a FB programmed in LD, after debugging I run the simulation. It seems that the variable linked to a coil doesn't change the value when the contacts are associated to input variables. When I use internal variables the logic works properly. I don't know if the problem is related to the variables definition or with the logic program. As you can see in the image, I1 and I2 are variables declared on the FB, the rest are input variables. If I force the eStop and Reset signals to TRUE the coil value should change, but it doesn't. However in the second network if I1 is TRUE the coil change to TRUE as it has to be. To sum up, my doubt is why that coil doesn't change its value? I would like someone to shed a light on this. Thanks!

You ofcourse then need to add some code arround it that does something with the trigger and writes it back to FALSE again. If you want more flexability you also could use pointers instead of using the IN_OUT FOR i := 0 TO 200 BY 1 DO address := address_Input + i * SIZEOF(*Put type here); IF Address^ <> Old_Value[i] THEN Trigger[i] := TRUE; Old_Value[i] := Address^; END_IF END_FOR

Post by salvadegianluca on How to use TON inside an FB that is instanced within a Visu page ^{CODESYS Forge talk (Post)}
Hi everyone; I'm building a project in which the drag of the mouse over some controls (or the click event) changes the background color of the control items; this change of color is made with an FB that assignes a color code to the background with MUX command based on the value of an enumerator, this part is perfectly working but, when I'm using a touchpanel instead of a web visu (controlled by a mouse) I get into some issues as it seems that the touch operations are not triggering the MouseEnter and MouseLeave properties as it's done with the mouse.... For this reason I'm trying to add a TON to my FB and, if the enum that changes color remains at the same state for more then 3s I'm automatically resetting it to it's "0" so the item gets back the not selected color. Anyhow it looks like the TON function from library is not working in these FB that are instanced in the various visualizations, as instead they do if I create some instances within the POUS. Anyone has ideas of how to make them work?
