as a workaround just plug your USB key to the CODESYS PC - and activate the ticket by the browser license.codesys.com

Post by mwandy on Codesys Project Protection ^{CODESYS Forge talk (Post)}
I'm having trouble finding clear answers on this. I'm looking for a way to make a Codesys project password protected so that if the project is distributed it can be used to log into a controller to view and debug logic. At this same time I want to prevent the project from being saved as well as edits being downloaded to the controller. Basically I want to make a whole project view-only. What is the beat way to achieve this? I have had minor success with access rights, which solves the problem with trying to login if the project doesn't match what is in the controller. However with this solution, edits can still be made and saved, possibly corrupting the core project, preventing future logins. Any suggestions?

Post by sachem on Problem retain values Weidmuller UC20-WL2000 ^{CODESYS Forge talk (Post)}
Good afternoon. I am working with a weidmuller uc20-wl2000 controller, using a codesys license. We made a ladder code to control a process, and it works well, but we want some variables to remain stored even when the controller is turned off. We tried to use retain variables, but at the time of loading the program, when we went offline from the controller, the program was deleted, it did not remain in the controller, and in the same way if we turned off the controller. In addition to this, when we tried to program it again, the program would not stay loaded and began to present errors with the opc-ua communication. What could be causing this problem? How can we maintain the values of the variables without damaging the program or affecting the controller? thank you

Post by dkugler on build (F11) / generate code using a python script file ^{CODESYS Forge talk (Post)}
thank you very much! I found the generate_code methode, but struggled with the primary and active_application. With this expample I will be able to play around. If the code generation takes a minute or more I often switch to other programs and don't notify the process is finished. So now I'll get an alert and will switch back immediately. My next little project will be, to beep different if there are errors and a seperate script to do the download incl. the user management data base without stopping at the dialogs asking for onlinechange/complete download and overwriting an existing database and as goody, play a beep/sound again.

Post by niallel on Continuous MC_PositionProfile ^{CODESYS Forge talk (Post)}
Hi, Is it possible to have a MC_PositionProfile that runs continuously again and again without stopping the motor and starting again. I have a profile that contains about 50 steps that I want to repeat. At the end of each run the motor comes to a stop before the next one starts. My code checks for Done, then resets the Execute to False before setting Execute to True to run again, and I think this is causing the motor to go to standstill before starting again. There doesn't seem to be a BufferMode option like with MC_MoveAbsolute. Is it possible to do this? Many thanks,

Post by esave on OPC UA Server with on Codesys + OPC UA Client on Labview ^{CODESYS Forge talk (Post)}
Hello everyone I want a communication between my PLC as an OPC UA Server and Labview on my PC as the OPC UA Client. I have an Festo CPX-E-CEC-C1-PN PLC and I have the OPC UA Toolkit from Labview. I created some Variables for testing (see picture 1) on Codesys. I tried to use this Labview block diagram (see picture 2) but I cant connect the PLC to it. What do I have to type in the Server Endpoint URL and what in the Node ID? Is this a good way for communication with a PLC to a PC? If not is there another way?

Post by wiresplus on How to Connect / Go Online without re-downloading the project ^{CODESYS Forge talk (Post)}
Hello, I have a PLC in a remote location. I can connect to it, but when I use a different PC, it asks me to re-download to the PLC - which will a) interrupt production and b) cause version issues. Codesys being open-source, if someone else has made changes, I need to be able to connect, upload the current project, compare it with mine and then decide what next. Every time I connect, it says Warning: An application 'Application' is currently in RUN mode on the PLC. As there is no matching compile information, this existing application needs to be replaced. Click 'Yes' to download the latest code or 'No' to abort. What am I doing wrong?

Post by valenting on Can't use new licensing with Raspberry Pi ^{CODESYS Forge talk (Post)}
Hi, I'm using Codesys control for Raspberry Pi in the latest version (4.11.0.0) When I try to install a license with the new application-based licensing, I have an error "returncode 403046401" (using codesys SP18) I updated to codesys SP20, and now I get the following error: "The selected conainer [0]: SN=..., Version=1.18, Chip=0, Rev=0 does not fit to your ticket. Please select a suitable one." The license I'm trying to install is a Codesys Control Basic L license, with a Codesys Visualization L option, according to the needs of my application. What can I do to activate my license ?

Post by m83coding on Raspberry Pi Codesys SPI Master ^{CODESYS Forge talk (Post)}
Hello, I am trying to control shift registers 74HC596 and 74HC165 via Raspberry PI with SPI interface. So far I did it with a Microcontroller and now I wanna upgrade my Projekt with Raspberry Pi and Codesys Software to be more flexible. I tried to adapt PiFace Function Block to just send or recive a 8 bit via SPI interface of the my Raspberry Pi. With following code (see attached screenshots) * PLC_PRG * PiFaceDigital * PiFaceDigital.write8 * PiFaceDigital.read8 I have a signal at SCK and MOSI pin of the PI, so far so good. But I really struggle with the unterstanding of the code. Is there some detailed description of each line of code? Or is there somebody in the community who can explain each line of code? Or is there a more simple way to send / recive 8 bit via SPI? Manuel
