Post by jonasz on Discontinuity of A/B/C axis movement. ^{CODESYS Forge talk (Post)}
Hi, My problem was related to the behavior of the modulo axis, but maybe you will find something useful from what I write. The solution lies in path processing. Codesys offers a G-code analysis tool. Insert a CNC object into the project. The CNC settings object will be added automatically. By inserting appropriate processing modules into the CNC settings object and parameterizing them, you can test the behavior of the axis. When the effect is satisfactory, remember to add the module from CNC settings in the correct order in the processing path. Each CNC machine case is different. You need to spend some time to get your design tailored like an Armani suit. Good luck.

Post by eurowolf on SoftMotionLight Lizenz nach Programmupdate weg ^{CODESYS Forge talk (Post)}
Hallo, auf einer Sabo MKS855.20 habe ich die SoftMotionLight-Lizenz installiert. Zur Programmierung nutze ich V3.5 SP16.0. Die im Projekt verwendete SML 4.7.0.0, SML_Drive_CAN_GenericDSP42 3.5.7.0, CANopen_Manager_Softmotion 3.5.16.0. In der Regel habe ich keine Probleme mit der SoftMotionLight, nur bei dieser Anlage ist es mir jetzt zum Zweiten mal passiert, das ich ein Programmupdate einspiele und die SML in den Demo-Modus wechselt. Die Lizenz ist doch auf der SPS gespeichert, warum wird dann behauptet, dass die SML im Demo-Modus arbeitet. Da ich z. Zt. beim Kunden vor Ort bin und dieser sich im Ausland befindet, benötige ich kurzfristig eine Lösung. Auf E-Mails bekomme ich leider keine Rückmeldung.

Post by westcountryewe on Persistence Variables missing and DO NOT retain from Persistence Channel when using Boot Application ^{CODESYS Forge talk (Post)}
We've been experiencing an issue through SP18, SP19 and now SP20 where the Persistence Variables do not retain if we upload our program via a Boot Application. If we use the exact same program, and perform a Direct Upload via the Laptop and Ethernet connection, the Persistence Variables work exactly as expected. I have submitted 2 bug support tickets but I haven't had a response back from Codesys. Has anybody experienced the same issues and discovered a workaround? We have a requirement to utilise the Boot Application method because of logistical restrictions of being able to get out to every site, so at the moment it's a bit restriction.

Post by alexgooi on FB_INIT in library ^{CODESYS Forge talk (Post)}
Dear Forum, I currently have a challenge. I have a library with some communication classes. These communication classes need to be linked to an interface like this: Devices_and_controllers.Comm_Frame.Modbus_GVL_Link.KNX_TCP[Interface_Index] := THIS^; This is executed via a FB_Init() method. When I try to do this in a program this works fine. But when I declare the FB_Init() in the library the FB_Init() method is being called but the link is not made (interface still has the value 0000000000). The Objects and interfaces are defined in the library (GVL), so I’m assuming the data should be there. When I call the FB_Init method explicitly in the program it also works fine. Whys is this not working when it is all defined in the library? And is it even possible to create a structure like this in Codesys? Kind regards Alex

Post by marckl on Bosch BME 280 bzw 688 Sensor per I2C Bus steuern und Daten in Codesys verarbeiten ^{CODESYS Forge talk (Post)}
Hallo allerseits, Ich möchte für mein Projekt einen BME 688 Environmental Sensor benutzen, aber weiss nicht wie ich ihn in Codesys ans Laufen bekommen soll. Der Händler hat auf der Website eine Anleitung um ihn in der Kommandozeile des Raspberry Pi´s laufen zu lassen, das funktioniert auch super. Der Sensor ist per I2C Bus angeschlossen. Wie kann ich jetzt in Codesys die Sensordaten auslesen? Ich habe dies schon viel recherchiert und habe gesehen, dass jemand schonmal das Gleiche mit einem BME 280 probiert hat, allerdings konnte ich nicht nachvollziehen wie er den ans laufen gebracht hat. Ich hoffe mir kann jemand helfen

Post by lzml on Safety ^{CODESYS Forge talk (Post)}
I have a problem with a project that uses EtherCAT Safety. The project is developed with CODESYS version 3.5.19.20, runtime 3.5.18.30, safety CPU EL6900 4.3.1.0, TCEL6900FBS 3.5.1.10, IODrvEL6900 4.3.1.0, IODrvEtherCAT 4.1.0.0. The safety project works correctly, but when I download the PLC project for modifications, the ESM objects are no longer aligned with the states inside the safety program. Specifically, inside the safety program, they are seen as true, while outside the safety program, the state is reported as false, but not for all ESMs, only some. I have already tried to completely redo the safety from scratch, but nothing has changed. Any solutions? Thanks

Post by dhumphries on Rounding error in simple addition ^{CODESYS Forge talk (Post)}
Thanks for the response, as I've thought about this problem over the last month I began to suspect this was a problem with not being able to exactly represent .1 as a 32 bit binary number. I think I've found a work around by making the number an integer, then dividing it by 10 and storing that value as a floating point number. There is still an issue with the value not being exact somewhere in the 8th or 9th decimal place, but because I'm incrementing an integer value then dividing it, the error doesn't compound.

Post by viksym on Get text from textlist ^{CODESYS Forge talk (Post)}
Does anybody know how to get a specific text from a text list within a program. Obviously it works in a visualization, but because I will have an HMI that has it's own system and I will have to send variables to this HMI via an OPC UA connection, I need to be able to get a text into a string. I tried using the VisuElems like this, but it only returns an empty "" and nothing else. IF trig THEN sText := VisuElems.cmpDynamictext.DynamicTextGetDefaultText(ADR(sTextList), ADR(sAlarmID))^; //sText := VisuElems.cmpDynamictext.DynamicTextGetText(ADR(sTextList), ADR(sAlarmID))^; trig := FALSE; END_IF Any help and idea is highly appreciated because I am getting desperate here.

Good afternoon to everyone; I'm stuck with this error and I don't know how to get out from it... I tried several time googling for alternative systems to control the PLC applications and resets but without success. I would like to realize the possibility to reset the CPU and to start/stop the applications as it was possible with the SysPlcCtrl23, but this library is no longer supported in 64 bit systems and it seems due to the cmperrors interfaces sub library that was included in the above said one. Someone found a work around for this issue?

Hello, i currently want to use a wago 750-8102 with the "codesys control for pfc100" runtime. I want to add the devices connected to the internal pfc100 bus via the "search devices" tab. This was reccommended in the following thread: https://forge.codesys.com/forge/talk/Deutsch/thread/7701332199/ But whenever i try to search for devices codesys just doesnt find anything and i cant close the "search devices" window. Has anyone got an idea what the problem might be? I already tried adding the devices connected to the pfc100 manually but the bus just doesn´t start. best regards Moritz

Post by matt-purcell on Which Lib to use, connect to a socket with URL instead of IP address ^{CODESYS Forge talk (Post)}
Hello, I have a new project and I need to connect to a TCP socket using the URL instead of an explicit IP address, myendpoint@mydomain.com Which library is best suited for this? This is for a new enterprise project, the endpoint is a server in a datacenter running some real time application. We have big IP, it will automatically reassign the IP address to the backup server if a crash occurs so an explicit IP won't work for me. I've done this in RS logix, working now to migrate that code over to codesys. Thanks in advance!

For anyone confused with the process visit this link (the bottom section about creating a .pfx file) https://content.helpme-codesys.com/en/LibDevSummary/certificate.html#import-of-client-certificates-with-private-key. I solved this problem by creating a .pfx file and importing it into the security store under 'Own Certificates'(must have SP18 or newer to import .pfx). I used a gitbash shell to enter the openssl command that created the .pfx file. Once you import the file, in your TLS context, set your 'sUseCaseName' to be the same as the name listed in the 'Information' column of your imported certificate. This did it for me

Post by ron-rp on Errors with VisuUserManagement library ^{CODESYS Forge talk (Post)}
Hi all, I've played a bit with the VisuUserManagement library, and some other security option in my project, and I started getting this error when logging in - see attached pic. something to do with a specific screen in the library - VUM_Login. Also, Codesys started to ask me to log in to the library when logging in, asking to log in as user of the groups Maintainer or Owner, which I dont know either users (attached pic). when I close the login screen and try to log in to the PLC again, everything works again until I close and open Codesys. I do use user and password to login to the PLC, and this login screen is fine I know the user and pass I setup. anyone know what did I do wrong here and how to fix it?

Post by rafael on Wbm/runtime and visualization login ^{CODESYS Forge talk (Post)}
Hello everyone, I’m trying to understand if it is this way or I can change it. I’m making a PLC code and visualization screens, the ideia is to operate via webvisu some controls. So i made a code, made some screens and when i try it in my web browser, first it asks me to insert te user and password of the wbm/runtime of the plc (user: admin, password: wago by default), then i can acess my screens but I have to login again with the user and password that i created in the visualization user managment. My question is: is there a way to disable this first login to the visualization screens (webvisu)? Or create another user/password for this first screen? I have a PFC200 and a Edge Controller, both are working the same way. Thanks in advance Thanks
