Hi there, I am getting troubles with a project. In the Hardware configuration I got some Lenze drives 9400. One of them got as status " Module not Found". Connection are good. ID Node of the Canopen network is also good. I don't find any reason for this status, nor any options to check.

Also had this problem when working on legacy project. My packege was CODESYS Code Generator ARM 4.0.3.0.package. To manage this I used PackageManagerCLI.exe. This tool does not validate certificates appearently. My command: "C:\Program Files\CODESYS 3.5.17.30\CODESYS\Common\PackageManagerCLI.exe" --profile="CODESYS V3.5 SP17 Patch 3" --install=""C:\Users\sample_user\AppData\Local\Temp\APInstaller\5wx1k02a.r2t\CODESYS Code Generator ARM 4.0.3.0.package""

Hi, gseidel. Thank you so much for your advice. I have created a program to preprocess G-code as follows 1.SMC_ReadNCFile2 2.SMC_Interpreter 3.SMC_CheckVelocities Then I put SMC_OUT_QUEUE in SMC_Interpolator. Where should I insert SMC_SmoothMerge and SMC_SmoothPath? Or are there any example link for it ?

Post by timvh on Codesys SVN ^{CODESYS Forge talk (Post)}
Minimum version is 3.5 SP19 Patch 3. See https://store.codesys.com/en/codesys-git.html But you could ask your PLC vendor if it is possible to program their PLC's which have Runtime version SP16 with development version 3.5 SP19 or higher (should normally be possible, but with Safety PLC's there could be some regulation limitations).

A bit of work but maybe possible to make your own driver using "CODESYS Control SL Extension Package". Look at the "ExternalIoDrv" example. It is installed in "C:\Program Files\CODESYS 3.5.20.0\CODESYS\CODESYS Control SL Extension Package" when you install the "CODESYS Control for Linux SL".

Post by timvh on Change the Opening Position of the Dialog using VU.FbOpenDialog ^{CODESYS Forge talk (Post)}
Probably best to call the FB continuously. So something like this could solve it: IF xOpenLatchSettingDialog THEN xOpenLatchSettingDialog := FALSE; fbOpenLatchSettingsDialog.xExecute := TRUE; END_IF IF fbOpenLatchSettingsDialog.xDone OR fbOpenLatchSettingsDialog.xError THEN fbOpenLatchSettingsDialog.xExecute := FALSE; END_IF TopLeftDialog.iX := 100; TopLeftDialog.iY := 23; fbOpenLatchSettingsDialog( itfClientFilter:= VU.Globals.OnlyTargetVisu, sDialogName:= 'visu_AlarmLatchSettings', xModal:= TRUE, pTopLeftPosition:= ADR(TopLeftDialog) );

Hello, I want to read a CSV file using the CSV Utility SL library, but I encounter an 'invalid_handle' error during initialization. What could be the cause? For my test program see the screenshot. I have purchased a license, and it is also installed on my PLC. Thank you in advance. Best regards, Stefan.

Hi Eschwellinger, sorry for so late reply but I found a solution back then; uninstall completely Codesys V3x64 and re-installed Codesys V3x32 to properly note the password I created and everything went ok. thank you for your suggestion and have a good day/evening Mike

Post by rjonker on codesys mqtt publish serialization ^{CODESYS Forge talk (Post)}
pbPayload is a pointer, which it expects to point at a STRING. If you point it at an address holding a different data type, it will just assume those bytes are part of a string and likely trundle along memory until it finds a null byte (0x00) that would normally signify the end of a string PublishMessage := BOOL_TO_STRING(boolVariable);

Post by installwhat on C0077 on one machine but not another ^{CODESYS Forge talk (Post)}
It doesn't load differently codesys seems to be behaving differently. Original version of ethercat master in project archive is 3.5.15.50, compiler is 16.4 as is codesys I'm using. It builds fine in vm and not on local machine. The reason is not obvious. It builds on local machine with ethercat master at 3.5.16.0. I'd really appreciate advice

Post by gatto on variables between two applications ^{CODESYS Forge talk (Post)}
Hello, I'm experimenting with two applications. I was able to start stop applications with the CmpApp library. Currently in my test the variables declared in the first application are not visible and writable in the second. I ask if there is the possibility of having variables that are visible both in the first application and in the second.

Post by timvh on Persistent Retain Variables Not Visible in Online View (WAGO PFC100 + CODESYS) ^{CODESYS Forge talk (Post)}
It is a known issue. It only happens with CODESYS and Wago controllers and the Persistent Variables. It seems related to using 64 bit variables in the PV list (e.g. LREAL). Internally in the PLC everything works okay. It is just a monitoring issue.

While trying to install CODESYS 3.5.17.30 (64-bit) on my Windows 11 computer, I'm getting the errors below. The first error occurs near the end of the installation. Once you bypass it, the installation returns the second error. Do you have any suggestions for a solution? By the way, I've tried this on several PCs, but I haven't found a solution.

Post by egret on Issue with J1939, PGN 65267 (Vehicle Position) ^{CODESYS Forge talk (Post)}
I have a J1939 network (ISOBUS) connected to my PLC. I can receive various PGNs such as 65256 (Vehicle Direction/Speed) and 65254 (Time/Date). However, I cannot receive 65267 (Vehicle Position). PGN 65267 (VP) contains SPN 584 (Latitude) and SPN 585 (Longitude). On the network both SPNs return a value of -210 (meaning the CAN message payload is zero in both cases). The conversion settings are the default values and appear to be correct (see attached screenshot). Using a CAN analyser I can see that PGN 65267 (Vehicle Position) is being transmitted over the network with valid (non-zero) data that matches the latitude and longitude coordinates I would expect. I've created a program to read the raw J1939 data and this also returns valid data. It seems that the Codesys J1939 database has a problem with reading PGN 65267 messages. Can anybody else confirm this? I'm using Codesys Version 3.5 SP16 Patch 5.

Post by user3000 on Can't find an Extended Pulse Timer (TP and LTP) ^{CODESYS Forge talk (Post)}
Hello, For my program I need an extended pulse timer, which can be referred to as a retriggerable pulse timer. Where every rising edge of the input resets the elapsed time zero, extending the lenght of the output pulse. The Codesys pulse timer (TP) is a one-shot timer and only resets the elapsed time with the falling edge of the input. There is also a pulse timer (LTP) in codesys, but in my simulation it was also functioning as a one-shot even though the description sounds like LTP should be retriggerable. I have uploaded some timing plots from another PLC program for reference. I am looking for a timer equivalent to the "TEP" diagram. Is there an Extended Pulse Timer in Codesys? Maybe there is a way to manipulate the input so it resets the elapsed time outside the function block?

Post by xgongx on What is the insights of IoDrvEtherCAT.DCInSyncWindow? ^{CODESYS Forge talk (Post)}
It is well known that you need to increase the value of IoDrvEtherCAT.DCInSyncWindow to solve the "Fieldbus lost synchronicity" issue. In the official document, IoDrvEtherCAT.DCInSyncWindow is explained as the toleration of a certain jitter. But the official document doesn't explain what kind of the jitter is. Is it the jitter of DC sync deviation, master timer or something else? It is very important to know the insights of IoDrvEtherCAT.DCInSyncWindow. For example, if it is the toleration of DC sync deviation, and the official recommending value is 200us for CODESYS SoftMotion. It means maximum of DC sync deviation is 200us. It is unacceptable for some high precision motion control tasks, for example high speed gear task, etc. Increasing the value of IoDrvEtherCAT.DCInSyncWindow will increase the deviation of motor rotation sync if it is the toleration of DC sync deviation. So, would anyone tell me what the insights of IoDrvEtherCAT.DCInSyncWindow is? Thanks.
