Post by rmaas on Responsive Design Example ^{CODESYS Forge talk (Post)}
Hi, I just tried the example project with control WIN x64 and for me this is working correct. The only difference is that it is showing 'TabletPortrait' when i hold my smartphone in portrait mode and 'Monitor' when i hold my smartphone in landscape mode. This is because smartphone resolutions have increased i guess... You could check what resoution is detected and change accordingly in IsSmartphone method.

Thanks for the answer Tim. I am using the codesys version 3.5 SP16, is this also affected or only after version 19? But now at leastI know that is an acess problem to the file and not something else. Unfortunately the link you posted on 2023 are now dead, but I will investigate!

I've also noticed that when I turn off "enp1s0", suddenly the source IP for the ModbusTCP changes to that of "enp2s0", which is what makes sense to me. When I turn it back on, the source IP remains that of "enp2s0".

Hi, i am interested in this thread and have tried a couple of the above examples in to determine remote webvisu access. I am having trouble getting the lastusage variable to refresh during runtime? It seems to only log the last usage at initialisation and that is it? how do i gain ongoing access to the time variable as the code is running? Thankyou.

Get a different sensor that is 0-10V and 0-350 Bar. There is nothing you can reasonably do to boost the range of the sensor, and the PLC will only ever be 0-10V. Take away is to always be careful to match the sensor and PLC input ranges in the future.

I made hardware reboot and it still not working. I also tried Persistence Manager which need Application Composer Single License but Codesys support said that my runtime do not compatibile with it and it will avaiable in 2025 only. So I hope I will figured out how to use this code.

I have a Codesys environment running and would like to inject code into the running environment at the same time using a code generator with Python via the console. So far I can only start a new Codesys instance with Python, but not access an already running one. How can I access the running Codesys instance?

Hi if you add in (ttyAMA0 should fit to your HAT's device [SysCom] Linux.Devicefile.1=/dev/ttyAMA0 to /etc/CODESYSControl_Usr.cfg since 4.12.0.0 version /etc/codesyscontrol/CODESYSControl_Usr.cfg then access in CODESYS with Com1 should do it. Keep in mind that only adapters work (for RS485) which do determine the send/receive direction in hardware

okay, the weird thing is the driver is only continuous running when i enable debug output. if debug is not enabled it's continuous switching from running to not running. i will check again and download the libraries Which versions of libraries do you use, can you send a screenshot?

Post by sigurdrb on Codesys SP20 and professional developer edition ^{CODESYS Forge talk (Post)}
Hi, I updated codesys IDE to the newest version, but I lost the "professional developer edition" in the process. It still works fine on the older version I have been using previously. Do you know what the easiest process for getting the same integration in the newer version? It is only the GIT integration that I really miss.

I don't have a multiplexer so it very weird that it connects with that multiplexer. If i do a I2C scan on the PI terminal, i only get the device addresses 0x48 and 0x51. One for the ADC and one for RTC. I will try again with your libraries

Post by manuknecht on Persistence Manager does not save alphabetically first value ^{CODESYS Forge talk (Post)}
I have several libraries which contain values that should be saved on a PLC. As apparently no Persistent Variable List is available within Libraries, I use the Persistence Manager to create a Persistence Channel in the Project which imports the library. I then specify the persistence channel in the library using the {attribute 'ac_persist':='PersistenceChannel_CT'} specifier. This generally works very well and gives me exactly the properties I require. However, it came to my attention that the (alphabetially) first value from the library is not saved in the created ASCII file. When checking the content of the Persistence Channel, it shows all the variables as defined in the library. But the created file does not contain the first value and it is not restored after restart or reset. (see attached picture) I disabled Periodic Saving and set xSaveOnChange to TRUE and so the file usually updates immediately after changing one of the values. When changing the first value, it does not update which is consistent with this value not being saved. I also created a sample project and library from scratch which shows the same issue both using a Raspberry Pi and using a Linux machine. Does someone know what the reason for this could be or did someone make similar experiences? Looking forward to hearing your suggestions. Thanks in advance and best wishes Manuel

Post by dantheman on Connecting to SoftPLC Only Works By Turning Off Modbus Ethernet Port ^{CODESYS Forge talk (Post)}
I have an IPC with 2 ethernet ports and 1 Wi-Fi. I'm using ModbusTCP with the ethernet port named "enp2s0" connected to my remote I/O. This works fine when testing with Python and also works with CODESYS, but CODESYS is only able to scan for the Linux SoftPLC when I turn off the "enp2s0" interface. In other words, I can't get online with the IDE if I want my ModbusTCP comms to run with CODESYS. I'm using a Linux SoftPLC that has the following entry in CODESYSControl.cfg, hoping that this will allow me to connect with "enp1s0" or "wlp3s0", and leave "enp2s0" for field comms, but this seems to only make the source IP of the ModbusTCP comms to be bound to "enp2s0". That last point is the case only if I don't restart the service, but if I do restart the service after changing the config file, the source IP for the ModbusTCP comms then becomes the one for "enp1s0", which is very confusing to me: [SysSocket] Adapter.0.Name="enp2s0" Adapter.0.EnableSetIpAndMask=1 On the device list, I only have "enp2s0" given as the ethernet device that has the ModbusTCP master & slave beneath it, shown in Screenshot 1. On the IPC, I can ping the ModbusTCP client (remote I/O) from "enp2s0", and I've attached a Wireshark capture of running ModbusTCP from the CODESYS runtime as Screenshot 2, 3 & 4 (again, I can't get online when this is running, I have to turn off "enp2s0" to connect even when it's idle and I don't have an active TCP session with my Python tests). Like I explained above, the source IP is "enp1s0", even though the ethernet device on the project is "enp2s0". I was lucky to catch the red message that showed the source IP that makes sense to me (the one for "enp2s0"), but for some reason that connection was reset and I never saw that packet again. I've also tried this with Auto-reconnect both enabled & disabled, for the ModbusTCP Master device. I also have to turn off "enp1s0" and then turn it on, just so that I can have the ModbusTCP comms running from "enp2s0" (which is not intuitive in any way to me, I'd love some help understanding that phenomenon as well) in the weird manner that I've described above. I would be very appreciative if someone can help me figure out this pickle. I'd love to just connect to CODESYS through my Wi-Fi interface and leave my ethernet ports for field comms.

Hi TK_Jenssen did you found a solution I am setting up the samelike gantry only with two z-axes which are mounted on fix position with an X axes between the two z-axes. The movement and position of both z-axes must be very well aligned and calibrated. Maybe also to be adjusted by programming. Can you sent an example of your solution?

Hello good morning everyone I would like to ask a question, is it possible to directly connect a device that only contains modbus RTU communication through an R-45 connector, directly to the PC? Or would you need an intermediate device to achieve communication? It would be of great help to me because I cannot achieve communication between the Codesys simulator plc and a Fuji Frenic mini VFD, please help me if anyone has had the same experience. Thank you so much

Post by timvh on Specify Input Configuration "OnDialogClosed" Action to only react to certain Dialogs ^{CODESYS Forge talk (Post)}
What maybe helps is the Visu Dialog ST demo project: https://store.codesys.com/en/visu-dialog-st.html This has an application IECOpenDialog where dialogs are opened using the VU.FbOpenDialogExtended function blocks. The fbOpenConfigurationDialog call has a reference (interface) to the "close listener" FB of which it's method is automatically called when the dialog is closed. This way you can create specific function blocks for each dialog when it is closed and do what you want with the data that might have been changed.

Post by eschwellinger on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
you need at them moment a download once (for the configuration files generated including addresses) then stop the plc - exchange the persistence file ( without the config file) This will be improved to 3.5.18.6 and 3.5.20.0. (possible then to generate offline bootproject including full persistenmanager files) - this is if you have not 100% the same bootapplication on the devices. In case you copy the whole Application (PLCLogic) directory it should work out of the box - but only with 100% same bootprojects as mentioned above. By the CODESYS Automation Server would help solve this too.

Post by nathant on Can't open online view of FB instance from code editor, only from Device/POU windows ^{CODESYS Forge talk (Post)}
Hello, The title pretty much says it all. When trying to open a FB from the CFC/Ladder/SFC editors while online, the FB does not open in an online view of that specific instance. Instead, it opens an offline view with '???' shown for the value of any variable. This makes debugging extremely cumbersome, as I have to find each FB in the POU window and select the specific instance I am trying to view. Anyone know the cause/solution for this? Thanks.

Hello, We encountered the same issues on both recipe library versions 4.2.0.0 and the newest 4.3.0.0. The Arrays of structs get saved correctly but loading them restores only some indexes, while others get lost or completely wrong. We have been using the same recipes for the last two years on recipe manager vers. 3.5.17 withoud issues. There also seems to be a different behaviour in vers. 4.3.0.0 but it's still incorrectly loading the recipes. Did you find any workaround or solution? Codesys version used: 3.5.19.50

the TCA9548a does not work in Codesys. In Pyton this is only queried once and in Codesys cyclically. Of course you can also insert a terminating resistor in each port, then you should have no problems. I use this one: https://botland.de/8-bit-multiplexer/12723-qwiic-mux-breakout-8-kanal-modul-mit-i2c-multiplexer-tca9548a-sparkfun-bob-16784-5904422341428.html You can simply set the library to the latest version. You do not need Oscat. Do you need an example project for the BMP280?
